Description
Summary
For unknown reasons, some background events appear to be ignored by the VDP Viewer, like this section of TiTAN Overdrive:
Tried the same thing in Genesis Plus GX Debugger in BizHawk 2.4.2 (due to #2786), and it correctly displays them.
Repro
- Load TiTAN Overdrive ROM
- Wait until you see the section in the image
- Open VDP Viewer
This is most likely because 3 of the colors in the palette are unused.
Host env.
BizHawk 2.4.2 Win10
BizHawk 2.6.2 Win10

Research direction
Start by locating the VDP Viewer and the Genesis Plus GX rendering or palette-handling paths, then reproduce the TiTAN Overdrive section described in the issue. Compare the viewer's handling of background events and unused palette colors with the debugger; the work is done when those background events appear correctly in VDP Viewer.
