Quad Challenge

Test Menu
Enable patch code (Gens/GS) and reset. C makes a selection, B returns to the title screen. Both the JP and US ROMs have the same date (91.06.17). Both versions have identical menu screens (the screenshot on the left is from MegaTrax).
 * 1) OBJ Test: sprite viewer. Use the D-Pad to select, press B to exit to the Test Menu.
 * 2) CHR Test: shows the contents of ROM, some chunk at a time, as tiles. Use the D-Pad to select, press B to exit the Test Menu.
 * 3) Sound Test: use the D-Pad to select a sound code, C to play, A to stop, and B to exit to the Test Menu.
 * 4) Heat Select: apparently selects a track to play? not sure... D-Pad selects, C races, and B exits to the Test Menu,
 * 5) Player Test: another sprite test, but with player sprites. Left and Right select a sprite, Up and Down scales the sprites, and B (you guessed it) returns to the Test Menu.
 * 6) Ending Test 1P: shows one of four endings for 1P mode. The text appears to be hardcoded for the Easy mode regardless of which you choose; only the colors change. B on the select menu returns to the title screen, and there seems to be no way to quit the ending itself.
 * 7) Ending Test 2P: shows one of six endings for 2P mode. B on the select menu returns to the title screen, and Start during an ending resets the game.
 * 8) Game Over Test: shows the Game Over sequence, then goes back to the title screen.

Code to jump into the Test Menu begins at in the Japanese ROM, but it appears to never get called, nor is there anything in the code hinting at a possible use? (TODO).
