Descargar eLoader v1.000






Readme:

This program builds on the original work done by Saotome to load homebrew EBOOT.PBPs into PSPs with HEN or Custom Firmware (CFW). Although HEN and CFW can generally load most modern homebrew, eLoader offers a way to improve compatibility with older programs.

eLoader is of most use for PSP Lite owners running CFW. This loader will allow them to run homebrew based on 1.50 kernel which otherwise would not be able to run due to the incompatibility of the PSP Lite and the 1.50 kernel.

Since eLoader will also run in any CFW it will be also useful for those developers not having a PSP Lite and wanting to check that their code will run on it.

It currently cannot run all known homebrew, but it uses a number of tricks to get substantially further than ever before. Known limitations are:

* Can't run most kernel-mode applications.
o That means anything that emulates ISOs/UMDs.
* Some minor system calls are still unsupported.

It's also still very much in development, so you should expect a few bugs, and for not every EBOOT to run perfectly. An up-to-date list of known working EBOOTs can be found at the homebrew database listed above.
Major new features in this release

Added support for HEN and custom firmwares including the PSP Lite.
Details of Kernel Mode Support

In eloader 1.000 it is possible to make use of kernel mode using "constructor" procs, this therefore gives the ability to patch kernel memory before the user mode thread starts (in the same way that firmware v1.5 can)

The main thing that you can not do at the moment is start a new thread in kernel mode. Note that this is the same level of kernel-mode support as the 0.995 release. We intend to dramatically improve kernel-mode compatibility in future releases.
TERMS OF USE

This software is made available for use as-is, without any guarantee of usability, safety, fitness for purpose etc. We've taken all reasonable precautions to ensure that it cannot damage your PSP, but cannot be held responsible for any damage caused.

You are not permitted to sell this software. If you paid money for this program (most often through eBay), you should demand a refund of your payment, and report the seller to the appropriate authorities.

This program is not intended to aid piracy of any form. Use for piracy is strictly forbidden - we want to support software developers, not steal from them.
To install eLoader

Copy the contents of the MS_ROOT folder to the topmost folder on your PSP memory stick. If you've done this correctly, you will end up with a set of files within the folder

/PSP/GAME/eLoader

on your memory stick.
Installing Homebrew

If you've chosen to install Installotron, then you can automatically download and install a selection of popular homebrew to your PSP, so long as you have a network connection configured on your PSP. Just run eLoader as described below, and then select and run Installotron, to select the homebrew programs to install.

Otherwise, or if the homebrew you want to use is not supported by Installotron yet:

Copy the homebrew you want to run to your memory stick. Usually, this means unzipping a directory that contains an EBOOT.PBP file to somewhere under /PSP/GAME/. The exact location and folder name usually doesn't matter, but for best compatibility you should try to use the same names as originally shown in the homebrew ZIP file.

If the instructions with the homebrew contain separate steps for v1.0 and v1.5 firmwares, then usually you'll get best results by following the v1.0 instructions.

NOTE: If the homebrew is written in LUA, you need to copy it to a subdirectory under the your LUA Player "APPLICATIONS" folder.
Running eLoader : via HEN and Custom Firmwares

In order to run eLoader just goto to the "Game" menu on the PSP menu, then "Memory Stick", then select the "eLoader IPA" program.

This will cause eLoader to load up its menu ("eMenu") from which you can choose the homebrew you would like to load.
Using eMenu

* The loader displays a list of folders in ms0:/PSP/GAME and ms0:/PSP/GAME150. Use the up and down buttons to change the current selection (highlighted with a black line), and X or O to run the homebrew in that folder.

