Acid Missile Unofficial 2.2 Port 2.2.4

Been a minute huh? I finally updated it to reflet the 2.2.15 update.

• Ultimate Rings has been added to the Special Stages so that they don't disappear.
• Storm Ruins Zone 1 music has been changed to MP_GL2 in relation to MP_GLZ being different now.

There was a typo in the amount required for the golden ring emblem in GMZ 2.
Went from 383 to 303 rings.

Special Stage 2 - fixed sound effect
Special Stage 3 - fixed conveyor belts not working and sound effect
Special Stage 4 - fixed the outside ceilings not being F_SKY1

Fixed an overlapping monitor near the end of GMZ 1, there's now only a eggman monitor.
Which means now the Golden Ring Emblem has been nerfed from 343 to 333 rings.
