This Mega Everdrive Pro is an awesome piece of hardware. In addition to playing Megadrive roms, it also plays Virtua Racing (the only SVP game ever made), Sega Master games with FM support (for those compatible games) and Mega CD games. Also, so called MSU (aka Mode 1) patched games work flawlessly. More info about MSU here.
Highly recommended piece of hardware, no more having to mess with aging hardware, just fire up your Genesis / Megadrive console and you’re good to go.
