nds-bootstrap 2.9.0

In order to make things easier for me, and because I don't have Windows, I edited the HiyaCFW Helper Python script by jerbear64 and LmN in order to add a graphical user interface to it.

What it does:
Allows you to browse for your NAND backup, no need to place it at the same folder. Shows the option to choose the output destination, which should be a (preferably empty) FAT formatted SD card or any other folder. Downloads the latest HiyaCFW release and decompress it. Autodetects the console region from the NAND dump, downloads and decrypts its v512 launcher. Creates the patched 00000002.app and bootloader.nds for the custom firmware. Uses your platform's twltool (binaries for Linux and MacOS included) to decrypt the NAND. Mounts the decrypted NAND (OSFMount required for Windows) and extracts it to the chosen output destination. Installs the HiyaCFW and the patched files on the chosen output destination. (Optional) installs the latest release of TWiLightMenu++ (or any of the previous releases of it or DSiMenu++ or SRLoader placed at the same folder as the helper) on the chosen output destination. NAND mode:
Clicking on the integrated circuit button will give you a NAND mode, where you can uninstall unlaunch or install its v1.4 stable release, remove the No$GBA footer or add it. Recommended only for those with a hardmod.

Unlaunch es el primer exploit de bootcode lanzado para consolas DSi.
Toma el control con privilegios completos de acceso SCFG_EXT inmediatamente tras encender (incluso antes de iniciar el lanzador).
La instalación requiere un exploit DSiware funcional con acceso a SD/MMC, o un hardmod (modificación por hardware).
El exploit funciona con todos los modelos DSi comerciales, independientemente de la región y la versión de firmware.
Una vez instalado, iniciará el archivo bootcode.dsi desde la tarjeta SD (si está presente).
En caso contrario, reanudará el arranque del lanzador de Nintendo (con la advertencia de salud/seguridad y la música de arranque desactivadas, y eliminadas las comprobaciones RSA, de lista blanca y de región).
Before Installation - make a backup
Make a backup of your eMMC chip. If you have a DSiware exploit, use the "Backup DSi NAND" function in fwtool.nds, for example. With hardmod, just dump the eMMC chip. Either way, backup the unmodified file in a safe place, you can use it to restore the console to working state if something goes wrong (if the console gets totally bricked then you'll need a hardmod to do this).
The eMMC contains some console-specific files with RSA signatures - if that files get lost then you've a problem - there is no way to replace them by using equivalent files from another console.
Automatic Installation (requires a working DSiware exploit)
Installation is easy if you have a console with Flipnote installed (the game came pre-installed on many consoles, and it was also available as free download when the DSi shop was still online). However, some people may have deleted or missed downloading it, and it wasn't released in CHN/KOR regions. Anyways, if you have flipnote, use this exploit:
Flipnote Lenny or whatever it is called flipnote exploit for USA/EUR/AUS/JAP regions (requires https and youtube)
If you already have another exploit like sudokuhax then you could use that as well. There's also another flipnote exploit called ugopwn in some webforum (for USA region). All DSiware exploits are conventionally loading 'boot.nds' from SD card, so rename unlaunch.dsi to that name, then select Install Now in unlaunch (first making the backup, of course).
Manual Installation (via hardmod)
This requires soldering four wires to DSi mainboard (eMMC signals CLK, CMD, DATA0, GND), attach the wires to a SD/MMC card reader, and use some tool like HxD or Win32diskimager to dump the eMMC content to a 240Mbyte file.
Next, you will need the CID and Console ID for decrypting the eMMC image. There are several to obtain that values, and it's also possible to brute-force one (or both) values.
Decrypt the eMMC image using a tool like TWLtool (requires 64bit windows; there's also an inoffical 32bit built) Mount it to your OS using OSFMount or the like. Locate 520-byte 'title.tmd' file in the following folder: 'title\00030017\484E41xx\content' (the 'xx' varies per region), append 81400-byte 'unlaunch.dsi' at the end of the tmd file (tmd filesize is then 81920 bytes). Set the Read-only attribute for all files in above folder (else some DSi system tools may automatically brick your console by the deleting all files in the modified folder). Re-encrypt the eMMC image. Alternately, if you want to avoid the decryption, mounting, appending, protecting, re-encryption steps: Add a no$gba footer with CID and Console ID to the eMMC image, and run unlaunch.dsi in no$gba (with the eMMC named dsi-1.mmc) Note: Don't forget to enable DSi emulation, you may also need some further files like DSi BIOS rom images. Finally, copy the modified eMMC image back to the console.
Hotkeys
Boot hotkeys can be changed by clicking OPTIONS in unlaunch filemenu. Button A+B are fixed, and will bring up the Unlaunch filemenu. Buttons None, A, B, X, Y can be assigned to anything you want, for example:
Wifiboot (useful for developers) Unlaunch filemenu, or other homebrew filemenues, or official launcher DS Cartridge slot, or your favorite DSiware title(s) Older unlaunch version did have fixed hotkeys:
None: Start sd:\bootcode.dsi (if present) Button A: Start original launcher and show unlaunch version number (default when bootcode.dsi not present) Button B: Start ROM cartridge Button X: Start sd:\bootthis.dsi (instead of bootcode.dsi) Button Y: Skip Wifi init Dpad Up: Show red/blue/green to indicate relauncher bootstages Dpad Down: Do NOT invalidate cache on startup of installer Bootable Files
The bootcode.dsi (and bootthis.dsi) can be general nds/dsi files of following type:
Relative small self-contained titles (that are solely relying on the bootcode areas defined in their cart headers, without trying to load extra data) Homebrew NDS/DSi titles that are designed to load extra data from DSi SD/MMC slot (in many cases this may require something called "dldi" or so) (if it's a homebrew DSiware title then it should preferably use the Device List). Homebrew DSiware titles that access extra data by using the filenames from the incoming the Device List Not legit: Commercial DSiware titles (unless you have purchased them from DSi Shop when the shop was still online; but I think you didn't miss anything important if you didn't buy them) Not working: Games that load extra data from ROM cartridge slot instead of from SD/MMC slot (eg. ROM-images from commercial games) For DSiware, the Device List contains the names of the executable and public/private save files. With unlaunch, that names will be sdmc:/bootcode.dsi, sdmc:/bootcode.pub, sdmc:/bootcode.prv (or bootthis.xxx instead bootcode.xxx). The .pub/.prv files must exist (if the title is using them), and they must have the correct filesize (as specified in the cart header of the title).
SD Cards
Unlaunch supports SD/SDHC cards (max 32GB, preformatted as FAT16/FAT32). SDXC cards (above 32GB, preformatted as ExFAT) are not supported, neither by Unlaunch, nor by DSiware in general.
Reformatting SD/SDHC cards isn't recommended, or it should be done only with dedicated SD card formatting tools (that maintain cluster size matched to physical sector size). However, reformatting SDXC cards may help to get rid of the weird ExFAT format.
I would be glad to receive any non-working SD/MMC cards, so I could either support them or at least add some meaningful error message for such cards.

