won a lot with this cib, i never saw the silver one, so i got it out of curiosity. I have seen the arcade game one, and the standard ultra games style box...and that says hero turtles. totally befuddled as to what it's worth and can't find much on it anywhere :confused:

The Turtles is gonna be the European version.
Not sure the value, might want to check international ebay sales?
The castlevania looks like the Euro version as well

edit:
looks to be the pal version:
