EDIT: I am actually talking about the WAIT signal on the Z80 CPU, NOT the HALT signal.
After the problem causing the graphics glitches and CPU crashes shown in VLog Update #1 was fixed (PicoRAM firmware update and ULTIMATE.INI file ADC levels adjusted), there is some more progress to share on the Z80 software side of things - check out this auto-magically rotating 3D cube! We can now record and playback rotation and zoom operations using a 256 byte record and playback buffer for "Cube Operations". One more update and we are done with this year's RetroChallenge 2025/10 - stay tuned for Update #3 next weekend!
