I've been downloading some GBA roms, and transfered onto a R4 card with system files and I try to play them and I get the message This types of files currently not allowed to operate. Do I have to download different system files to the DS?
you need to get a flashcart for the GBA Slot(Slot 2), not for the Slot 1 (DS Slot), from what i'm hearing and reading its impossible to do it on the Slot 1 for some info about a ton of crap which is mostly techno linggo so....yeah. :-X
iplayer can play them, but check out this message by me - https://www.romulation.org/forum/index.php?topic=28007.msg476069#msg476069 https://www.romulation.org/forum/index.php?topic=28007.msg477479#msg477479 you will need a slot two gba flash cart. there is the ez flash 3 in 1, the ez flash iv if you can find it, and some other ones that are pretty good. i recommend the ez flash 3 in 1. but i have the ez flash iv which is pretty good too.
