*** THIS FILE IS ALSO NOW IN THE DEMO SECTION TO ENABLE THE "TRY IT NOW" FEATURE *** This may be of interest to absolute 6502 assembly beginners like me, although advanced 6502 programmers may cringe at the way I've done things here! This program does very little, but it is a repository of useful assembly routines for things like printing different bytes of memory (useful for debugging) as well as some basic math operations. I will keep adding to this as I progress through my assembly journey (I'm aiming to write my fractal BASIC programs in assembly). Thanks to the following YouTubers for their excellent tutorials on all things 6502: Ben Eater - YouTube Matt Heffernan - YouTube ChibiAkumas - YouTube (and also his excellent website: Assembly Tutorials: Learn 6502 Assembly Programming... With ChibiAkumas!) Function usage: (notation for cc65 assembler) jsr print .byte (list of PETSCII character codes to print, ending in a $0 byte) jsr println .byte (list of PETSCII character codes to print, ending in a $0 byte) jsr print_mem .word (start address of memory dump) Set MEMDUMPLEN to the number of addresses you wish print_mem to display. -
