Speeding Songs Up

This alternative method of speeding songs up consists in changing the BRSTM's sample rate. This will make the game play the song at a different speed, depending on the new value. It is recommended to follow the default method.

Prerequisites

 * A hex editor (HxD is recommended)
 * The BRSTM file you want to edit (and a way to play it)

Steps
Make a backup of the original file, in case anything goes wrong. Open the BRSTM file with HxD and press Ctrl-G on the keyboard. In the window that opens, make sure that From the beginning and hex are selected, then type 64 to go to the offset.



The two bytes at offset 0x64 are the BRSTM file's sample rate. Often used values are 7D00 (32000Hz) or AC44 (44100Hz).



Copy the two bytes and convert the value to decimal (a good website to do so is this one). Then add 6000 (or more) to the number and convert it back to hex.



Go back to HxD and paste the new bytes in the same place as before, then save the file. You can then play it with tools such as BrawlBox to see if it sounds good.
