It seem to work decently for me. It took almost a minute to actually boot the game tho. I thought it had crashed, and the level also takes a long time to load, but when they are done, the game seem to run at an acceptable framerate, which some hiccups here and there. mostly when new stuff happens, like when you enter new areas or pick up stuff.
I also couldn't quite figure out how to mind the controls. I could get into the menu but when it told me to press the key that I wanted to use, it didn't really react to anything.
Still, way better than that crappy PS3 version that kept crashed non-stop and barely ran proberbly -__-;
Oh, and I'm on the O3DS btw.
Great work with the port so far. I look forward to see it getting new tweeks and improvements ^^
