And how well does it do this? Surely not better than current PCs with WinUAE?
Of course not. WinUAE is the best version of UAE available (although I think they might have added JIT emulation to runinuae).
But the idea of using a PC to run Amiga apps seems to chap all the legacy hardware user's asses.
Frankly, I've got a copy of one of the more complete versions of AmigaForever and it just amazes me.
On the other hand, if its a primary concern (that you want to run legacy games) then AOS 4.1 systems from Acube aren't probably the best solution.
As PPC processors go, the Applied Micro CPUs used by Acube are fairly weak.
The processors used in Macs supported by MorphOS are quite a bit more capable. And the PA6T in the X1000 is also pretty powerful.
But, once again, they're all trumped by PCs.
Since my own focus is mainly on new apps for NG systems this doesn't matter.
I just keep a copy of AmigaForever around to run legacy games.
