A Sony PlayStation Emulator for the PC.
Many of you sent us mails wondering how they can get the emu configured correctly. So,
in order to help you configuring it for the first time, We added this section to the FAQ.
1) Getting all necessary files
First off, you need the emulator, all plugins you want to use and the BIOS itself.
You can get the first two combined in a nice Installer from PSXEmu.com (browse to
http://www.psxemu.com/epsxe-download.shtml). We won't supply you with URL's for the
BIOS as it is copyrighted by Sony. But you should find it easily by browsing the web.
Now you need to get the plugins configured properly.
2) Choosing the best GPU plugin
When going after compatibility, you should use Pete's Soft GPU plugin, it's the one
with the highest compatibility. When that one doesn't work with a game others have
gotten working, you've probably made a configuration error. You should also use this
plugin when you've got troubles getting certain game situations to display properly
(for example the FF8 battle menus).
Now here's a list for the best plugins for the most popular graphic cards:
3dfx Voodoo 2 --> Lewpy's Glide plugin (could crash with certain drivers)
3dfx Voodoo 3 --> Pete's D3D (DirectX 7) or Lewpy's Glide plugin
3dfx Voodoo 4/5 --> Pete's D3D (DirectX 7) or Lewpy's Glide plugin
ATI Radeon --> Pete's OpenGL plugin
ATI Rage 128/Expert --> Pete's D3D (DirectX 7) plugin
nVidia GeForce 1/2 --> Pete's OpenGL plugin
nVidia TNT/TNT2 --> Pete's OpenGL plugin
Matrox G200/G400 --> Pete's D3D (DirectX 6) plugin
... the rest --> Pete's D3D (DirectX 7) plugin
3) Choosing and configuring the CD-ROM plugin
Windows 9x/ME + IDE CD-ROM --> ePSXe CDR ASPI Core 1.2.0
(Requires an ASPI layer, Win9x/ME comes with one.)
Windows NT/2000 + IDE/SCSI CD-ROM --> ePSXe CDR WNT/W2K Core 1.2.0
(Does not require an ASPI layer.)
Remember that you need an ASPI layer to get ePSXe reading CDs with OTHER plugins
using Windows 2000. You can get more infos on this further on in this FAQ!
When those settings aren't working for you, one thing you can do is to create an
ISO from the original CD using a burning app like CDRWin or WinOnCD. Keep in mind
that you should get better performance using an ISO, compared to running a game
from a CD.
4) Selecting the best sound plugin
ePSXe SPU Core 1.2.0 --> Good & fast sound, but still has some problems left.
Pete's MIDAS SPU 1.7 --> A good sound plugin which uses the latest SPU API.
Null2's SPU 1.35 --> Slowly became one of the best SPU plugins, recommended.
5) Choosing the correct BIOS
ePSXe has been mainly tested with the SCPH-1001 and the SCPH-7502 BIOS files, which
are therefor the BIOS files we mostly recommend.
6) Getting through the other settings
Now that you've selected and configured the plugins of your choice, here's a list of
the rest of the settings and how we recommend you to set them. Still, some game require
Options --> SIO IRQ Always Enabled --> [DISABLED] - (F4 to toggle on/off)
Config --> CD-ROM --> Enable Accurate CD-ROM Timing --> [DISABLED] - (See notes in the GUI)
Config --> CD-ROM --> Disable CD-ROM Status --> [DISABLED] - (See notes in the GUI)
Config --> CD-ROM --> Disable Real-Time CD-ROM Status --> [DISABLED] - (See notes in the GUI)
Config --> MDEC --> Enable MDEC --> [ENABLED]
Config --> MDEC --> Enable MDEC Timing --> [ENABLED] - (See notes further down)
Config --> Sound --> Enable Sound --> [ENABLED]
Config --> Sound --> Enable CDDA Sound --> [ENABLED]
Config --> Sound --> Enable XA Sound --> [ENABLED]
Config --> Sound --> Enable XA Read --> [ENABLED] - (Needs a fast system, F6)
Config --> Sound --> Enable SPU IRQ hack --> [DISABLED] - (Needs a fast system)
And now you should be able to enjoy one of the best free emulators out there. When you
still have problems or suggestions for this FAQ, feel free to post them on our message
board or mail us!
