The download point for some emulators which don't seem to be widely available, either through the failure of the original website, (Atoric and QLem), or extreme rarity in the case of (Nesulator).
AtOric - Oric Emulator (v0.9)
QLem - Sinclair QL Emulator.
NESulator - Ed Cleveland's NES Emulator for the STe and Falcon!
There may well be more to come, when I can be motivated to update this section. Also there may well be some little additional (legal!) goodies to come to this page as well.
