okay.. i might go to gamecrazy and buy a guitar grip but only if it works with acekard 2.. i used to have the guitar hero bundle, but i sold it.. but first... 1. is there any incompatability issues? i plan on finishing all guitar heroes, and some others like rock band and maybe band hero.. 2. what accessory does lego rock band require? band hero? 3. is there a list for all music games on the ds? (only looking for quality ones) thanx guys! also, i need a new stylus, does gamecrazy sell them cheap?
