Hi, I am a newbie. I just bought a DS Lite (US version). and my brother got me the R4 from HK. The box is in chinese. I don't know if that is the problem. But when I put the R4 with the memory card and the required files, the DS Lite will freez with a 2 white screens. Any idea? Is the card busted or there is some incompatible between the 2 devices? Please response, thanks.
