I am thinking of purchasing a supercard + superkey but i need to clarify some things first. Firstly, the main reason i bought the ds lite was to play with other people all around the world using my house's wifi connectivity. If i purchase the supercard + superkey and use downloaded roms off the internet (e.g metriod and mario kart), will i still be able to play with people around the world using wifi? If they are using legit games, will i still be able to play with them? Ive read on several forums that if u want to play with your friend beside u, he must have a flashed ds in order for both people to play wirelessly, however, now im enquiring on using wifi to play globally and i dont care about playing with friends nearby. Secondly, i only want to play DS games on my DSL so is it wise to get a supercard mini sd because i heard that m3 is faster and supercard have slowdowns in some games. I am planning to buy an ATP 150X 1gb mini sd card and want to know if this cures the slowdowns in games when using the supercard. On a side note, how many games can a 1gb mini sd card hold? I hope you guys can answer my queries so that i can make my decision soon.
