melonDS-Vita

Vita port of MelonDS emulator

The source code is provided under the GPLv3 license.

How to Use

melonDS requires BIOS/firmware copies from a DS. Files required:

bios7.bin, 16KB: ARM7 BIOS
bios9.bin, 4KB: ARM9 BIOS
firmware.bin, 128/256/512KB: firmware

Firmware boot requires a firmware dump from an original DS or DS Lite. DS firmwares dumped from a DSi or 3DS aren't bootable and only contain configuration data, thus they are only suitable when booting games directly.

Possible Firmware Sizes

128KB: DSi/3DS DS-mode firmware (reduced size due to lacking bootcode)
256KB: regular DS firmware
512KB: iQue DS firmware

DS BIOS dumps from a DSi or 3DS can be used with no compatibility issues. DSi BIOS dumps (in DSi mode) are not compatible. Or maybe they are. I don't know.
