I've seen a lot of people mention how wolfentein and doom and a lot of other 3d GBA games crap out on the dingoo. But I have found 3 FPS gba games that seem to run great on my A330's native operating system. Serious Sam, Medal of honor-underground, and backtrack. Dark Arena is a near miss, it acts like it's gunna work, but then stops mid game. Duke Nukem wont even work for like a second. Any one else find any 3d gba games that work? Thunderblade is alright too.
