@harrison:
Lotus 2 and 3 never worked for me on my unexpanded A1200, but when I bought an 8meg trapdoor board they worked fine...I guess they just needed some fastram.
I have gotten all but one or two games to work on my 1200, the one I have a problem with is Mega lo Mania, it seems to crash after a bit, and I can't get Moonstone to work no matter what!
With an A1200 and fastram, I've gotten pretty much all of the old games to work, a few of them just need some extreme coaxing and combination of degraders. Sometimes hours of ridiculous trial and error just for a stupid old game I don't even play afterwards!
For some reason I have had no problems at all with the Escom disk drive. Even the few really old games I have work fine.
