Please Note
Channel #5 is dedicated to the menu and should not be used for anything else.
All transitions use the formula Transition_time (in seconds) = param1 / 60.
The pan (audio L/R balance) value range is 0 to 127, where 0 is fully left, 64 is centre, and 127 is fully right.
The maximum volume is 127.
The tempo value range is 0 to 127. The normal tempo is 0.
Operations 0x10/14/18/19 do not work on the PSX game from field script [CURRENTLY CHECKING THIS].
Operations 0xC8/C9/CA are not implemented in the PSX version or PC version, despite field script calling them.
Operation 0xE4 does not work in the PC version, as it has not been implemented.
