BGM Test Mode
There were separate BGM test mode at the development stage. Bank 0x0D still contains it at CPU address space offset 0xB800. It should be fully fuctional, but all offsets to the library functions are not the same as for final release. Previously all system routines were mapped to 0xE000 area, but now they are mapped to the 0xC000 base. It is possible to relocate all offsets to the correct values and get working test, but there is too much editions needed. You can just see how this screen should look like with the current test mode palette.
Note, 0x1F BGM index is marked as "SAMPLE", it still there and can be played in current test menu by the same index and never using in game.
