Firmware / BIOS files

Some games require a firmware file (sometimes called a BIOS). Whenever a game that requires a firmware file is loaded, the emulator will automatically prompt you for the file. All firmware files are saved in the Firmware folder.
The following firmware files are used:

BS-X/Satellaview: For BS-X/Satellaview games, the BS-X cartridge’s firmware is required. It is stored under the name BS-X.bin.
DSP: This family of enhancement chips is used in a fairly large number of games, and several variations of the chips exist, each requiring their own firmware files. The split file format used by bsnes/higan is also supported, e.g: dsp1.data.rom and dsp1.program.rom.
dsp1.rom: DSP-1
dsp1b.rom: DSP-1b
dsp2.rom: DSP-2
dsp3.rom: DSP-3
dsp4.rom: DSP-4
st010.rom: ST010
st011.rom: ST011
Game Boy: For Game Boy and Game Boy Color games, the boot roms are optional. When the files are not found, the open source GB/GBC boot roms written by LIJI32 (SameBoy author) will be used instead.
dmg_boot.bin (256 bytes): Game Boy Boot ROM
cgb_boot.bin (2304 bytes): Game Boy Color Boot ROM
Super Game Boy: SGB emulation requires the SGB’s ROM. Several versions exist based on region, and a different SGB2 ROM is also required for the SGB2.
SGB1.sfc (256 kb): Super Game Boy
SGB2.sfc (512 kb): Super Game Boy 2
sgb_boot.bin (256 bytes): Super Game Boy CPU Boot ROM (optional)
sgb2_boot.bin (256 bytes): Super Game Boy 2 CPU Boot ROM (optional)
