Famicom mini is the japanese name for the NES classics. There's some kind of hack to make them work, where you copy the game 4 times into a single file to make it the right size (or something like that). It's not something that most people could do though, so you'll just have to wait/look around for someone to make a "fixed" version of the rom.
...your best bet though would be to simply find the original famicom version and a famicom emu.
