Yes! I own Sharp HC-4600 and I got an old version of HPC Doom from www.revolution.cx
But the screen was very wierd seemed like the colours were inverted or something like that, I think that It's because of the GameX lib I have it but i don't know where to put it and when i try to run the new version It says: Failed to load GameX
(no direct screen acces
)
Sorry for my bad english, I'm from Czech Republic
