I've started working on an asteroids conversion. I've converted the original vectors from the game to c headers. It's quite a nice piece of work as I can use the EVE GPU to create blending effects to produce a CRT like appearance.

The first job was to take the vectors from the Test screen in the rom. It works very nicely and using the brightness from the rom to feed into the additive blending I can retain the different levels of brightness and glow from the original. The different settings for the lines change the way the glow is rendered by the GPU. I'll try to write the game in 68K assembler and limit C code to the GPU functions. I'll see how that goes....
