A500 OCS/ECS ... glitches on cube rotation part?! (Interesting, it doesnt happens on AGA!)
It is never interesting, most likely caused by some CPU emulation timing problem (possible even same as Anarchy's Madness 2)

Working with AGA config only means it is not badly coded

Feel Blue (Intro) by Oblivion

Another scrolling text issue (pic.2)!
Yeah, same problem.

A500 ECS ... on the end of demo, while I tried to do reset from WinUAE Propertis, it crashes!
It crashes very badly, stack pointer points to custom registers and CPU keeps generating exceptions = all kinds of garbage gets written to custom registers. (log shows it very clearly). Probably some programmed refresh rate register (ECS only) gets too bad values that are not fully validated.

btw, remember that only dump files from official betas can be used for debugging purposes.

A500 OCS/ECS ... upper row pixels of word "SARGON"?! (pics.1,2,3)
This is OCS only. ECS = single mismatched row. Emulation slightly tweaked to match this behavior.

Probably yet another demo that does not clear/initialize memory it uses and assumes some bootblock/menu etc.. does it. A500 confirmed, shows same garbage.
