Bios Information

Depending on the romset type, a BIOS can be required or not to play some games:

• Full non-merged: the BIOS is included in the ROM file, so no BIOS file will be needed

• Non-merged: same as "Full non-merged" but BIOS that are shared by multiple games are placed outside of the individual ROMs

• Split: BIOS files are required

• Merged: BIOS files (as well as multiple versions of the game) are placed inside the ROM, no separate BIOS is required

Refer to the Arcade page for more information about ROM set types.

Here is a non-exhaustive list of MAME bios files (based on rom set 0.255):

2MB

MAME 0.255 ROMs (bios-devices).xml

BIOS files must be placed at the root of the \bios folder of your RetroBat installation.

Known issues & fixes

I only get a black screen when running games with libretro:mame core

Libretro:Mame has a limitation in the length of the paths it uses when launching a game through command lines. This limitation does not exist with standalone Mame.

In order to be able to fix this issue, ensure that your RetroBat folder path does is not installed in a path that is too long.

For example the path C:\Emulation\Multi Emulators\FrontEnd\All-in-one\This is top\RetroBat version 6.3 is too long and will result in the issue.
