Mentioned this before, but I just received, once again, Mr Gimmick on NES, as a reproduction cart from retrousb.com... the first time they sent it to me it didn't work... then it took about 2 weeks to get their mailing address to send it for repair, then they took them over a month to repair it, but now it works and it's pretty badass. Quite surprising graphics/physics-wise considering it's an NES game.
Now to figure out how to input this in my collection since it's a repro. "Unofficial release", or "Unreleased"?
