The problem with those games is that, they're very "tied" to original amiga hardware and therefore, won't run on Pegasos or A1, except on UAE.
Don't get me wrong, I still like those games, and they sure demonstrate well, what can be achieved with AmosPro...
Actually I was working on making DawnVideoPoker RTG compatible (keeping it Amos), and actually did make some progress with that... But due to some problems I haven't worked on it for a while... (Actually, I haven't used my amiga much anymore...)
