Play Instrument test at Game Select menu; requires loading sample packs from each game.

I discovered an unused instrument test in Super Mario-All Stars, used for testing the samples. It exists in all other versions including Super Mario Collection, and Super Mario All-Stars + Super Mario World versions)

Despite the fact that Super Mario All-Stars is not included in this collection, the piano and other instruments are present and are also unused!

Because the game doesn't load all of the sound samples in a single sample pack into the SPC700 initially, all games need to be selected, then reset the game to reset the DSP registers.

There are invalid samples because they were either removed at different stages i development or moved to other addresses.

All games in the collection contain an instrument test with varying degrees of cut or changed sample pack definitions.

Here is what I found so far;

"I also discovered an oddity with the game select menu in all versions of Super Mario All Stars / + World / Collection, the game select curser counter goes up to FF / 255 then resets back to 0.
RAM address 7E0218 keeps track of this value. There are only 4 / 5 games.

Weird way of selecting a game.

I know how the game select menu system works though writing a disassembly is too much time and effort.

There actually are three banks for SMW sound effects. The menu music is oddly stored in bank 3 out of 4; $2142 ($000062)
Set game select sound effect bank; (60,61,63)
00A453??
00A427??

Set game select sound effect selection modifier
00A451??
00A425??
(01 - Default; coin)
(Game select music modifier
00A3B5??
(00 - No BGM)
(01 - Intro screen BGM)
(02 - Game Select)

;if BGM is set to 00 then SPC700 echo buffer is disabled.
