Summary	04644: Tilemap viewer always broken / displays in shades of Blue
Description	Tilemap viewing is always broken, even on games where it should work fine. Gumbo is an easy example, the tilemaps in the viewer now show in various shades of blue. (This isn't a driver with custom handling of the tilemaps, but instead the most basic use case, so it should work, and did work prior to the recent updates)