Q: Who are the developers of this great application?
A: The programmers aren't new to the scene. The one you all have probably already heard of
is _Demo_, one of the authors of the best SNES emulator out there: ZSNES! The other two
are calb, experienced programmer from emulators like ESNES, and Galtor, who is new to the
emu scene, but still is a skilled programmer. When you want to learn more about them, make
sure to check out the interview with Galtor at http://www.psxemu.com!
Q: Game X doesn't run. What can I do to get it running?
A: There are certain things to do before giving up on a non-working game. First off, you could
use another plugin, since not all plugins work with every game. We suggest you use Pete's
plugins for GPU (OpenGL, D3D or Soft), since they provide the best compatibility ... see the
plugins section for more plugin troubleshooting. Then, you could try to disable MDECs, since
some games crash when they try to show the opening movie. In case you're running the game from
an ISO file, try Daemon Tools, since some games only work properly with that tool. Some people
also informed us that using a different BIOS version has helped them getting the emu working.
Now, check if your CD-ROM drive at least TRIES to read the game CD ... when it does nothing on
start, try another plugin (see plugins section for more help). If this isn't the problem, you
can try to load the game patches using the "Cheat" option in ePSXe. Some games have special
workarounds found in these patches with allow them to run, or fix some in-game bug.
And last but not least, you should try to start the emulator with the option '-cdtiming' or
activate the "Enable Accurate CD-ROM Timing" option in the CD-ROM configuration screen. If all
this didn't help, you just need to wait for the next version, but hey, this emulator is free so
please don't send any E-Mails to the authors asking for game X to work in the next release.
Q: Which BIOS files are the best to use with ePSXe?
A: After the testing stage, we found out that the SCPH-1000, SCPH-5000 and SCPH-5005 don't seem
to work with ePSXe. We suggest you to use the SCPH-1001 and SCPH-7502 BIOS, since they've worked
great during our tests!
Q: Can I use those Region X patches for the Region Y versions of the games as well?
A: Nope, sorry... each patch is designed for a certain region of the game, and will most likely not
work with another region.
Q: Does ePSXe support changing discs in multi-disc games?
A: ePSXe (version 1.0.1 and on) includes a "Change Disc" option, which can be found by going to
Load -> Change Disc! This function still has some bugs, but could work for several games. Another
way to get past the disc changes is to check if the game creates a savegame at the beginning
of the next disc (games like Parasite Eve and Final Fantasy usually do that). In that case,
simply save, exit the current game, load ePSXe again with the next CD and continue playing
with the created savegame.
Q: How can I show the frames per second (FPS)?
A: Just press the "Del" key, this should work with most (not all) GPU plugins.
Q: Can you actually play audio CDs in the "Run BIOS" option?
A: Nope, that isn't supported.
Q: For VGS, I used Daemon Tools to play ISOs, What should I use for ePSXe?
A: Nothing like that. ePSXe comes with a built in "Run ISO" function, which easily allows you
to run a .bin (CDRWin format), or .iso file from your HDD! But, Daemon Tools can have a
higher compatibility rate, so you may want to still try it.
Q: Can I play backups with ePSXe?
A: Well, it has been proved several times now: It's nearly impossible to provide 100%
protection of backup's! And since Sony isn't even able to prevent the PSX console
from being used to play backups themselves, why should emulators be any different?
And, since ePSXe uses the PSEmu Pro plugin system, you're even able to play ISO's
directly from your hard disc!
Q: During certain games (for example Driver, Ridge Racer, X-Men Vs. Street Fighter etc.),
I can press whatever I want to, the emulator doesn't react. Can this be fixed?
A: Yes, to get the controller working again, you just need to enable "SIO IRQ always on"
in the misc menu or simply press F4 during emulation!
