I'm about to get my O3DS back from having it hard modded (courtesy of one of the guy's of GBA Temp...thank you so much). Up until a few days ago all I done was use a flashcart to play ds roms, however, I would really like to play GBA games and everything else I can. I have been searching around for a few days now trying to get information what actually A9LH does. As a n00b to the whole modding and hacks etc I am so confused. Everything I have looked at is talking about emunand and sysnand and all sorts of stuff that I don't understand and can't find the information that I clearly need. I was wondering if you good people can help or if there is anything on here that is a 1 stop shop so to speak on all of the information needed for a total n00b like me?
