Chonky Text in 6502 Assembly

Post by gavinhaslehurst »


A little demo of rendering giant text in assembly. It takes the data from the Lower/Upper character set in ROM and renders it in a large, "LCD-style" font. You can use .asciiz in CC65 for letters, or use a zero-terminated array of bytes to reference the character codes, as below (thanks to https://www.commanderx16.com/forum/index.php?/profile/5-jimmydansbo/ for the character set reference).

Found lots of bugs in the code. Now more stable. And more efficiently! And with typing! 




(For some reason, Try It Now hates this program, so recommend downloading and trying for yourself. Source code provided if you want to compile from scratch)
