Amithlon seems to give me all my old software plus a super RTG Amiga and right now that's what I really want to use.
Long story short, that's why I'm looking at reviving Amithlon without the IP problems but I was curious as to what people liked/disliked about the original.
"Umilator" solved the main problems with Amithlon, had a proper HD installer... Bernd Meyer released some of the improvements as Amithlon updates for example generic drivers for network/audio that used Linux ones.
I think it definitely worths trying out, if you install AfA and latest stuff you'll end up with a nice system. You won't have latest OS4/MOS goodies but it's still a decent and fast way of running Amiga apps.
Amithlon RTG graphics worked (and still works probably) faster than WinUAE IIRC. input.device received the ps2 instructions directly or something like that. It felt very fast. I still keep my original copy but thanks to MorphOS I haven't touched it in ages :-)
