The fact is that, we don't know how legacy Amiga emulation is implemented, as RCK says. Are you sure the custom chips are as wel lemulated in Amithlon as in WinUAE/Fellow? Because that emu is using Picasoo-like emulation shiznit, and that does not need aga/ecs/whatever chipset emulation
WinUAE runs mighty fast on my P133 when I have Picasso support on, but it slows down to a crawl when it has to use the 68000 emulation. And if I switch to a non-picasso app, then I'm in snore-o-rama again.
I'd wait to see how this thing runs games. I bet the legacy chipset emulation is pish.
