I've recently acquired one of these and most of the roms that I suspected would be trouble work like a charm, but others do not. In particular, I'd like to make the Classic NES Series games not say "Game Pak Error -- Turn the Power Off" (and the Famicom Mini series seems to return the same error, only in Japanese). I know this is a known issue, so please forgive my noob question, but the old threads I've found on this either say to patch them but don't say with what, or have dead links to patches or fixed roms. I do have GBATA, but I'm not sure what I need to do with it, or if I need another utility. I also get a black screen when trying to load Yoshi's Island, another game that I know has been made to work with these, but I'm not sure what to do with it. Also interested in more general advice as far as what to do with roms that don't play nice. Thanks!
