Misc chipset options "problem"

20 November 2005, 20:52

I found two demos which do work with WinUAE 1.0 perfectly without the "cycle exact CPU and Blitter" option. With WinUAE 1.1.1 they have at some parts graphic "corruptions".

Passion - Chronic
Abyss - Vertigo

Can anyone confirm this bug? Or maybe the "cycle exact CPU and Blitter" option is not anymore so compatible? As mentioned above the demos work with this option turned on but the speed goes down very much on my machine.

Does nobody have the same problem?

There is "nothing" wrong. Non-A500 modes are not very timing-compatible (and probably won't be too soon either and never if JIT is enabled)

Basically above demos only worked accidentally.

Search older posts for more info (68020+ caches, chip ram timing)

Yes, and as this is no demo problem, it should be moved to WinUAE problems (imho).