NOTE: To load LUA applications, you need to run LUA Player first, which will launch Lowser and let you browse to open the application.
* Once you select some homebrew to load, the menu will exit, and after a few moments, the loader will either display an error message, or the homebrew will start.
* To exit the homebrew, you need to reboot your PSP. The loader contains in-built support for rebooting, by holding the Left Trigger, Right Trigger and START buttons together for a few seconds. If this doesn't work, then you can also reboot by removing the battery, or holding the power switch for at least 10 seconds. Note that sometimes after a software reboot, the loader will hang if you try to run it again. This seems to be much rarer if you enter USB mode briefly, before running the loader again.
* Other buttons:
o Triangle will turn on USB mode.
o Square will take a screenshot of the menu.
o The L and R shoulder buttons change the PSP's clock speed.
o SELECT will show usage instructions, and rescan the memory stick for new homebrew.
o START will exit the menu.
o HOLD will put the PSP into 'slumber mode' - the clock speed is set to minimum, and the screen is blanked. You can get further power saving by holding the 'SCREEN' button to turn off the screen, before engaging 'HOLD'.
* If you get the message 'Not Homebrew', it means that the selected folder does not contain the file 'EBOOT.PBP' in the topmost subfolder. This usually means that you've incorrectly installed the homebrew.

Using a different menu

v1.000 of the loader ships with a default menu, emenu--.pbp.

It's also possible to install optional alternative menus, such as 'Choice'.

The loader will use emenu--.pbp menu by default. If you want to use one of the alternatives, then edit the loadmenu1000.cfg file (with Notepad, or any other text editor), and change the following line:

menu=ms0:/psp/eloader/emenu--.pbp

to point at the location of the alternative menu's .PBP file.
Troubleshooting

If you have problems with an individual EBOOT getting to the "Press X to launch the program" screen, but crashing immediately after, here are a few things to try:

* Check whether it is already on the list of non-working EBOOTs at www.psp-homebrew.eu.
* Make sure you are trying to run it as the first thing you do after a clean reboot of your PSP
* Use v1.0 EBOOTs in preference to v1.5.
* Make sure that you read any README supplied with the homebrew, and followed the installation instructions (for v1.0, preferably) carefully.
* Make sure that any support files (e.g. WAV files, graphics files) contained in the ZIP file are copied into the same place on the memory stick, relative to the EBOOT file.
* Experiment with the launcher options in the configuration file. (see below)
* Check the forums at pspupdates.com or noobz.eu - someone might already have found a way to make this EBOOT work.
* If you see a message during the loading process, saying "Found suspicious hard path", then this means the loader detected that the application depends upon being in a specific location on the memory stick. Usually the path will mention a specific file - try moving the application folder so that the file is in the place shown.

If you find that one of these steps helps, then please send us details on what you did to make the EBOOT work - we can build the workarounds automatically into the next version of the loader.

NOTE: If the eLoader aborted the process before reaching the "press X" screen, then don't bother trying these steps - there's no way that EBOOT will currently work, but please remember to send the details of the error message to me, so that I can attempt to change the code to make it work.
Configuration File

v0.8.5 and beyond of the loader support configuration via a file, /psp/game/eloader/LOADER1000.CFG. See inside the file for basic details on what the various options do. For most purposes, the defaults should be sufficient.

If you want to try to tweak the options for a specific EBOOT, here are some pointers:

* Each EBOOT has a special signature that identifies it to the eLoader. To find out the signature, use the bundled Windows program "EBOOT_SIGNATURE.EXE". This will tell you the name you need to use for the config file section header for the EBOOT.
* The following options are the most common ones to change to make a specific EBOOT work. Often, changing one of these (more-or-less at random) will fix the more sensitive EBOOTs such as USER_LUA. Try changing these one at a time, in this order, for best results.
o passparameters
o confirm
o callinit
o clearscreen
o initbssfull
o initbsspartial
* If you want to suppress screen-spam during loading of a known-good EBOOT, you can try changing these options. You may find that the EBOOT stops working after changing an option - if so, just change it back.
confirm displays the 'press X to start' menu.
unknownNIDwarning warns you if some system calls requested by the EBOOT couldn't be identified.
patchkernelwarning warns you if the EBOOT is kernel-mode. For some EBOOTs, this doesn't matter.
ignorefixedpath warns you if the EBOOT contains a suspicious- looking filename, that implies it might need to be run from a fixed location on the memory stick.

