I havent been too involved with the scene since the DSi came out, so hopefully this isnt a silly question. Ive been trying to look for help but this must be an obscure cart of some sort. http://r4i-u.com/products.asp down where it says 'R4-2 Silver' That is my cart, im just trying to figure out what firmware it clones off of (DSTT,AK2 etc..). I would like to be able to install an alternate firmware but have had no luck. If anyone could help me a bit with this card that would be great.
