I downloaded Guitar Hero and GTA, and both dont load correctly! GTA says "the save data could not be processed. please turn the power of and reinsert the ds card" still doesnt work. and guitar hero says "you cant rock without a guitar hero guitar grip! turn off the power and insert the guitar grip" wat? OOPS, i forgot to mention this is for THE NINTENDO DS, THE R4.
GTA - you do not say which card you have, however there is a patched rom which works with most cards - you will have to search for it. If you have a supported card - look for the latest firmware in my signature - most now have updates to inc this. Guitar Hero - where have you been?? - Guitar hero needs a grip to have the buttons on - you can but them seperately from dealextreme.com for a few dollars (free shipping) - be careful if you have a phat as most do not support this model
Guitar Hero - You can play the game without the grip, by using XYBA instead, look on gbatemp.net for instructions. I've played the first Guitar Hero using this method, but its not fun.
