## BIOS 
This BIOS is optional if you want the Atari Logo at the beginning of games, otherwise you don't need it because the games work fine without it. The BIOS file name is **7800 BIOS (U).rom**

Note: if this BIOS is enabled, PAL ROMs will not work so use it accordingly.

## Controls

lr-prosystem utilises Retroarch configurations

Add custom retroarch controls to the retroarch.cfg file in
```shell
/opt/retropie/configs/atari7800/retroarch.cfg
```
For more information on custom RetroArch controls see: [RetroArch Configuration](RetroArch-Configuration)
