Myrdin> Golden Sun is a such good game... I can' ttell how many time I played and replayed it. Both of them. You can play it on emulator and still keep Golden Sun 1 data by using the damn password. It's a fucking ridiculous long password which don't allow you any mistake (if you doyou can just delete all the stuff after the mistake) but you can use any save from any Rom or actual cartridge.
Golden Sun 2 is really good. Maybe better than the first one on some point.
