Oh, so now we've got two geniuses who can do the impossible and program a PS2 emulator that can run extremely fast on a low-end PC and do all of this under DOS no less!!!
Some comments here.
Although it's possible to write PS2 emulator for DOS and emulation of CPU and some other parts using optimized assembly can be faster than win32 because low system resources usage by OS. But...
1) We need to emulate complex GFX hardware, to do this in software
is extremely slow.
2) Only well-working 3D acceleration API is glide2x, so we can't even use all features of Voodoo2 - it will be only 12Mb fast voodoo1.
3)Even modern video cards can't do everything we need - for
example framebuffer reading - extremely slow because PC video hardware not designed for this and AGP is a bit one way bus.
5) Disk access - DMA under DOS only possible on some very old
Intel chipsets (430VX,TX etc)
6) Direct hardware usage or DOS OpenGL port... More difficult than emulator itself. And impossible w/o docs. Only well documented hardware
is 3Dfx cards ( docs, BIOS and drivers sources leaked)
So we can do not very fast emulator for V4-V5 only after a few years of insanely hard work.
So, it's definitely a hoax.
BTW I know computer capable to run PCSX2 with more than 200fps ( through PC emulator), even 150 emulator tasks at same time. Only one thing - $6900000, 450kW, 200 tons ... some sort of cheap PDA
Let's close this thread,eh ?