If you find some new configuration parameters that work well for a specific EBOOT, please email us at homebrew@noobz.eu, or make a post on the eLoader forums at forums.noobz.eu.
Future plans

Please see the "Work In Progress" page at www.noobz.eu.

If you find some new homebrew that either does or doesn't work on your PSP, then please consider adding your results to the PSP homebrew database at www.psp-homebrew.eu. Anyone with a free account there is able to add to the data, and it's a great way of checking whether other people have been able to run particular homebrew on a similar PSP setup to yours.
Acknowledgements

This app wouldn't have been possible without the toc2rta TIFF exploit code, or Saotome's hard work on the first beta EBOOT loader, or the support of the fantastic folks at the ps2dev.org forums (especially Groepaz's list of NID :) syscall mappings, and Vampyre's continuing efforts to expand that list). And later, of course, the TIFF exploit that opened up access to homebrew on v2.0-v2.8 - thanks to psp250, Skylark, NOPx86, Jim Paris, Chris Swindle, joek2100 and Fanjita for that.

Thanks to Edison Carter (and later Jim Paris and psp123) for the development of the GTA savegame exploit, which made homebrew possible on v2.01+.

More thanks to hitchhikr, for the LoadExec kernel mode exploit, which we rely on for v2.70 and v2.71 support.

Thanks to Alex Richter for Installotron development.

Thanks to all the forum mods at PSPUpdates.QJ.net, and operators in the #fanjita IRC channel, for supporting all the questions from eLoader users. Special thanks to Serideth and Wakaru, who seem to never sleep.

Thanks also to the many beta testers for their hard work beta testing, as well as many other individual email contributions with information on which EBOOTs are working.

If you have found this program useful and want to encourage further development, please consider donating a small amount via paypal to donations@noobz.eu.

o Rewrote NID resolution code to support different firmware versions.
o Removed kernel-mode warning by default
o Improved audio stability
o Improved thread tidy-up upon program exit - no more dead copies of user_main lying around.
o Improved memory tidy-up and integration with system heap: this gives more memory available to homebrew, and is a factor in the GBA emulator now working.
o Massively improved stability, especially for GTA
o Added config option to not call exit callback (should help with apps that crash on exit)
o Added config option to not automatically prevent display dimming (saves power)
o Added config option to control system bus speed.
o Added automated installer for Windows
* v0.9 : Wifi support, stability
o Added wifi support! Now the loader auto-detects if the wifi libraries are loaded (via the wifi load method above) and offers them to homebrew for use.
o Added call to application exit callback, to allow RIN etc. to save state when L+R+START reset is used.
o Added memory reset after running the menu. This should make things much less sensitive to whatever has been run before them. Can be turned off in config.
o Added memory reset on exit - this might make it easier to restart the loader.

o Improved kernel-mode override patching logic.
o Attempt to kill surplus system threads, for stability.
o Run loader from reserved memory for increased stability.
o Tidied up some memory reuse in ELF section header handling
o Bundled graphical menu now filters to only display the names of EBOOTs for selection - all the surplus fluff is hidden. Also now handles v1.5 homebrew directory structure.
o Added option to allow L+R+START reset to go back to loader menu, rather than main menu
* v0.8 : Usability, compatibility
o Added capability to reboot the PSP without holding the power button. During any EBOOT, just hold Left Trigger, Right Trigger and START buttons for 1 second to exit the loader and reboot back to the PSP menu.
o Separated menu binary from loader binary, to allow custom menu creation. Included custom menu by Calum.
o Added kernel-mode override facility - allows the loader to attempt to load apps marked as kernel-mode, that don't really require kernel access. This doesn't enable a huge number of apps, but it does enable a few - e.g. ScummVM 0.5, PSPChess, Nethack. Expect more progress in the future.
o Relax requirement to resolve all NIDs. Now you can choose to ignore failed NIDs in the hope that they aren't required.
o Improved USER_LUA stability (by incorporating the 0.7 USER_LUA patch)
o Added PowerTick() call to prevent display dimming during play

