I have been very interested in creating a first person adventure game for the virtual boy, but I am not sure of where to start. I’d like to create it in the style of DOOM for the SNES.
I always wanted to create a Raycaster for the VB but never got anywhere.
Other have created such engines, though. Maybe you could ask DanB to release the source to Ballface? M.K. also made one, but never released it: https://www.youtube.com/watch?v=bDAJYc0FVQo
If you don’t need to have fluid movement, how about a dungeon crawler like engine as used in Insmouse? I have made such an engine but it’s not in a releaseable state, yet.
