I think the best way to create a nostalgic amiga with PC hardware is:
1:Install: windows xp and the drivers for your gfx card and sound ,last direct X and others drivers
2:then customize that hardisk that when you boot,loads windows without any adverts (black screen) and then automatically runs winuae in script mode and launch your preferred config
all of that is possible...it requires a bit of patience to design it
but there is still the floppy problem....(for nostalgic reason)........ insert a real amiga floppy disk and play is not yet possible on winuae ..
.so we must wait for news for a new floppy controller
