Need Info and Price Check,Revenge of Shinobi Rare Version SG

[mgriff]

I've heard there is a rare version with batman and godzilla, that was changed shortly after release. Are all the ones in the orignal release packaging have these bosses. And is the Sega Classics one, the revised version. If the original could have either the original or revised version, does anyone know what date/month/year this was changed. I still have the orignal reciept from mine. I've never played far enough through the game to know and I don't have a game genie to get to the level either. Also, what is the value of the rare version. If anyone could give me info on this, I would appreciate it.

thanks,
