Nintendo DS & DSi · Emulators on DS

1. For TWiLight integration, install its Virtual Console add-on, then copy nesDS.nds to /_nds/TWiLightMenu/emulators/.
2. Keep your own NES/FDS games separately; back up the existing emulator before replacing it.

Use the flashcart-compatible .nds asset for flashcarts. The .dsi variant adds a DSi title identity for compatible DSi launch/install routes. The extension alone does not set the CPU mode. The CIA asset belongs to a separate 3DS installation format and is excluded here.

Famicom Disk System games additionally require your own disksys.rom BIOS at the SD root.

1. Place gameyob.nds in a folder such as /roms/nds/homebrew/. Choose gameyob_dsi.nds only for a launcher with DSi-mode support.
2. Create /_nds/ at the storage root; this release saves its settings there. Select your own GB/GBC games in the emulator.

Use a launcher with working DLDI/storage access. The release notes acknowledge remaining Super Game Boy palette issues.

1. Extract NitroGrafx.nds and launch it through your homebrew menu. Create /NitroGrafx/ or /data/NitroGrafx/ for settings and saves.
2. Keep your games in a folder of your choice. For CD titles, select your own System Card BIOS in Options → Machine → Select Bios and follow CDROM_readme.txt.

Some flashcarts need DLDI patching. No SuperGrafx emulation; game and CD compatibility varies. Published build is 0.9.1 even though the main-branch README says 0.9.2.

1. Extract S8DS.nds. Create /S8DS/ or /data/S8DS/ for settings and saves.
2. Place your own games and any system-specific BIOS files in a folder of your choice, then select them in the emulator.

Storage access may require DLDI patching on older flashcarts. Some emulated systems require a BIOS; compatibility varies. This is release 1.1.8, rather than the newer README version.

1. Copy A7800DS.nds to your card and launch with TWiLight Menu++ or Unlaunch on DSi, or a homebrew-capable flashcart.
2. Optional game folders: /roms/a7800/ or /roms/a78/. An optional 4 KiB BIOS named 7800.rom goes in /roms/bios/, /data/bios/ or beside the emulator.

Use your own .a78/.bin games. The published build supports NTSC; PAL is unsupported. DS/DS Lite has less CPU headroom than DSi; do not assume identical performance.

1. Copy StellaDS.nds to your flashcart microSD or console SD and launch it. Tap the cartridge slot to select your own .bin/.a26 game.
2. Configuration and save data are created under /data/. Keep those files when updating.

Advanced DPC+/CDF cartridge types need DSi-class hardware running at 134 MHz for the intended experience. A flashcart normally runs in 67 MHz DS mode, including on a DSi/3DS. Older launchers may need DLDI patching.