melonDS es un emulador de Nintendo DS, DSi y 3DS para Windows, macOS y Linux.
Características principales de melonDS
Núcleo casi completo (CPU, vídeo, audio, ...) Recompilador JIT para una emulación rápida Renderizador OpenGL, escalado 3D RTC, micrófono, cierre/apertura de la tapa Soporte de joystick Estados de guardado Varios modos de posición/tamaño/rotación de la pantalla (WIP) Wifi: multijugador local, conectividad online (WIP) Emulación de DSi DLDI (WIP) Complementos para la ranura GBA ¡y hay más planeados!
Cómo usar melonDS
melonDS requiere copias del firmware y de la bios de la Nintendo DS. Archivos requeridos:
bios7.bin, 16KB: ARM7 BIOS bios9.bin, 4KB: ARM9 BIOS firmware.bin, 128/256/512KB: firmware El arranque del firmware requiere un volcado del firmware de una DS o DS Lite original. Los firmwares de DS volcados desde una DSi o 3DS no son arrancables y sólo contienen datos de configuración, por lo que sólo son adecuados para arrancar juegos directamente.
Posibles tamaños del firmware:
128KB: DSi/3DS DS-mode firmware (reduced size due to lacking bootcode) 256KB: regular DS firmware 512KB: iQue DS firmware Los volcados de BIOS de DSi o 3DS pueden utilizarse sin problemas de compatibilidad. Los volcados de BIOS de DSi (en modo DSi) no son compatibles. O tal vez lo sean. No lo sé.
Por lo demás, la interfaz debería ser bastante sencilla. No obstante, si tienes alguna duda, no dudes en preguntar.
