Hiya!
This jam seems right up my alley, while I'm not a game developer I have been looking to write something for an old-school console for some time and this fits the bill quite well.
I noticed on the vircon32 specs page that not everything is fully documented. While I don't have necessarily high ambitions for the game I'm trying to write, I suspect there are things I'll find along the way that I might like some official response on.
