OrbisPro does NOT provide BIOS files, so you will need to add them manually using the File Explorer.
Firmware files are also NOT included but can be downloaded & installed within OrbisPro.
For PS1 games, place your BIOS files into "System\Emulators\ePSXe\bios"
For PS2 games, place your BIOS files into "System\Emulators\PCSX2\bios"
For PC-Engine games, place your SYSCARD*.PCE files into "System\Emulators\mednafen"
Open the File Explorer and go to the folder where the BIOS file is located
Select the copy action and open 'System' on the left menu
Navigate to the corresponding folder (see list above)
Paste the BIOS file into this folder using Triangle/Y or A on the keyboard

Deleting the wiki page "BIOS Files Installation" cannot be undone. Continue?
