So i haven't tried all the games. But some experience from my site:
ECS version: Not all games are enabled. Sound works great. A bit slow but playable. No music.
AGA version 030: Everything I tried worked. Sound works great. Still a tiny bit slow but very playable. No music ( but i have an 060 now)
AGA version 060: 100 % speed and music emulation.
All the games I tried were the classic ones. I did not try full throttle but probably that will only work good on a 060. Newer scumm games like broken sword are probably even slow on a 060. So I hope this helps a bit. So if you have a 030 you will be able to play most of them I think.
