FM Towns MArty compatibilty list

I second that. Really useful indeed, but you have to search using the game title's kanji name.

I also like visiting this page, Ruins of FM.
Has tons of infomation & screenshots of games on the FM-Towns and FM-7.

 

This place has lots of freeware and shareware stuff.

I can't see any dodgy isos (ie normal) there but if I'm mistaken let me know and I'll edit the link out..I don't condone that behaviour at all.
