There's a lot of software out there that promises everything and delivers nothing. I felt more than a little dissapointed by some Sonic The Hedgehog demo on an Amiga emulation site. Looked like it was someone's first attempt on AMOS!
:-D
The good stuff usually uses a lot of Assembly language, C or even Blitz Basic.
With the Playstation 1 it only had a 33Mhz CPU, probably no more powerful than an '040 40Mhz. Really we should have had a 3D chip long before the Blizzard Vision PPC's Permedia 2.
One could always try mounting a tiny PSone motherboard into a 5.25" drive bay and genlock the output with the Amiga's. I wonder if you made your Workbench background a pure blue whether some sort of chromakey would allow you to have Tombraider running on Workbench without some expensive Picasso-IV TV-in combo...
