PS fans probably know the trick where you can keep Nei alive after her inevitable death with NeiFirst in Climatrol. You basically have Shir steal some moondew from one of the stores and use it on Nei after she is killed. I guess the programmers supposed Shir wouldn't be of a high enough level yet to steal the Moondew and didn't think to program around this, is my guess.

Most say that you still lose her after the battle, even if you use this cheat.
There is also talk that there is a way to actually keep her alive permanently though. Anyone have any info on this?
