Custom debug menu for sounds

As requested, the patch and asm for the debug menu I made:


How to use it:
- apply to a clean ROM (NOT to your hack!)
- use quickmet anywhere
- jump button plays the sound, shoot button changes the track depending on the values
- use left/right to navigate, up/down to change values

The game will be paused all the time and not be playable as usual.

issues:

- track numbers have to be multiples of 3, else the APU will crash
- the values aren't labeled, so you may want to watch the video to know which value changes what
- some sounds are buggy and will never stop playing again, so you have to reset the rom
