Hey guys. I'm trying to patch my Mario Kart ROM to allow the hidden tracks (such as Tick Tock Clock) to be played in wifi mode. Unfortunately, the game whitescreens on both hardware and emulators after patching. I'm using a clean ROM with a CRC matching the Advanscene list, patching with Lunar IPS. Does anyone have any ideas as to what's going wrong? EDIT: If it helps any, NDSHeader lists it as having a busted header. EDIT2: OK, I found a selective IPS patcher which allowed me to disable whatever the hell the IPS was doing patching the header; with that gone all I had to do was turn off cheats and soft reset and it ran fine. If anybody Googling or something finds this, the tool I used is called IPSelect, and it's available on ROMHacking.net. I just raced on Waluigi Pinball and Tick-Tock Clock no troubles.
