Okay thats cool, not to worry I have seen a vid before on how to change the emulator in a config file or move the rom to a different folder, so I will try that.

It was mainly driving me crazy trying lots of things to do with video output to sort it and nothing helping.

Do you think it is just this game and the default emulator as opposed to all games? I have tried a few other NES ROMs and not noticed it, but with some games it’s not always as obvious as it was with castlevania because of the words missing letters.

Just wanted to say a big thankyou for your help and really quick responses so far, you’ve helped put my mind at rest that my setup is right (as much as it can be) and it just happens to be the first game I tried to play properly that had a slight issue. If it’s fine with nestopia you can close this one off as solved as I will just use that for this ROM :-)

Thanks again Matt
