## Where to put the games

Playstation 2 games should be put under the `retrodeck/roms/ps2/` directory.

PCSX2 supports the following formats: `ISO` `BIN with CUE files` `CHD`


## Does Ryujinx require BIOS or Firmware?

Yes, they need to be put directly into the `retrodeck/roms/bios/` without any subfolder.


## How to enable/disable Multitap?

Multitap is a way to have up to 8 players on the Playstation 2, by hooking 4 players in each controller port.