Q: ePSXe keeps crashing on me at different locations, what can I do?
A: One thing that ePSXe seems to be really sensitive to is bus speeds which are out of
spec. This means you most probably overclocked your PC. If you are experiencing
problems with ePSXe crashing constantly, but never at the same location, then it
could be pointing to this problem. The only way that your bus speeds would be out
of spec would be if you are overclocking, so if you are then you might want to try
setting your processor back to its default settings with the PCI bus being at 33mhz
and the AGP bus being at 66mhz. During testing the bus speeds only seemed to effect
Final Fantasy IX, but it might also effect other games as well, so if you are having
random crashing problems with any game, this would be something to give a try.
Q: I keep getting some strange errors in the command line box in ePSXe...something
A: If you're having troubles with errors related to mci, or an empty black screen, upgrade
your ePSXe and use one of the internal CD-ROM plugins, depending on your OS. If you don't
wish to upgrade, or want to use another external plugin, then disable CDDA under Config
Q: ePSXe just gives me a black screen!
A: See the previous question relating to CDDA.
Q: Yay! ePSXe 1.2.0 supports save states! But, how do I use them?
A: In order to use save states, you must get used to the keys which allow you to take advantage
of them. First, F1 is to save to the current slot, F2 to increase the slot number (You can
see the current slot in most GPU's on-the-fly menus), but there is a max of five slots. And
finally, press F3 to load the savestate in the current slot. Also, Save States are only supported
with the following plugins, and their future revisions:
Kazzuya's Software GPU 1.6 Alpha
Knack's Software GPU 0.84 Beta
Lewpy's Glide GPU 1.31
Pete's Direct3D GPU 1.47
Pete's OpenGL GPU 1.47
Pete's Software GPU 1.47
ePSXe SPU Core 1.2.0
Null2's SPU 1.35
Pete's MIDAS SPU 1.7
This list will be added to as authors update their plugins to support ePSXe's save state function.
Q: I'm so excited about ePSXe 1.2.0 including Force Feedback support, but there's one problem,
it won't work! What am I doing wrong?
A: (Answer provided by Wormie, owner of PSXFanatics.com)
"I have seen some people having troubles getting Force Feedback to work for them. I don't think
it was ever mentioned before, but during testing I found this feature it only seems to work when
the controller is set as analog/digital in the controller setup for ePSXe. Also when setting
up the analog controlls, I personally didn't mess with the options at the very bottom of the
controller ... I just setup the 4 way directional pad area (or whatever it's called) with the
analog stick instead of the directional pad."
Q: Are there any command-line switches I should know of that are not mentioned in ePSXe's docs?
A: There are quite a bit of undocumented switches, even some that aren't mentioned when using the
'-help' switch! For your reading pleasure, here is a list of all known command-line switches
in ePSXe 1.2.0 and their function(s):

**** - Mostly used by developers/testers.
***** - You can try '-p 12' to increase speed in some games, but it will normally produce input problems.
Q: After I upgrade ePSXe, my controller no longer works!
A: First, make sure you are running DirectX 7.0a or 8.0a, as versions 7.0 and 8.0 have
DInput problems which were fixed in their 'a' counterparts. You can get the lastest
DirectX from http://www.microsoft.com/directx If that doesn't fix your problem, delete
the ePSXe Configuration registry entry under 'HKEY_CURRENT_USER\Software\Epsxe\Config'
using Microsoft RegEdit, if you find that too hard, I suggest a powerful, yet easy to
use registry editor, RegCleaner (www.jv16.org). After deleting the entry, reconfigure
your controller (and everything else =P) in ePSXe.
Q: ePSXe doesn't work with my controller, but I've seen others with the same use it with no
problems! What am I doing wrong?
A: See the first part of the previous question pertaining to DirectInput problems experienced
when upgrading ePSXe.
Q: ePSXe is way too fast! How can I slow it down?
