I've got the ScummVM 1.9.0 installed on my Milan040 but I never managed it to get it running. Perhaps the Milan040 is to slow for it?
PmDoom is just running fine on my Milan040 but I have to use it in the smallest resolution and the quality of the sound isn't very good. I think that also due to the 68040.
