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](https://docs.libretro.com/guides/bios/), just search for your core.
|
||
|
|
More info by clicking on the system name down here.

[PPSSPP](https://docs.libretro.com/library/ppsspp/)<br/>
|
||
|
|
Starting everything should be included. <br/>
|
||
|
|
But if you want the original PSP fonts you can place them in `system/PPSSPP/flash0/font`

Content of [blueMSXv282full.zip](http://bluemsx.msxblue.com/download.html).<br/>
|
||
|
|
Not the zip itself, its contents must be extracted in `~/retrodeck/bios` folder, more info [here](https://docs.libretro.com/library/bluemsx/#bios).
|
||
|
|
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
|
||
|
|

|

├── other 217 files...
|
||
|
|
└── fd0d23003ea5602c24ac4e41101c16fd.nca
|
||
|
|
```
|
||
|
|
|
||
|
|
You can find a complete guide in the [Yuzu official wiki](https://yuzu-emu.org/help/quickstart/#downloading-and-installing-yuzu) 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](https://www.lexaloffle.com/games.php?page=updates) 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:<br/>
|
||
|
|
- `~/retrodeck/bios/bios9.bin`<br/>
|
||
|
|
- `~/retrodeck/bios/bios7.bin`<br/>
|
||
|
|
- `~/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.
|
||
|
|
|
||
|
|
## PCSX2 (PS2)
|
||
|
|
|
||
|
|
There a multitude of PS2 bios for a complete list with the hashes check <br>

|
[Gametechwiki](https://emulation.gametechwiki.com/index.php/File_hashes#Known_BIOS_Hashes)
|
||
|
|
|
||
|
|
The PS2 bios could be named in the following ways
|
||
|
|
<br>
|
||
|
|
By bios version: `ps2-0200a-20040614.bin`
|

|
<br>
|
||
|
|
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`.
