notched it up to 486 33mhz and added a vblank wait and now its rocking a steady 70fps 💪

also, because it can't leave my brain:
this would be very easy to emulate in your head! you don't do anything. this code is an infinite loop, as long as you are not emulating VBLANK. (basically, "v = 0; while (v == 0) {}")
(...unless, maybe VBLANK is when she blinks? that would look *very* funny.)

Do I just need to set the Vblank Frequency to 120hz to run ACVD on 60 fps?

Electroniq WIP. New debugger feature coming soon. Jump from breakpoint to breakpoint or singlestep through your 6502 source code, all while drawing over the previous PAL field and showing the exact position of the 'electron beam' in the current PAL field (including hblank and vblank)

STEP 4: Modify ROM emulator to hold 2 identical copies in RAM. Alternate which ROM is active during VBLANK. Using 2nd core of RP2040, modify the bitmap table in the inactive copy with procedural data, then flip. Atari 2600 shows double-buffered 3D graphics. QED.

Bit of late night coding - refactored the video generation so that it is a state machine. It writes out 8 pixels worth of data every time the CPU ticks and generates a vblank signal. Plenty of scope for optimisation. Oh, and there's now a border.

ladies and gentlemen... we have cube
it doesn't animate yet because i don't have the vblank flag set up, but i have successfully written an RG-750 Unix driver and ported my homemade AFGIS library to GCC 2.95 on the 88K. yay

Was trying to get nmi and irq0 interrupts working (for vblank shadow oam copy) and dabbled with hblank some.
Stumbled across this nice twisty bar effect.
Camera footage since emus I can run don't support the interrupts 🥲. New loopy MiSTer core handles it reasonably well (little jitter aside)

I mapped out enough of the Atari System 1 BIOS to create a cartridge ROM that the motherboard will boot and that calls some fancy printing functions. The blinking, teletype, banner effects are from the BIOS but the fade in/fade out effect I had to do myself as a VBLANK task.

In the quest (hopefully not futile) to use a single vblank interrupt source across most #casioloopy emus (can't right now), I wrote a test ROM for it.
Not sure emu maintainers, who have their own things to do, will use it. I've done some emu work but am not good at it.

Shao saw this and corrected me on something.
The progression actually goes:
METHOD 1: [PID1] [PID2] [IV-1] [IV-2] {vBlank}
METHOD 4: [PID1] [PID2] [IV-1] {vBlank} [IV-2]
METHOD 2: [PID1] [PID2] {vBlank} [IV-1] [IV-2]
METHOD 3: [PID1] {vBlank} [PID2] [IV-1] [IV-2]
vBlank moves from right-to-left 😅
