I found out my games were running slowly because under "options": "video", my screen was set to "window". As soon as I changed this, it started working properly. God knows why. ANYWAY, I have a question about cheat codes for C64 - all the websites tell you to type in a BASIC code of various types. However, it never really explains what a BASIC code is - maybe I'm really dumb, but can someone tell me what this means?
