Description

This allows you to look where the game writes a byte outside of V-Blank. Note that this would decrease peformance, so this should only work when Debugger (or Hex Editor) is open.
This also matches BGB's behavior (unfortunately, this is not a rerecording emulator, so rerecording has to be a separate request on BGB)

Research direction

Start by tracing the existing Debugger and Hex Editor/RAM Watch read paths for CRT-based consoles, using Game Boy as the example, and compare the timing with BGB behavior. Done should allow mid-frame reads of writes outside V-Blank, limit the performance cost to when Debugger or Hex Editor is open, and keep Hex Editor/RAM Watch synchronized with Debugger.
