OK, I will remember.

This kind of unnecessary rude talk is a common problem in forums. I know my hypotheses are clumsy, but I have absolutely no technical knowledge on the subject, so advices are more welcome than insults. What makes you think that I am stuck 18 years in the past ?
My aim is precisely to replace my real Amiga by an emulator, at least on my desk as I'm lacking space. To this end, a few years ago I tested several emulators on various PCs and various monitors including TVs, tried a few software hacks, without success as far as animation was concerned.
Now my main computer is a 2007 Apple Mac Mini, and I still haven't managed to obtain normal animation in UAE. I am willing to buy a PC again if this is the only solution, but since my finances are not in a good shape, I am still gathering feedback.
Anyway you are using a Mac, so if I am ignorant, then please explain me how these issues have been solved and how you manage to obtain normal animation on your Mac.
