I happened to come across an old case of snes games. The one game that caught my attention was Super Castlevania IV. I vaguely remember playing it as a kid in the early 00's. However it looked completely different. It wa as if what I remembered and what I saw was two sides of the same coin in lack of a better term. Was there ever different versions of the game floating around back then? I have looked around the internet but not been able to come up with anything. The only difference being the PAL and famicom editions. I have a PAL cartridge. Anyone out there?

I don't ever really play snes game back in the days, so I can't be sure.

With the way I've heard of those lost media stories though, I'd say its worth cross-checking over with the archiving community.
