Missile station enhancer
This will make Super Metroid's missile stations a good deal more useful. By default it makes them refill Supers and PBs as well as missiles, and you can uncomment a couple lines to make them also restore energy and/or reserve tanks. It also changes the message that pops up so that it still makes sense. The station will activate whether or not you need anything refilled. You should be able to use this on existing hacks too, as long as they haven't changed the RAM addresses of your supplies or the code for missile stations. I'm releasing it as an .asm file since that's simpler than making a bunch of different versions.
