A few years ago I was looking at GB/C flash carts and the only ones that existed were really old and expensive on eBay. So I was surprised to see that there was a flash cart available today and it uses something that doesn't require a battery for saves. $100 is a lot, and it only holds one game at a time (with the cartridge acting like a flash drive that you can drag games into), but if it plays all the games then I think it could be worth it, all the pokemans to link up with pokeman stadium and such. But if it doesn't play all the games, or at least lots of the good ones/classic ones then $100 seems steep. I can't find a compatibility list though. I've read that it will run MBC5 games of 3mbyte or less, and some MBC1, but I don't really know what that means. I could totally see myself buying a couple of these if they work, with keeping a different folder structure on my computer for each, so then I can do pokeman battles.
