Creating a save point

Hi everyone. This is my first time doing any rom hacking for FF6. I'm trying to create a save file at different parts of the game that don't normally have them, and have been able to copy them over from other locations of the game using ZoneDoctor. However, sometimes adding the event for the save point either doesn't function, or it breaks the entire rom.

Here is the script from the save event:

Code:

CC9AEB: {C0-B5-81-B3-5E-00}   If ($1E80($1B5) [$1EB6, bit 5] is set), branch to $ CA5EB3 (simply returns)
CC9AF1: {C0-33-01-01-9B-02}   If ($1E80($133) [$1EA6, bit 3] is clear), branch to $ CC9B01
CC9AF7: {F4-D1}               Play sound effect 209
CC9AF9: {55-80}               Flash screen with color component(s) $8 (Blue), at intensity 0
CC9AFB: {D2-B5}               Set event bit $1E80($1B5) [$1E96, bit 5]
CC9AFD: {D2-BF}               Set event bit $1E80($1BF) [$1E97, bit 7]
CC9AFF: {3A}                  Enable player to move while event commands execute
CC9B00: {FE}                  Return

I'm assuming I just need to call an event that registered $1E96/$1E97 to bit 5 and 7? Does that enable the save function in the menu? Could I just set this once and permanently enable the save command until I walk over it again?
