ok so I have everything completely setup for the emulator, most people reccomend the graphics setting to be in NULL PVR when i put it in that mode and start a game, it says Null DC_1.0.3_mmu.exe has stopped working. Thats it theres nothing else it tells me. If I put it on Chankast graphics it sucks the game plays but I can see anything or read anything, the dereamcast logo is on a black screen. I have all bios, downloads, good graphics card, direct x, C+++ pretty much everything and it still is like this, can anyone help me
