is there any possible way to make os 9 boot on a G5?
No you can't just boot into OS9. But check out this: http://www.inaddrany.com/mom/
Should provide pretty much what you need.
Sweet! I hadn't heard about MOM before. I was gonna reccomend MOL, but if MOM makes it outta alpha, and even beta, then it might even be better than the Classic env. for serveral apps.
Well, I've been watching the site for a few months and haven't really any progress, so don't get your hopes too high, but who knows, maybe the dev will get some inspiration if new interest is shown.
