Final Fantasy Hacktics

As the title asks. I've recently used FFTPatcher to give me control of Algus and Delita during Chapter 1 (cause I couldn't bear with their stupidity any longer (it doesn't take both of them to kill a single archer)). I plan on doing this to other guests in the future as I unlock them (I've never completely finished the game so, in order to avoid spoilers, I won't poke around in FFTPatcher too much until I know exactly which battles need editing). However, I've noticed that it's all too easy to let them sit KO'ed and not worry about reviving them like I would if it were a generic or Ramza. I wanted to remove Immortality from them but I don't know if that'll break the game (if for instance, Delita dies at Sand Rat's Sietch). Does anyone know how to set it up so that if any story important character's die, it triggers a Game Over?

Edit: Just realized this thread would be more appropriate in the "Help" section. I've reported it to the Moderators in order to get it moved.
Done.

So, I'm returning to FFT once again. I've never beat the game and had recently started back playing a re-balancing patch (LTF) but have decided that I'd rather start over and beat the game mostly vanilla using the new "The Lion War" patch. The only thing I want to modify is to make Gain JP UP innate for all classes. After doing some research, I'm gathering that is how I should go about it:

• Install "The Lion War" patch onto a clean iso.


• Searching through the ASM Request thread, I found a patch that says it should make Gain JP UP innate. However, I think it's not quite right. The patch is listed below:
  
  BATTLE.BIN
  Address: 1179a4
  Change to 00000000
  
  So, I went to look into the BATTLE.BIN documentation at the wiki and that address doesn't seem right. I'm guessing it should have been 17e9a4, which is the address of the instruction that branches if Unit doesn't have Gained  JP Up. I'm assuming the intent behind the patch was to "nop" the branch so that Gain JP Up would just always trigger. This seems to make sense to me but I wanted to check to make sure that I'm not missing something before applying the patch.
  
  But basically, I should be able to install that patch (or a corrected version) to the iso with "The Lion War" patched onto it by using FFTorgASM.
  


• Finally, use FFTPatcher to create a patch that removes "Gain JP-UP" from all Skill Sets and apply that patch to my iso.

Am I missing anything here or are there any changes to "The Lion War" that I would need to take into account when making these changes?

Edit: Or for step 3, could I just get away with unchecking "Learn with JP (Player)" under the Gain JP-UP ability entry?
