I like it. I need this (~35 yo here). Beside, the design is really cool. I would love to know who sponsor visas but maybe that's not relevant to your most immediate customers. Good luck.
Had the ps1 a dedicated chipset for 3d graphics or was it a pre-written software renderer library kind of thing? Was writting a software renderer (with perspective correct texture mapping and a zbuffer, amongst other things) out of question?
