The best I could find is Dualis, its OAM viewer seems to work as you want, but unfortunately it doesn't run commercial ROMs. iDeaS appears to have some kind of OAM "viewer" in its debugger, although it just gives a bunch of hex and doesn't actually help unless you know what to do with it.
Unfortunately that's all I know, sorry!
