How to: Manage BIOS and Firmware
A BIOS or firmware is like the brain of a computer or electronic device. It helps the device start up and makes sure all its parts work together smoothly. In emulation, having the correct BIOS/firmware is important because it allows the software to pretend to be the real device and work properly.
That's why some emulators require BIOS and Firmware files to work correctly or at all.
Generally the bios files should be put in ~/retrodeck/bios
but there could be exceptions to this.
RetroArch (Libretro)
Some cores may need some BIOS files to work or run correctly. Official Libretro BIOS Guide
Ryujinx / Yuzu (Legacy)
Needs the key files prod.keys
, title.keys
and the firmware files in the following directories:
Keys: ~/retrodeck/bios/switch/keys
Firmware: ~/retrodeck/bios/switch/registered
The directory tree should look like this example:
~/retrodeck/bios/switch
โโโ keys
โย ย โโโ prod.keys
โย ย โโโ title.keys
โโโ registered
โโโ XXX amount of .nca files goes here
Ryujinx also need it's firmware installed.
XEMU (Xbox)
These files must be placed with the correct name in the given folders:
~/retrodeck/bios/mcpx_1.0.bin'
~/retrodeck/bios/Complex.bin'
~/retrodeck/saves/xbox-eeprom.bin'
[OPTIONAL] ~/retrodeck/bios/xbox_hdd.qcow2'
The hard disk is optional as RetroDECK already provides a pre-built 8G Xbox HDD empty image with a dummy dashboard.
MelonDS (Standalone)
MelonDS needs the following files:
PCSX2 (PS2)
There a multitude of PS2 bios for a complete list with the hashes check
The PS2 bios could be named in the following ways
By bios version: ps2-0200a-20040614.bin
By system name:SCPH-70012.bin
Put the bios inside the bios folder: ~/retrodeck/bios/SCPH-70012.bin
Here is a list of common used bios with bios versions/system names/hashes
.
ps2-0200a-20040614 - SCPH-70001/SCPH-70011/SCPH-70012 - d333558cc14561c1fdc334c75d5f37b7 -PS2 US BIOS
ps2-0200e-20040614 - SCPH-70002/SCPH-70003/SCPH-70004/SCPH-70008 - dc752f160044f2ed5fc1f4964db2a095 - PS2 EU BIOS
ps2-0200j-20040614 - SCPH-70000 - 0eee5d1c779aa50e94edd168b4ebf42e - PS2 JP BIOS

NeoGeo
neogeo.zip
Should go into the ~/retrodeck/roms/neogeo/
folder and the ~/retrodeck/bios
folder. Depending on what emulator you use, the emulator looks for the BIOS in different directories. So the safest way it to just copy the BIOS and put it into both places.
Apple II
For Apple II the following bios needs to exist in: ~/retrodeck/roms/apple2/
Apple IIGS
For Apple IIGS the following bios needs to exist in: ~/retrodeck/roms/apple2gs/
