Probe Log

The Probe Log is a chronological text view of CPU and memory activity for a frame. It is available on platforms that implement startProbing.

Each line describes one clock tick:

(row, col)  <disassembled instruction>  <operations...>

The first pair is the scanline and cycle within the scanline.
The instruction column shows the disassembly of the code executing at that clock.
The remaining columns list what the instruction did — reads, writes, I/O and VRAM accesses, stack pushes and pops, and interrupts — with addresses and, where relevant, values.

Write operations are colored differently from reads so they stand out.

The view shows a complete frame, and might be incomplete during debugging.
