I cant find anything like my situation... I have a ND i that I bought used, I have multiple GBA & NDS game programs on my computer and none will load in my system. I tried putting them on a micro sd card and put that in one of the R4, when that didnt work I put it in a sd card, still didnt work. tried emailing them to myself and downloading from the internet part. Still didnt work. Most of the program extensions are either GBA or NDS I tried looking for something different to convert into, couldnt find anything... HELP! PLEASE?! OH I also will be getting a DS Lite very soon. can anyone lead me in the right direction for those conversions if possible too? Please?
