This patch adds in the ability to charge up your missiles or super missiles.
Charge up a missile to fire a super missile instead.
Charge up a super missile to fire a super missile, which when colliding will summon in a tiny version of the plasma sba.

There are two versions of this patch; built-in and collectable.
Built-in makes it a basic feature, so once you collect charge beam you can use it.
Collectable adds two new item plms to the game (gfx included for those who wish) which need to be collected to respectively use charge missiles/supers.
Original idea by Benox, i made it into reality.
