I added a lot of new stuff to Quake II PSP the last week: Inline models (like doors or ladders) and sky support.

The Quake II archive format (.pak) is now supportet. So you don't have to copy 1000 small files to your memorystick anymore. Just one big .pak file which is much faster transfered.
My current tasks are: clipping, lightmaps, a simple test mod, sound and music player.
The clipping on the psp is a mess. You can see clipping problems in some commercial games as well as in some homebrew stuff. You can read more about psp and clipping on pspdev.org: Thread 1 - Thread 2
My first idea was a brute force polygon subdivision algorihm. Each polygon is divided into 4 new smaller polygons. That's my current version and it is bad. It costs a huge amount of power for subdivision and a huge amount of sceGumDrawArray(GU_TRIANLGES, ..., 3, 0, verts); is called. That's why Quake slows down at the moment.
This implemmentation is not really good because you still have some errors.

This errors can be fixed with a dirty hack. It is just fake but it reduces black spots completly and it is fast. There are still some graphic errors but they are not so eye-catching anymore.

I'm working at a new clipping algorithm for the psp. Which solves the problem and not avoid it. I'll release more information for the developers if I found a good solution. Solve this problem is more important for me than light or sound in Quake because it is a generic psp problem.

In the next three days the first public beta of Quake II PSP will be released. My testers already played around with this beta version. Thanks to all of them for their work.
