Bizarre, okay.

Sounds like a lovely idea. Shame you need to go to the effort though.

Ouch. Think of the maintenance. Especially on disk images like ADF's 
where badly configured emulators generate more alternates because of 
high scores, save games, virus', etc.

True. Good. :)

I hate that emulator for exactly this reason. I understand that we are 
stuck with this now though.

If you are interested, I'll supply you with an IPF dataset too. Its 
currently XML, and I need to do some processing to add the usual 
metadata (year, etc) but I should be able to convert to whatever form is 
most convenient.
