Vib ribbon rom usa9/15/2023 Sony gave a library and wouldn't allow people to hit the hardware directly, they eventually relented. I worked on a PS1 port, not an actual PS1, just when I had to ask why does the code do this, why is this like that, I usually got some hand-waving with "because it didn't have logical thing X but had Y, Kutaragi" But I did learn the "PS1 lean", to make the disc load. Also there can be no gaps or holes in the mesh, and they needed to be single, that might have been an engine limit rather than the hardware though. If you look at some meshes from PS1 games you will see where the artists had to make a bunch of "scaffolding" to move the polygons back around under and through things. So that is why a lot of PS1 games have the "jitters" So no FPU, zero floating point support, on a 3D system ( sure the DS does it too but that is a handheld ) Well the PS1 is probably not "batshit" unlike the other 2, just annoying. The PS2 and PS3 are legendary for their insane hardware, but I'd always been under the (possibly misinformed) impression that the PS1 was a fairly pleasant platform to work on, and that's one of the reasons why developers flocked to it instead of the comparatively nasty N64 or Saturn.