A: If you're using Pete's GPU plugins, check off the 'Use FPS Limit' checkbox, and select 'FPS Limit
(10-200)', and manually define your FPS limit, it is recommend you input 60fps for NTSC J and U/C
games, and 50fps for PAL games. If you need a little speed boost, try incrementing the fps by a bit,
maybe by 10 or so.
If you're using Lewpy's Glide GPU plugin, select the 'FrameRate Limit' option, choose 'Custom',
and put 60fps for NTSC J and U/C, and 50fps for PAL. If you feel it's a bit slow, try boosting the
speed a bit by incrementing the fps a bit, I suggest 10fps or so, but your mileage may vary.
If you're using Knack's Software GPU Plugin, select the 'fps limit only' option under the
'Framerate > Adjustment Type' menu. It's automatic, as far as I know, there's no way to
customize it, yet ;)
Q: When I save my game using the memory cards after loading a save state, it saves fine, but
the save data is missing/older when I play it the next time, what gives?
A: ***WARNING: This answer has yet to be confirmed by the authors, although our tests verify it***
(Answer provided by Lewpy, developer of Lewpy's Glide GPU plugin)
Here's a step-by-step of what I believe happens:
1) You start the game in ePSXe and the memcards you have selected in the GUI are used.
2) You make a SaveState - this includes PSX RAM, GPU VRAM, SPU RAM, and memcards (<- important!)
3) You quit ePSXe, go do something really important in RealLife™, and then come back
4) You start the game in ePSXe and the memcards you have selected in the GUI are used.
5) You load the SaveState - here is the problem: what should happen to the memcards?
They need to be restored from the SaveState, but should they overwrite the ones that
you have selected in the GUI? That _could_ trash some important saves! So the safe
route is taken: some memcards called temp.000 & temp.001 are created from the SaveState,
and ePSXe then uses those for the rest of the game, until closed.
What does this mean?
1) Your original memcards are not overwritten by the SaveState
2) Your saves _are_ being recorded after the SaveState load
3) You have to manually recover the memcards once you quit ePSXe, BEFORE you load another
SaveState (as this will overwrite the previous temp.000 & temp.001 files)
To recover the memcards, go to the memcards directory and rename temp.000 & temp.001 to
whatever you like. Then, in the ePSXe GUI, point it at these memcards. There may be a more
sensible way around this quandary, but at least at the moment ePSXe plays it the "safe" way:
imagine the "knee-jerk" reaction that would happen if ePSXe started overwritting memcards
with the ones from SaveStates ;)
Q: Can I use ePSXe's 'Cheat' option to use GameShark/Pro Action Replay/etc. codes?
A: With some outside tools, it is possible, but that's not what ePSXe's 'Cheat' engine
was meant for. It is meant for the usage of loading memory addresses which can be
used as workarounds for bugs, without having to update the ePSXe executable. If
you wish to use GS Codes and the like with ePSXe, we suggest you use [pec]. You
can learn more about and download [pec] at http://pec.emucheater.com.
Q: Does [pec] work with ePSXe 1.2.0?
A: As of this writing, the external version of [pec] (version 1.2) DOES NOT work with
version 1.2.0 of ePSXe. If you want to use GameShark codes in ePSXe, you should use
JNS's new creation, [pec] The Plugin. [pec] the plugin uses the PSEmu Pro Plugin
interface, which allows for extended compatibility, faster execution, and more!
The latest version is 1.3, and can be downloaded from http://pec.emucheater.com.
Please consult the [pec] documentation if you have any trouble with the program.
Q: I made a save state with a multi-disc game on one of the later discs, after switching
discs during play. When I started off the disc I was currently on when I went back,
the save state would not load, what gives?
A: Each time you wish to load your state on another CD, you must insert the first CD you
made a save state on (typically Disc One), switch to the current disc you're on, and
load the save state. I know this seems tedious, but at the moment, it's the only
workaround known to help with this issue.
NOTE: This has only been tested on FF9, if the bug does/does not occur in other
multi-disc games, please mail us.
