I was supposed to report this last night but my sister had the computer, so here:
"Here's the emulator, it's still in preliminary form.
The games are perfectly playable expect for a few gfx errors.
For example, sprite zoom is still not emulated, neither are some sprite priorities.
And yes, the games are in English.
Here's the emu's site:

You only need the ROMs (the same old ones one the MAME set) and not the CDs."
(I suggest starting with Warzard/Red Earth. Awesome shit.)
