Homebrew DS(i) Mode hacking progress thread

[admin]

This thread is for talking about advanges of the DS(i) gaming on the 3DS, suggestions and telling what is possible with this are very welcome

@TuxSH just made a Tool to read/write saves from DS cartridges, and this is pretty amazing, because there wasn't a method to at least touch the TWL_FIRM and this is just the first step of DS(i) mode hacking.

3DS Mode tools:

1. Manage saves from DS cartridges using TWLSaveTool.
2. Dump .nds roms using GodMode9.
3. Install DSiWare save data exploits using 3ds_dsiwarehax_installer.

Please fill out this list.

What is possible to do with DS(i) Mode at the moment?

1.- Run SRL unsigned code and run all DSi compatible Flashcards (Use Luma3DS):

2.- Run old R4s (not all) thanks to @Apache Thunder 's TWL Slot-1 Launcher.

3.- Run some "Download Play" DS demos. You can search for them on the Internet.

4.- Use Stage 2 Launchers to run directly a .nds/.dat from a flashcard bypassing cartridge checks, thanks to @Apache Thunder, and this inspired @Robz8 to create game forwarders that install directly into TWLNAND and load the game that's in the flashcard, modifing the .ini file to autoboot the game that you want to run, or load the game that's in the 3DS SD Card:

- Stage 2 Launchers: https://gbatemp.net/threads/r4-stage2-twl-flashcart-launcher-and-perhaps-other-cards-soon™.416434/
- NTR Launcher (run games/flashcards with DS/DSi boot screen): https://gbatemp.net/threads/ntr-lau...ssic-ds-boot-screen-for-your-ds-games.440110/
- NTR Launcher 3D (same as above, but the boot screen is in 3D and 240p): https://gbatemp.net/threads/ntr-lau...s-boot-screen-for-your-ds-games-in-3d.474979/
- NDS Forwarders (works with homebrew & DLP games too): https://gbatemp.net/threads/nds-forwarder-cias-for-your-home-menu.426174/

5.- DSi HBL, no need for Sudokuhax anymore:

6.- Unlock SD access into the NTR mode (DS).

7.- Run old DS homebrew (that use DLDI) from the SD card.

8.- Loading commercial/retail ROMs from SD Card, including save redirection.

• nds-bootstrap (by @ahezard)

9.- 48kHz sound in DS games.

Frontends for nds-bootstrap:

• https://github.com/ahezard/nds-hb-menu (outdated, and not recommended)
• TWiLight Menu++: A recreation/replacement of the original DSi Menu, and works on DSi, 3DS/2DS, and flashcards.
• RocketRobz (aka @Robz8)'s DS forwarders.

And a lot of interesting things that you could find on @Apache Thunder's YT Channel:

Not WIP, but what has been found out?

• DS injection on DSiWare titles (this is being possible by patching the game's header and other things, but we are limited to TWLNAND's poor size, however, @Robz8 found a way to trim roms to fit more-or-less into TWLNAND, see here: https://gbatemp.net/threads/ds-i-mode-hacking-progress-thread.413015/page-67#post-6302143 ).

What is in WIP?

• DSi mode support for nds-bootstrap.

A lot of users says "get a pesky cheap flashcard", but a lot of those flashcards lacks of features like: IR, Wii Connection (Pokemon Battle Revolution), WPA Wi-Fi and DSi Enhanced enable. The possibilities to get a full control of the DS(i) Mode are a lot, just think about getting a enhanced DS(i) Mode experience.
