Starrfoxx go for it! Ten years ago I programmed some stuff in sas/c and amos. But I never learnt enough to write a good game. But If i will some spare time i will surely write something. I think for PPC. If I find a good software for it.
There is not much Powerup/warpup software but I will create some. Someone surely will say: why not for pc why for this ancient machine. Just because i love it.
