Arcade: Midway MCR

Start with: midssio.zip.

How to read a card

A card gives the file's fingerprints, the emulators that read it, the setups that list it and where to download it. A file can have several versions, one per region or revision: the main one comes first, the others under "Variants". To install the files of one console, open its "Install" box.

On the setup's list names the setups whose own BIOS list has the file, by the name each gives it. Packed for its emulators by names the setups whose pack adds it because one of their emulators reads it.

MAME and FBNeo sets must match the emulator's version. Which version each core reads.
