I'm working on Xevious atm which is near completion. Next up is Donkey Kong, which has been 50% complete for about 10 years now. But these games are tate mode and I'm looking for a horizontal game to transcode next. Slim pickings for games that (a) interest me (b) are suitable for porting and (c) are horizontal. Can't say that I've ever been a huge fan of Wonder Boy though (played it a bit the other day after reading your comment), but in the absence of anything else I might be convinced to give it a go. My other thought is Pitfall II...