o Filled in some missing opcodes from the disassembler
o Added syscall dereferencing to disassembler
o Added hook to sceKernelCreateThread, to improve thread monitoring
o Reduced screen spam during loading, by moving it to debug-only build
o Attempt to load more of the ELF sections into RAM if appropriate
o Retired hokey malloc implementation during file load, use proper memory blocks now.
* v0.7 : Compatibility, usability
o Implement simple internal memory manager, hooked onto firmware memory management, to boost memory pool available to applications.
o Hook thread allocation and exit, to allow for clean return to the loader from applications that support an Exit option.
o Improve code signature algorithm to distinguish between similar EBOOTs (fixes mis-identification of Casino Addict as SMS emulator).
o Added overclocking option : use left and right trigger buttons when choosing file to change CPU speed.
o Add NID resolution for Sircs function : enables PSP IR Remote function.
o Add USB stubs to user-mode LUA, and better debug info in case of script errors.
o Added left and right DPAD support in file-chooser, to go to the start and end of the list
o Now supports more than 20 files in a directory
o Found pathname hack to run PSP Rhythm Composer.
o Improved cache flushing, should improve reliability
o Added safeguard to prevent PSPSet from being run and bricking 2.0.
* v0.6 : Compatibility and stability
o bundle user-mode LUA player.
o only process stringtable section header and .reginfo, all others are unused.
o setup $gp register from .reginfo
o change folder thumbnail to smaller image, improves launch stability.
o added scan for EBOOTs with hard-coded paths.
o clear display RAM before starting some EBOOTs, to clear up some graphical anomalies.
o added direct seek to ELF header - much much faster file loading.
* v0.5 : More compatibility enhancements, bug fixes
o Better argc/argv handling, prevents a common cause of startup crashes (e.g. PSP Schedule).
o Made the 'return to chooser' function more stable. It now shouldn't affect how well the next EBOOT loads.
o Improved file scanning speed - large EBOOTs should load much faster.
o Added 'alternate startup parameters', use this to run Sega Master System emulator which was broken in v0.4.
o Introduced 'EBOOT signatures' : known workarounds for specific EBOOTs should now be turned on automatically, and install location can be automatically checked if a specific path is required.
o Added support for .init sections, should help avoid a few more startup crashes.
o Added option to return to EBOOT chooser on final confirmation menu.
o Version number shown on screen fixed.
o Lots more info in readme file.
o Various minor bugfixes.
* v0.4 : Usability & reliability enhancements
o Return to menu if possible after failed load. NOTE : this is a bit flaky, and mainly designed for quick checks for kernel-mode apps, etc. If something crashes after you ran through a few EBOOTs that wouldn't load, it's worth retrying it immediately after a reboot.
o Experimented with exception handlers for extra diagnostics, but this is not possible in user-mode (and anyway the appropriate syscall code is unknown for v2.0).
o Fixed overflow with more than 19 directory entries - now apps that failed just after EBOOT selection will get further.
o Added set up of argv, argc to supply path arguments - helps for Ghost In The Matrix, possibly others.
o Changed load address to 0x0860000, to allow more headroom for increased loader complexity. Also begun integrating Abu's loader code with the TIF file.
* v0.3 : Compatibility enhancements
o Allow browsing of multiple EBOOTs
o Change directory to selected EBOOT location (adds sounds to Attack of the Mutants)
o Restore screen mode before running EBOOT (improves reliability)
o Allow multiple text segments in ELF
* v0.2 : Original version, ported to C from original v0.1 EBOOT loader by Saotome.
