Description

I don't like how the tile# are decimal. We should change them all to hex (keep in mind they are exceeding 256, we need 3 digits) but I don't have time now. Additional complication is possibly that BG tiles can be "negative" but I expect these are kind of "normalized" to tile numbers relative to the entire bank? It could be helpful to see BOTH tile numbers (raw and final-calculated). These should be displayed as e.g. $123

I'm looking at the gambatte core here.

For reference, compare to NES (the only one I checked) which is showing hex tiles in similar cases (albeit without a $ prefix which would make it more clear)

Research direction

Start by locating the Gambatte core's sprite and BG tile display, then compare it with the NES display mentioned in the issue. Determine how raw, calculated, and negative BG tile numbers should be represented; done means the relevant values use a three-digit hexadecimal format with a $ prefix, including both forms where needed.
