I'm actually quite used to game programming but the trouble with gemrb is all the obscure data formats and needing to know how the infinity engine does all its things. It's quite a task to even familiarise yourself with the codebase. I also have no idea about things like openal etc.
I come more from the gamecode side of things than the engine side.
Plus I have another game to work on. I can report bugs and do android builds etc and maybe hack a little here and there but can't join full-time unfortunately.
