Re:A Great Old Timey Game Programming Hack (2013) by dzdt on Saturday October 13, 2018 @10:24AM (#18208075)
The commodore 128 allowed the same trick of moving the machine stack and zero page. But the 6510 processor didn't have useful multiple-push or multiple-pull instructions so the possible speedup wasn't as much. Also in practice people writing games for the commodore targetted the C64 as it was a much larger market and the 128 was backwards conpatible so nobody bothered witb 128-only tricks like that.
