- The reason that the AGA games you want don't run on graphics cards is that
- they don't use the OS in the first place. If they did, it would be a
- relatively easy matter to re-direct them to a graphics card, using
- CyberGraphX. They don't. They toss the OS right out the window and hit the
- hardware directly.
- I suppose with one of those insanely fast 300MHz PowerPC chips in a
- PowerAmiga, you could write an AGA hardware emulator that uses as CyberGraphX
- display. It's even theoretically possible to write an emulator to run *all*
- the games, but I'll say right now it'l never happen, because some games depend
- on the timing of the hardware so closely, that they break on many real Amigas.
- Look at all the problems that the new Amiga Technologies A1200 machines are
- having because games which hit the floppy hardware are breaking on the model
- of drive AT used. I wouldn't be too surprised if somebody wrote an emulator
- to run a lot of AGA software on a PowerAmiga, though.
- In the early years, quite a bit of Mac software hit the hardware. Apple
- had never sanctioned this behavior, the way Amiga, Inc. and Commodore did. So
- Apple didn't bend over backwards to make sure this software ran on new
- machines, and most of broke. This created confusion on the part of Mac users
- trying to buy software, but eventually it worked out well. Hardly any Mac
- software does hardware access anymore. The ShapeShifter docs note that
- Lemmings for the Mac hits the sound hardware, so the sound on that game
- doesn't work under the emulation. The rest of the software uses Amiga
- graphics, ports, and disks as if they belonged to a real Mac, because it
- doesn't hit the hardware.
- In short, as long as hardware banging goes on, RTG 'no matter what' is
- impossible, and hardly any Mac software hits the hardware.
