Welcome jimagine21,
I'm also interested in SuperNintendo and Megadrive cartmod. I already have some supernintendo and megadrive repros for my collection.
I have several spanish translations of japanese games (Secret of Mana, Chrono Trigger, and many more).
Now I'm intersted in multi-game cartridge.
It could be interesting to make "Disney recopilation" or something like that. :-P
See you!