Also, some people think that renaming the save state file _may_ be another solution,
but this is untested. If you test this solution, and find that it works/does not work,
e-mail us ASAP.
Q: Some games (only a few), are giving me trouble saving, what's up, I thought this was fixed?
A: Just use the old F4 trick used for ePSXe 1.0.1, for more info, check out the 'Legacy Support'
section of this FAQ below. I don't know exactly which games this effects, but if anyone can
clue me in, please send an e-mail, you can find our contact e-mail in the 'Credits' section.
Q: What's the best plugin to use for graphics (GPU)?
A: Use Pete's OpenGL plugin for best graphics, if your card supports OpenGL, and use
Pete's Software GPU plugin for highest compatibility. You can get both from our
ePSXe plugins page.
Q: I'm using Tratax's ASPI 1.2 plugin. When I start a game from CD-ROM, my computer
just sits there and does nothing. What's wrong?
A: Just wait around 30-60 seconds and let it load, the CD-ROM should boot afterwards.
Q: I own a Voodoo 3, and I'm using Pete's GPU plugins. I configured the plugin,and
selected "Nice" in order to get nice graphics. But then emulator crashes. Why?
A: It's simple: Pete's plugin activated 32-bit color when you press "Nice", and the
Voodoo 3 doesn't support anything more than 16-bit color. You need to lower the
color depth in order to fix this problem!
Q: I'm using Lewpy's Glide plugin for my 3dfx card. But every time I try to run a
game, the emulator crashes.
A: Download the latest version of Lewpy's plugin from our plugins section, it should
be fixed in the latest version now! Also make sure you're using the latest ePSXe!
Q: I'm using Win2k and can't get the CD-ROM working, no matter which plugin I try!
A: In the latest version, two new CD-ROM plugins have been added. For more details
about those changes, take a look at the "Getting Started" part included above
in this FAQ!
Q: I've downloaded and extracted Null2's SPU to my Plugins directory, but it's not
showing up as a choice under SPU Plugins in ePSXe, please help!
A: Null2's popular SPU plugin requires the Visual Basic 6 runtimes in order to
function properly, and won't even be listed unless they are installed.
Win2K, WinMe, and Win98SE(?) already come with them, but Win95 and Win98 do
not. You can grab yourself a copy of the runtimes at:
Q: How can I get Resident Evil 3 PAL working?
A: You need to use a patched backup version, the original one is not working.
Q: How can get Final Fantasy 8 PAL working?
A: You need to use a patched backup version, the original one is not working.
Q: Chrono Cross locks up when I use the teleporter, is there a way to fix this?
A: Both 1.0.0, 1.0.1, and 1.2.0 freeze when you use the teleporter in the game, but you
can unfreeze it and get past this point by hitting F3 in ePSXe 1.0.0/1.0.1, and
F7 in ePSXe 1.2.0.
Q: How can I get Final Fantasy 9 US/JAP working?
A: It isn't playable in ePSXe 1.0.0 due to an emulation bug. Anyway, this bug has
been fixed in 1.0.1 and higher :). When using Pete's hardware (D3D/OGL>
plugins, remember to set Offscreen Drawing to standard in order see the battle
menus, and set Framebuffer Textures to Gfx Card Buffer (If your video card supports
it, check Pete's docs) or Full VRam Primitives (Note: Full VRAM Primitives WILL slow
down ePSXe immensely), so you can see the effect which occurs every time you enter a
Q: I saw screenshots of ePSXe running Spiderman/THPS1/THPS2, but I can't seem to get
them to work without messed up graphics.
A: In order to play these three games on ePSXe, you must have Pete's (D3D/OGL/Soft)
1.41 (or higher) plugin revision(s).
Q: What's this?!?! The ePSXe docs say FFIX PAL is supported, but my version does not work!?
