it did run on my A500/060...
I'm giving you three dancing bananas, just for having a system like that.
:banana: :banana: :banana:
Actually I was thinking of games like Megaball, that have two different sets of graphics. The game auto-detects whether it's running on an AGA or ECS system, and then loads the appropriate set of graphics files so it will work correctly on either. Games like this are pretty rare, though. Someone told me over the weekend that Deluxe Galaga is the same way, although I haven't tried this yet.
Although I suppose "running but displaying wildly incorrect colors" could be considered running, as well, lol.
