| Howdy, I've reverse engineered some NVDI drivers for misc. graphics cards and improvised a SCREEN.SYS replacement. GIT repo is here:
EXTERNAL LINK
Still stuff to solve, bugs to fix. It's supposed to be used with OLs EmuTOS fork for the V4.

| There are rumours about it being fully reverse engineered, but I'm innocent to that. I just disassembled some drivers for the pixel formats I wanted, removed hw dependent code and rebuilt it. V4SCREEN.SYS is based solely on guesswork however.

| Excellent work! I wonder how much hassle it would be to get them working on the v2 cards?