A: Final Fantasy IX PAL needs a patch to be applied to an ISO image of an original CD
before it can work with ePSXe 1.2.0. Many people from the UK aren't able to locate
a patch for their region yet, simply because there one doesn't exist yet! As of this
writing, there are only patches for the german, the french and the spanish versions
released. You can grab the PPF patches, and the engine to apply them with at PSXEmu.com
Q: Help!! The '-legaia' switch doesn't seem to fix the problems in Legend of Legaia in
A: This was an error on the authors' part, the correct switch to use via command line is
NOTE: Enabling Accurate CD-ROM Timing in options may produce the same effect, but to
be safe, it's best to use the switch.
Q: I can't seem to get Saga Frontier 2 PAL working, is there anything I can do?
A: In order to play Sage Frontier 2 PAL in ePSXe, you must remove it's protection by patching
an ISO image, you can find the patch by surfing the web. Also, you must run ePSXe with the
'-auto' command-line switch.
Q: ARGH! FF7 worked fine in ePSXe 1.0.0 and 1.0.1, but in 1.2.0, it crashes when I choose 'New Game',
what's going on?
A: The authors are aware of this bug, and it's going to be looked into. Until then, a quick fix is to
either use an earlier version of ePSXe, or get a save file for FF7 at the beginning of the game,
since the 'Continue' option is still working fine ;)
Q: How can I get Soul Reaver functioning in ePSXe 1.2.0?
A: The answer is quite simple really, simply check off the option 'Disable Real-Time CD-ROM Status'
under Config > CD-ROM in ePSXe.
Q: How can I get Cool Boarders 2001 working properly?
A: This bug popped up somewhere in ePSXe 1.0.1, and remains in 1.2.0, to get Cool Boarders 2001
working, start ePSXe with the '-nogui' command-line switch.
Q: How can I get Front Mission 3 going?
A: Use the same method as the one for Cool Boarders 2001, start ePSXe with the '-nogui'
Q: How can I get Breath of Fire 3 PAL started?
A: Use the same method as the one for Cool Boarders 2001, start ePSXe with the '-nogui'
Q: Gran Turismo 2 locks up after the intro screens, is there any way to fix this?
A: Sure, simple enable 'Accurate CD-ROM Timing' under Config > CD-ROM, or start ePSXe
with the '-cdtiming' command-line switch.
Q: Dino Crisis locks up after a few screens, how can I get it to work?
A: Well, the US (NTSC U/C) version has anti-mod protection, which needs to be removed in
order for it to work with ePSXe. This can be done via a PPF patch for the game, which
you can obtain by searching the web.
Q: Dino Crisis 2 locks up after a few screens, similiar to Dino Crisis, what's up?
A: As with Dino Crisis 1, the US (NTSC U/C) version of this game has anti-mod protection,
which needs to be removed inorder for it to work with ePSXe. This can be done via a PPF
patch for the game, which you can obtain by searching the web.
Q: When a character joins my party in Chrono Cross, ePSXe locks up, is there a
workaround for this?
A: When this happens, simply press F7 on your keyboard, and ePSXe should return to
normal, and you may continue your game of Chrono Cross ;)
Q: How can I stop Breath of Fire 4 NTSC U/C from crashing when I enter the town
A: Load the breath_of_fire_4_usa.cht cheat file in ePSXe's /cheats directory. You can
do so under Cheats > Edit Cheat Codes. Load the cheat by selecting it after pressing
the 'Load' button.
Q: How can I stop the backround music from looping in Megaman X4/Rockman X4, like it
does in MMX5/RMX5?
A: In order to have the music playback properly, start ePSXe with the command-line switch,
Q: How can I stop the backround music from looping in Megaman X5/Rockman X5?
A: As with MMX4/RMX4, in order to have the music playback properly, start ePSXe with the
command-line switch, '-noseekinxa'.
Q: Which 3D API's does ePSXe take advantage of?
A: Since ePSXe uses the PSEmu Pro plugin system, it provides support for all
important APIs: OpenGL, Direct3D, 3Dfx's Glide and pure software mode. For more
info about the plugins and downloads, refer to our ePSXe plugins page!
