I've done alot of research to find a patch that would allow someone to play certain courses online that you previously could not. After trying and applying multiple different patches, I just came across the only patch to not give me two white screens when I start. http://www.darknovagames.com/Hx0r/index.php?page=download for the IPS Patch I have also patched a rom with Crackers trainers. I was just wondering if anyone else knew of ANY other MarioKart DS hack, glitch, patch, or trainer. Anything at all.
