Emulating it today

EmulatorsmelonDS, DeSmuME
Setup effortTrivial to run (1 on this site's scale)
ControlsThe original interface uses a touch screen, so a modern touch device is the closest match.
Runs on a handheldYes

Handled with high speed by melonDS and DeSmuME cores. Touchscreen maps cleanly to mouse, stylus, or right analog stick, with customizable dual-screen screen layouts. The emulator names above are starting points, not a promise that every title or accessory behaves identically. Computer platforms usually add model selection, disk handling and keyboard setup even when CPU emulation itself is mature.

Nintendo DS BIOS & Firmware (bios9.bin, bios7.bin, firmware.bin)

The Nintendo DS utilizes two CPU boot ROMs (ARM9 and ARM7) alongside a 256 KB or 512 KB firmware chip holding the user profile, calibration data, and system menu. While emulators like melonDS and DeSmuME include built-in high-level BIOS replacements for basic games, dumping the real BIOS and firmware files is required for full compatibility, DSi software, and authentic boot behavior.

How many files you need: 3. Three files: bios9.bin (ARM9 CPU BIOS, 4 KB), bios7.bin (ARM7 CPU BIOS, 4 KB), and firmware.bin (system configuration and menu, 256 KB).

Firmware details checked 2026-08. Emulator requirements change — see Libretro — melonDS core documentation for the current list.

Where the software is
