I did the same thing, made a game in db classic and got db pro because it ran way faster, fixed some db classic bugs and had a better graphics. most of the code I had that worked before now is broke. I am still attempting to port it over to db pro, but so far its been a bunch of experiments that haven't had any positive results. collisions obviously work different in db pro and I haven't figured them out. my problem is mainly with polygon collision and .x models. you may want to try different patches, and see how that works. I have noticed that different patches do collisions differently. I'm working on other elements of the game so things are not at a stand still while I figure it all out. hopefully I can get it all working before the dead line for the retro remake competition.
