When I try to start the game, it doesn't. I press 0, but game doesn't start. Other game version DOES start & play normally.

Hi, games like this really need to include the best version, and it's been a mistake on a few of your releases. C64 version is worlds apart on this particular game and features butter smooth scrolling vs flip screen on spectrum and cpc, and great in game music. I just can't bring myself to pay for it when the C64 version is the one I want. I made ONE exception with Bounder cause the other versions were good too, but I won't do that again. I am wondering why this is happening. My honest 2c....
