Projectile Sounds

Various offsets to edit the sounds for beams, their combos + charge version as well as missile sounds when fired.

Beams & missiles use library 1 sounds; specifically, sounds 03-04, 0B-22 and C2.

Active Enemy Sounds

These aren't the same as “enemy hurt sounds” which can be edited right in SMILE. You only need to edit the middle value (A9 ## 00). Keep in mind what library the sounds are in. Values listed from top to bottom as I found them in the ROM, so some sounds are scattered around. The sounds are pretty isolated, so changing one shouldn't affect other things unless noted.

Values described as “?????” are ones I either couldn't hear any changes to after editing, or didn't check since the library sound used was mute or used to clear other sustaining sounds. The latter mostly applies to “B9 00 00” instructions. I didn't feel like breakpointing each one.
