aizen92 wroteYes, I intend to play DS games only on it.
I have a couple of questions also.
1- While playing DS games, do I have access to the internet?
2- Can I play DS games online using R4i? Like Pokemon?
3- Someone told my brother that if I used R4i once, I won't be able to access the internet on the console at all, is it true?
4- If I used the R4i card and played DS games, will I be able to play 3DS games online again?
5- Can I play online if I get original DS cards?
Only thing I know is that you better NOT update your firmware if you use a flash card. Updates can render flash cards unusable. If no one can answer your questions here, I suggest you ask at gbatemp.net.