Q: Can ePSXe use VGS/Bleem memory cards?
A: Yes, from ePSXe 1.0.1 on, you can use memory cards in VGS' or bleem!'s format.
Simply select the memory card what you want to use in the specific slot using
config -> memcards, start the game and play :)
Q: Does ePSXe support hardware anti-aliasing?
A: (Answer provided by Lewpy, PSEmu Pro plugin developer)
"Since ePSXe uses PSEmu Pro GPU plugins, then you have full access to the hardware
anti-aliasing that your hardware/drivers combo provides, as long as you use a hardware
accelerated GPU plugin. Smoothing (i.e. bilinear filtering) is possible, but not
without glitches, since the PSX games were not designed to allow for filtering.
Increased screen resolution is also possible, but it doesn't allow for increased
model accuracy within the PSX game. You can notice this within racing games as distant
cars draw closer, there resolution is still very low. Only some kind of HLE could
improve that (extracting the game data away from the actual PSX hardware ....
Q: How do I dump a PlayStation BIOS?
A: To dump a PlayStation BIOS, you need a GameShark or Action replay and a PC comms
link. To start, you need either a real Caetla module or go to altavista and search
for "Caetla" (it's a BIOS replacement for your module, so properly read the included
documentation before installing it!!). Now upload "Caetla", and use use the caetla
commands for downloading a binary memory image from the region 0x0bfc00000 -
0x0bfc7ffff! Now save the image as SCPHxxxx.bin, where xxxx is your PSX's model number,
and ePSXe will recognise it and use it from now on.
Q: How do I find out what version of the PlayStation BIOS I have?
A: Open the PlayStation Bios file in WordPad or any other text editor, go down to the
bottom and you will see System ROM Version X.X YY/YY/YY (Z).
X is the number of the BIOS, e.g. 2.2
Y is the date of the BIOS, e.g. 12/04/95
Z is what region the BIOS is from, e.g. J for Japan,
Q: Why doesn't my favorite game, X run with ePSXe?
A: Well, this emulator is done in the authors FREE time, so they don't have to get any
game running just for you. Certain emu authors like to have poll's on their page to
see which game you'd like to work the most. If they do not, please don't mail them,
they'll probably just ignore you. Same goes with us, we didn't code the emu, we can't
change anything about that.
Q: Can you get game X working in the next version? And when will you release it?
A: See the previous answer above!
Q: Where can I find the PSX BIOS? The emu asks me for it every time.
A: Please neither ask us nor the emu authors for the PSX BIOS file, we simply won't give
it to you since we're legally not allowed to. Search the web (I recommend
www.metacrawler.com), and you should find it quite easily.
Q: With ePSXe 1.0.1, my MDECs are actually running slower than 1.0.0! What can I do to
A: A simple solution to this is to just locate the ePSXe Configuration registry entry
found in KEY_CURRENT_USER\Software\epsxe in your windows registry, and delete it.
Restart ePSXe, reconfigure, and play!
Q: Help! Some of my memcards have gotten deleted for no apparent reason! What's wrong?
A: The ePSXe team recommends to backup your memory cards before using them with ePSXe.
This is because some NTSC games have problems with the current NTSC timing which can
result in the deletion of memcards. One suggestion is to try enabling PAL timing by
setting the timing to PAL with Options > Country > PAL. As usual, the best solution
is to upgrade to ePSXe 1.2.0 and higher, the problem has pretty much been resolved.
Q: Ok, I got FF9 working, but I get some weird sound bugs before entering a battle
and during the battle itself, is there a way to fix this?
A: This is a known bug in the SPU core in ePSXe 1.0.1, to rectify this problem, upgrade
to version 1.2.0 or higher.
Q: The ISO function doesn't run some games my friend can play from his CDs ... Why?
A: Upgrade your copy of ePSXe! In 1.0.0 the ISO function didn't apply patches yet to
ISOs, this has been fixed in 1.0.1 and future versions, and should work well now!
