Two things changed to the 'Speed Booster' addon.
A) I added a little check to see if your Z is the same after a second.
B) Added 'Fusion' and 'Super Metroid' style Speed Boosters (SM requires to be running). Fusion sounds were hard to get, as there's no quiet place to get the sounds, while finding the Zero Mission charge sound was hard because the just mentioned reason. At least ZSNES supports disabling the channels music were playing on.
Tweaked up some sound loops, decreased the time required to check if the player's Z coordinate is the same as before (meaning if they are stuck going up and up at the skybox, it'll disable), and also added some "hooks" per variant of the Speed Booster.
Speed Booster in even more action. ('loud alert')
I should probably disable the Speed Booster when the player's dead.
Obliterating NPC's is next on my agenda. As soon as I remember how to make explosions again or successfully kill NPC's again due to the lack of an actual 'Kill()' function.
Disintegration is now included!
'ShouldCollide()' is horrendous.
