Desperately Need faster text output #4

Closed tschak909 closed 5 years ago

tschak909 commented 6 years ago

We need much faster text output, that takes the 6x5 font data in the character set, and transfers it to the display, but with transfer modes:

Rewrite, black background, white foreground
Inverse, white background, black foreground
Erase, transparent background, black background
Write, transparent background, white background

I can of course figure this all out on my own, and spend months doing so...would really like some help.

I wouldn't mind helping out on this project. I've actually got a couple working C64's myself. May need a bit of help with the toolchain, however. I'm guessing this is all in gcc outputting 6502, but where does the c64.h header come from?

tschak909 commented 6 years ago

This is done entirely in CC65, a cross compiling toolchain that outputs native 6502 code. It supports a huge chunk of modern C.

Awesome! I'm finishing up a C64 joystick microcontroller project at the moment but I'll try and get a dev environment working on my machine and start playing around with this. Sounds fascinating!

Thanks to Flashjazzcat (Jon Halliday), Atari now has this. Now need for Commodore and Apple. Will bifurcate for seperate targets and close this issue.
