Hey. I'm the developer of PCem-mooch, which is a fork of PCem. I've been working on getting the RIVA TNT to work in PCem for a while now, and I've made good progress.

• VESA works pretty much perfectly, except in rare occasions and when using the 1280x1024 modes.
• NT4 loads the drivers and actually uses them, but hangs later on in initialization when attempting to initialize PFIFO.

I do need some help with NT4's issues tho. I am willing to give logs, docs, anything I can.
