@gimulnautti I’m not aware of anything special going on after line 255. Certain VIC tricks require you to write specific registers at very specific cycles within a line, but otherwise the inner logic repeats in a deterministic way for every line, with certain functions getting disabled in the upper and lower border (even if you open them).

@cobbpg Thanks for replying.

I’m experiencing some problems with VIC retrieving character memory incorrectly if my raster interrupt lasts too long.

However, it does happen on the main program right after the interrupt terminates, and then rights itself at the next time it fires.

Puzzled. Even my demo gods couldn’t help me so far. Any help appreciated!
