EXPORT gbt_pause ; Pauses or unpauses the song.
; a = 0 to pause, anything else to unpause.
EXPORT gbt_loop ; Enables/disables looping at the end of the song.

EXPORT gbt_stop ; Stops the song.

EXPORT gbt_update ; Updates the player, must be called each VBL.
; Note: This will change the active ROM bank!
; - If the following value is uncomented, the total of banks allowed is 512
; (or more), but it's a bit slower. MBC5 ONLY, DOESN'T WORK WITH OTHERS!!!
; YOU MUST USE THE -512-banks OPTION WHEN CONVERTING A SONG WITH mod2gbt!!!
; - If it's commented, only 256 banks are allowed, it's a little bit faster
; and saves a few bytes. MBC1, MBC3 and MBC5 (and others).
