Re: [Patch] 3dfx rendering accuracy

No no no! The dither subtraction only, ONLY applies to destination pixels of blended polygons in 3dfx Glide (usually) with the intent on reducing overdraw artifacts from a dithered texture map (creating another noticeable "big dither" artifact as a result). This won't do anything about anything els...

Re: Colored lines along the right/bottom edge of screen

I think that's the screen texture bleeding in with old texture data from a higher mode. Could probably use a color clear at mode change with a little memcpy (and probably would be useful for implementing backporch colors/margins)

Re: AWE32 Won't Show Up In 9x.

It's real behavior for non-PnP ("Plug 'n play") SB cards. If you didn't have the card in at Windows setup time, you'll have to add them manually through the Add New Hardware control panel applet (Automatically or not), and PCem doesn't emulate any later (>1994) variant of ISA Sound Blasters
