Thanks, I was a bit worried that the group was dying. :D
Anyways, my suggestion is Elder Scrolls: Daggerfall. Abandonia Link
Mega-Drive: Gens
The best mega drive/genesis emulator in the business in my opinion. Plays games in zip files, use the last of the video filters for the best looking screen.
PS1: ePSXe
I've found this to be quite good after I figured how to set it up. The Bios file needs to be downloaded separately as far as I remember, there are youtube vids showing how this is done. It works perfectly with my arcade stick and my wired xbox pad too which is a plus.
