Nexis2600 or PSMonkey as he also likes to be called has posted some WIP news concerning his rather impressive Quake 3 BSP Viewer for the PSP:
Anyways small update for everybody. After a good day of rewriting my md2 loader in c (yes I know, shameful, should be cpp but i am waiting on a full rewrite), I now can finaly load, animate and render md2 models on the psp. There is still some work to be finished regardind child models (like the gun in the players hand) and etc but the larger chunks are done.
I plan to suport md3 & md4 in the future but i've given up on having it done anytime soon (so it might be in january/febuary).
