Lightmapping on Dreamcast

It’s not much, but it is working. Annoyingly, it does require using transparency for the lightmap polygons, which is a pain as it reduces the render time significantly. I’ll look into ways around it. Now I’m interested in getting static props and animated characters added to the scene to see what happens to the performance. Also, the lightmap is ARGB4, so it’s not the best quality. I’m thinking of using either 565 or YUV422 textures.
