Mode 7 Bit Depth in Tile Viewer Issue

[Yoshifanatic1]

In the Tile Viewer, if you set the Bit Depth to "Mode 7" or "Mode 7 EXTBG", the Source is forced to be "VRAM" and the Address to $0000. While I know that mode 7 data is hardcoded to be at VRAM address $0000 on the SNES, there is no reason why the tile viewer needs to enforce this. That prevents the user from being able to see uncompressed mode 7 graphics that are stored in the work RAM or ROM.
