: You must use a modified Genesis Plus GX core (often referred to as the "Paprium" or "ETH" core). Standard cores will usually get stuck on the initial "mini-game" or "retro stage". File Structure : Place the Paprium.bin ROM in a dedicated folder.

However, for the retro gamer simply wanting to play the best beat-’em-up on the Sega Genesis without a mortgage payment, the ROM is the only viable path.
