Im more scared to update my R4I.SDHC 3DS(wich is basicly a R4I-SDHC but putting the 3ds patch on so it works on the 3ds too.)I need to update it due to some of the purchase's when the new Pokemon game comes out.Im gonna wait untill someone tests this.
Untill i work out how to work TTDT for the number use a program to insert 2.narc and 3.narc into a japanese rom-that's what im doing and its working fine(execpt an insistant trainer on route 4 who allways battles you:P)
