Description

Currently, I need to see and watch the VRAM domain in a Neo Geo Pocket Color game. Bizhawk can show both RAM and ROM in Hex Editor, but it doesn't show VRAM, which would be very helpful.
https://github.com/TASEmulators/BizHawk/blob/5a105a156fb1db9d8d9aeb70029a60b7ccf2e3fa/waterbox/nyma/ngp.cpp#L47-L63

The only alternative right now is to use an outdated japanese debugger that is not very user friendly.

Useful information: Neo Geo Pocket RAM structure

Additionally: it would be also amazing if a sprite and map viewer could be added as well! But I figure that would be much more work.

Research direction

Start with waterbox/nyma/ngp.cpp at lines 47-63 and review the linked Neo Geo Pocket RAM structure. Trace how the existing RAM and ROM domains reach the Hex Editor, then determine what is needed for VRAM visibility and watching. Done means VRAM is available there; sprite and map viewers are separate, larger requests.
