Sorry but for running 68k games and following Os4 development WinUAE PPC on a fast PC is a way better/cheaper. Maybe after releasing 3d drivers X1000 would be useful but now WinUAE provides similar support except speed.
You can't truly follow OS 4 development on WinUAE. For starters, WinUAE still has some bugs in it, and is likely to cause instability.
Secondly, WinUAE supports 128MB RAM max, which is very limited when you want to run things like Odyssey, let alone Timberwolf.
Then there's the composite support which is completely missing under WinUAE.
Then the fact that WinUAE's FPU emulation is incredibly slow.
WinUAE's emulation of a CS-PPC is
not a good indication of OS4 and should only be seen as a small taste of what can be achieved.
