Chonky Text in 6502 Assembly

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).

It would be funny to see a chonky text adventure ?

I think it would be great for pinball, but I tried using a different color and it hanged:

It runs fine as long as you keep the default colors.

P.S. - this is inconsistent. It hangs at different times, or sometimes not at all. So, maybe not related to the color.

I noticed this Matt. I think there's a problem with my code somewhere. I'll take a look at some point. If you spot it, let me know! (You are an assembly legend)

Ps I suspect it'll work better if I write direct to vera instead of using CHROUT. And it'll be faster... just need to rewatch your tutorial ?

Do you have a GitHub? It would make it easier for folks to review, use, contribute, etc.

This did not occur to me! I'll look into this. It's been a long time since I've really done any proper coding. This lock down fascination got out of hand!
