  • 追求高兼容性的模拟器爱好者
  • 对将 Android ARM64 代码移植到 Switch 感兴趣的开发者
  • 寻找便携 DS 游戏方式的复古玩家

典型使用场景

  • 在 Switch 上运行任天堂 DS 游戏
  • 使用自定义着色器和滤镜增强视觉效果
  • 利用 Slot-2 外设如 GBA 卡带或震动包
  • 通过外接耳机利用麦克风输入完成 DS 游戏的要求

README 快速开始

Drastic DS · Switch Port

A native wrapper/port of Drastic DS Emulator to the Nintendo Switch. It loads the original Android ARM64 emulator core libdrastic_arm64.so, patches it, and runs it inside a minimal Android-like environment natively.

Everything ships as a single DrasticDS.nro: it bundles the build-supplied Drastic core, game database and cheat table, both renderer backends (OpenGL + Vulkan/NVK), 17 ready-to-use custom shaders, and an SDL cover-art launcher. Nintendo DS BIOS and firmware are never packed into the NRO.

How to install

  1. Copy DrasticDS.nro into /switch/ on your SD card.
  2. Copy your own Nintendo DS system dumps into /switch/drastic/system/:
    • nds_bios_arm7.bin — 16 KiB ARM7 BIOS.
    • nds_bios_arm9.bin — 4 KiB ARM9 BIOS.
    • nds_firmware.bin — 256 KiB firmware.
  3. Put legally obtained .nds, .zip, or .rar games in /switch/drastic/games/, or add another SD, USB, or SMB library folder from Settings > Library & storage.

The launcher creates the rest of the folder tree and extracts the selected renderer and bundled application resources on demand:

/switch/DrasticDS.nro
/switch/drastic/
  .emu/                   .png)
  forwarders/              Controller**.

### Microphone input

Choose **Settings > Audio > Microphone source** before launching a game, or
change it at runtime from **Audio, input & motion** in the in-game menu.
**Simulated noise** retains the microphone hotkey for games that only require
blowing. **External microphone** captures real audio from a CTIA-compatible
headset connected to the 3.5 mm jack or a compatible USB audio input. Attached
USB inputs are preferred automatically, and reconnecting or unplugging a
device is handled while the game is running. Bluetooth microphone input is not
supported by Nintendo Switch.

### Slot-2 accessories

Choose the accessory before launching a game under
**Settings > Gameplay / Features > Slot-2 accessory**. The complete native
Drastic set is available: None, GBA Cart, SRAM Cart, Rumble Pack, Motion Pack
(Official), and Motion Pack (Homebrew).

For GBA Cart, put the GBA ROM and its raw cartridge save in
`/switch/drastic/slot2/`. Name them after the DS ROM (for example,
`Pokemon Platinum.gba` and `Pokemon Platinum.sav` for
`Pokemon Platinum.nds`). `slot2_gamepak.gba` and `slot2_gamepak.sav` can be
used as the shared fallback pair.
