Hacking R4i Gold Issues

[Swaggie1]

aye there, I got a r4i gold a couple months ago, and i've been trying to figure out a couple of things :

Golden Sun Dark Dawn gives me black screens, and with eur rom gives me "deleting game cartridge information"

And Kingdom hearts re - coded gives me white screen

flashcart say r4ids.cn in front

I have tried clean roms, fixed roms, formatting my sd card and nothying works

Any help :}?
