I had a ds lite years ago and played many, MANY games using my acekard 2.1 with the latest akaio firmware. I sold it, moved on, and now Im back craving more portable gaming. I bought a new 3ds XL a month ago, and performed an update in order to access the e-shop. Now I wanted to play some ds games on it, and reading here I came to the conclusion that the dstwo is THE card to have. Is there anything I can do in order to use it with my current firmware? Maybe I could format the console to factory settings? The thing is that I don't want to do this, because Im not sure what else I will be deleting in the process besides the firmware. I haven't bought and/or downloaded any game, rarely use the apps it the 3ds comes with pre-installed ... basically I just use it to play ocarina of time 3ds. Eventually I would like to play mk7 online and maybe buy some 3ds games from the e-shop ( for convenience ), but Im concerned I may get banned or something. Or since the dstwo wont be inserted, then the system will just work as normal? Thx in advance for your help.
