I know Dizzy from anywhere. Even if I didn't play it on commodore. I spent 6ish hours one day trying to beat it without save state on an emulator(I had the original gold nintendo cartridge too) and could only make it to the last boss. Decided to use it save state to finally see the ending. Wow was it short but I felt satisfied! XD And that is Karate Champ at the bottom, yes?
