Door speedups Doubles the speed of the fadeout/in effect and door slide effect on going through a door. NOTE: There is a slightly noticable graphical flicker present on some doors when playing in Snes9x. This is an issue of a problem with the emulator, not this patch, as it happens with the original ROM in certain circumstances, too. Regardless, I've done what I can to make it as unnoticable as possible. CRE patch This makes the collectible items (Missiles, Super Missiles, Power Bombs, Energy Tanks) load their graphics to VRAM as-needed, as all other powerups in the game already do. It also allows you to place a large number of duplicate powerups in the same room, staying within the graphical limit of four different types of pickup per-room. This frees up some tilespace in the CRE (though it's not immediately present, as, I didn't force those graphics to blank-out in this patch).
