Nothing tricky about it, just flip some bits at address $01. No sense keeping BASIC or the kernal around if you're not using it. LDA $01 AND #$F8 STA $01

- cgh 13y agoThank you for that. I never actually learned how to do this as my own games, written as a kid, were way too small.
- Luc 13y agoThese days it is so much easier to have access to all kinds of technical information on the C64. I remember travelling half a day to the single bookshop that sold assembler books. Learning anything beyond those books was mostly a matter of figuring out other people's code (e.g. the 'sprites in the border' hack).
