AOS is a multi-loader for Ace3DS and related carts.

This repository aims to re-pack the official AOS software by ace3ds.com with new and updated homebrew apps; it is in no way affiliated with ace3ds.com.

The following carts can be either an Ace3DS or an R4iLS:

• XXX in 1 carts
• Unlabeled carts with a red PCB - (Image)
• Flashcarts labeled as a game - (Image)

If you have one of these carts, you will need to grab an empty SD card, insert it into the cart, and boot the cart on your DS.

• If you get a missing _DS_MENU.DAT error, you need the Ace3DS package.
• If you get stuck at a loading screen, or get a missing _DSMENU.DAT error, you need the R4iLS package.
• If you get a MENU? screen, you have a DSTTi timebomb clone and can't use AOS. These carts use YSMenu.

1. Identify your cartridge and choose the correct package version based on the supported carts list above.
2. Download the appropriate .zip file for your cart from the releases page.
3. Extract and copy the contents of the zip file to your flashcart's SD card root.
4. A lot of the emulators included in this package require a BIOS file, or can use one to improve compatibility. You can obtain the BIOS files for each emulator and place them in the appropriate locations, like so (expected file name is in parentheses):

• BIOS Required for Use

  • GBARunner3 - (bios.bin) - /_gba
  • ColecoDS (coleco.rom) - /roms/bios

• BIOS Optional, but Highly Recommended:

  • A8DS (atarixl.rom, atariosb.rom, or ataribas.rom) - /roms/bios
  • A5200DS (5200.rom) - /roms/bios
  • A7800DS (highscore.rom - for 7800 High Score saving) - /roms/bios
  • GBARunner2 (bios.bin) - /_gba
  • GameYob (gbc_bios.bin - provides color in GBC titles) - /roms/gb/
  • S8DS - See GitHub ReadMe, multiple BIOSes supported.

• While GBARunner2 will work without a BIOS, GBARunner3 will not until one is placed in _gba. Be sure to add a GameBoy Advance BIOS before using it.
• JenesisDS requires ROMs to be in .gen, .bin, or .smd format to be recognized in the file browser. If you have .md ROMs, rename them to .gen or .bin before placing them in /ROMs/gen on your SD card.
• NeoDS requires ROMs to be converted to .neo format before they can be used. See this README before using.

0. You must be on Linux
   • WSL2 works. MSYS2 (provided by devkitPro) probably also works, but no guarantee is provided
1. Set up devkitPro's NDS environment
2. Run ./build.sh
3. Individual kernel files will appear in out folder

• Ace3DS: AOS 2.13, Wood kernel
• All external application developers as seen in above list
