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.

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

metadata (year, etc) but I should be able to convert to whatever form is
most convenient.
