No, a Pixel64 can't show any Amiga games screens... you'll need a graphics card with a scandoubled pass-through like the Picasso IV or the CV64/3D to do that or a multisync monitor and a switch box.

Not true, read my post about fakenative again - but it's just a partial solution. I'd been overly happy if F1GP had worked - but it didn't.


Well, kinda, but very few games will work with it, maybe 1 or 2%, which would usually work with other graphics cards drivers anyway.

AFAIK the FakeNative mode are a planar emulation mode which converts from planar bitmap memory model as used by OCS/ECS/AGA to chunky mode as used by the graphics card. The game would still need to use the OS for its display, and almost anything that does that uses the OS calls to actually render too so would work on a graphics card anyway.

I think the only major use for the FakeNative mode is for Deluxe Paint or something (from memory) but I could be wrong there.

Any game that uses the blitter or copper or anything else like that won't work on the Pixel64 no matter what screenmode you're in because the card just doesn't have the right kind of blitter and the Amiga's one can't access the framebuffer and wouldn't know what to do with it if it could.

If you had an MMU I suppose you could trap the calls to the Blitter and reroute them to an emulation but it wouldn't be nice and probably wouldn't work right anyway!

Are you sure they were using the FakeNative modes and not the pass-through on your P-IV though?

Remember, the Pixel64 has no pass-through....

It is physically impossible to run 30-40% of disk games on a graphics card, because for starters there's no way for the game to talk to the card unless you load Workbench, which very very few (5% or so if that) games did.

The P-IV when running games just took the graphics display as output to the monitor and converted it to VGA scanrates, then displayed that. It's not actually displaying anything itself at all, it's just re-routing the display signal. The Pixel64 has no capability to do that.
