RetroDECK/wiki-rdd/Emulators:-BIOS-and-Firmware.md

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.

RetroArch (Libretro)

Some cores may need some BIOS files to work or run correctly. Here are the most common systems, if you find more we can add them to this wiki. However the extended information can be found on the official libretro documentation, just search for your core. More info by clicking on the system name down here.

*only required for a specific game

PPSSPP
Starting everything should be included.
But if you want the original PSP fonts you can place them in system/PPSSPP/flash0/font

MSX / SVI / ColecoVision / SG-1000
Content of blueMSXv282full.zip.
Not the zip itself, its contents must be extracted in ~/retrodeck/bios folder, more info here. Starting from v0.5.0b this is automatically provided.

Yuzu

Yuzu needs the key files prod.keys, title.keys and the firmware files in the following directories:

Yuzu keys: ~/retrodeck/bios/switch/keys

Yuzu firmware: ~/retrodeck/bios/switch/registered

The directory tree should look like this example:

~/retrodeck/bios/switch
├── keys
│   ├── prod.keys
│   └── title.keys
└── registered
    ├── 02259fd41066eddbc64e0fdd217d9d2f.nca
    ├── 02582a2cd46cc226ce72c8a52504cd97.nca
    ├── 02b1dd519a6df4de1b11871851d328a1.nca
    ├── other 217 files...
    └── fd0d23003ea5602c24ac4e41101c16fd.nca

You can find a complete guide in the Yuzu official wiki on how to extract the BIOS from your Switch.

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 image, free of any copyrighted content, and only containing a dummy dashboard. So if you want to the complete experience you have to provide your own.

Usually those files are dumped/found as:

mcpx_1.0.bin
Complex.bin -> Complex_4627v1.03.bin or Complex_4627.bin
xbox-eeprom.bin -> eeprom.bin
xbox_hdd.qcow2 -> xbox_harddisk-D4920.qcow2

So don't forget to rename them for the RetroDECK standards.

PICO-8

Pico-8 it's not freeware hence it cannot be included with RetroDECK, however it's supported by using these steps:

1. Download PICO-8 for Linux 64-bit from the official website or where you bought it.
2. Extract the zipfile somewhere on your desktop
3. Copy the content of the extracted pico-8 folder into ~/retrodeck/bios/pico-8/

MelonDS (Standalone), (NDS)

MelonDS by default needs those files:

• ~/retrodeck/bios/bios9.bin
  
• ~/retrodeck/bios/bios7.bin
  
• ~/retrodeck/bios/firmware.bin

However there is a setting to disable the need of these files by going to: Tools -> Start MelonDS -> Yes -> Config -> Emu settings -> DS-mode and removing the check on Use external BIOS/firmware files. Please be advised that this operation may prevent the games from running correctly.
