This is slightly off-topic, but I've found a couple of Delphi emulators out there. One of them is pretty old and was on Turbo in days of yonder: WinNES. The other one looks to be active: http://imperiopso.brinkster.net/sayarx/

Not really relevant to what you want, I guess, but interesting nonetheless!

If I were to get involved then I'd definitely take dibs on Gens (note my avatar, after all ). I didn't even realise that it was open-sourced! But that's all hypothetical once again.
