notes: |
|
|
MelonDS includes a built-in FreeBIOS replacement for basic DS mode (NTR).
|
|
Native BIOS/firmware files are required for DSi mode and recommended for
|
|
full DS compatibility (Key1 crypto for cartridge auth).
|
|
ARM9 BIOS size: 0x1000 (4 KB), ARM7 BIOS size: 0x4000 (16 KB).
|
|
DSi BIOS size: 0x10000 (64 KB) each.
|
|
Config keys: DS.BIOS9Path, DS.BIOS7Path, DS.FirmwarePath,
|
|
DSi.BIOS9Path, DSi.BIOS7Path, DSi.FirmwarePath, DSi.NANDPath.
