Specific system information

Multi-disc

You can use a m3u file to manage multi-disc games.

For example for Alone In The Dark, if the ROM contains the following files:

create a Alone in the dark The new nightmare.m3u text file with the following content and save it to the /roms/dreamcast folder:

Retrobat will automatically detect the m3u file and hide the individual .gdi files from the Game List.

Custom textures can be used with the flycast core.

The texture pack must be placed in the \bios\dc\textures\ folder:

Then, enable CUSTOM TEXTURES in ADVANCED SYSTEM OPTIONS or in ADVANCED GAME OPTIONS.
