X-Men free play

[KalessinDB]

Has anyone used this hack? I'm just curious about specifics on it, since they're the only site I've seen providing it, and they have precious little information listed.

By specifics I'm thinking: still possible to turn off free play? Does attract mode still run? What roms am I burning and replacing? Etc etc

I think one circuit (YouTube channel) sells a board for free play. I saw it on his channel.
