I will test more. I was able to get it running via Odamex on the XBOX, so in theory the Wii should have enough RAM to pull it off as well. I would imagine that the culprit lays in the old Chocolate DOOM source in this case as DOOM Legacy wasn't too friendly with it either. That said, on the XBOX it would crash or lock up the system occasionally and conflicted with Odamex's limited support for MAPINFO, but now all that seems to be resolved, so who knows, maybe by the time you are ready to do another release, they'll have it even more optimized and ready to play friendly with the Wii's limited resources.
