Fixed a small oversight that caused jumping Piranha Plants to always jump regardless of player proximity. Also added FastROM mirrors and removed a handful of redundant org commands for improved readability/Hijack Map alignment.
It simultaneously does and does not amaze me that this is a problem that even needs fixing. Either way, this patch does the trick, making proximity-based enemies behave a great deal more consistently (especially Rip Van Fish, what with the extra dimension of movement provided by water levels). If there’s ever another update to this patch in the future, it would be neat if all of the constant proximity values would be converted into defines - this patch would then be especially easy to use as an enemy proximity detection range changer.
