I would like to write BatariBasic software, where TIA and sound registers would be used as numerical addresses instead of names. Mostly POKE-type of addressing, where loop index(es) are used as direct address(es) and values send to them.
I put this same question here (not sure if Batari Basic group is correct one).
OK, I have more specific example, from Atari 8-bit machines. There are a bunch of variations of short 32b demo, assembly loop here:
Reading system timers, bit manipulated, and putting to values to POKEY, VSYNC etc.
Anything similar to 2600 ? It doesn't need to be 32b, with proper headers etc, but similar principle, reading (semi)random timer(s), bit manipulation(s), and sending to VSYNC or similar. Glitchy graphics, which run long, any examples, would be used as visuals to chiptune gig.
I got my SIDE2 today, with SIDE driver v1.0, SpartaDOS X 4.46a. Apparently I don't have enough memory to run FDISK for partitioning (getting '158 Out of memory), all .XEX works, no .ATR as expected. I can't find info how to edit/alter/replace needed drivers etc on cart to get it work with Atari disks for saving works (I don't play, use it for music tracking etc).
Also, testing some intros that run well in several emulators, simple 32b intros, which read system timer, write $D000, and POKEY, this might be Programming area, not sure,
