There’s a Debug Mode in FF4 Ultima. If you want to know how to access it, please ask the team in the #spoilers channel in the FF4 Ultima Discord.

Here’s what you can do:

• gain any item to your inventory
  • you must know the item number that you want, of course
• reset event switches aka event flags in the save game you’re playing
  • why? To replay Events!
  • If you reset the right ones, you can regain party members that have left!
    • Regain Kid Rydia (Kydia)…
      • Clear flags 11 and 15
      • Enter Kaipo
      • Enter debug mode again, set flag 11 back after she joins
        • (or else you will have problems)
    • Regain Tellah…
      • Clear flags 11 and 30
      • Walk through the second screen of Mt. Ordeals
      • Enter debug mode again, set flag 11 back after he joins
        • (or else you will have problems)
    • Regain Cid…
      • Clear flag 9
      • Enter Baron Castle, walk towards Cecil's bedroom
        • Kill Baigan
      • Go to the throne room, kill Cagnazzo
        • The Stone Twins will be reinstalled in Baron! But they’re just clones now… You can still have Palom and Porom in your party
      • No need to set any flags after he joins
    • Regain FuSoYa…
      • Clear flag 71
      • Enter the Lunar Palace
      • No need to set any flags after he joins

Party roster Debug Mode Caveats

• Ensure you have an empty slot in your party before trying to regain a character
• They begin at their normal starting levels:
  • Kydia: 1
  • Tellah: 65
  • Cid: ??
  • FuSoYa: 85
• They bring their initial equipment
• Spell lists
  • Kydia = Rydia
  • Tellah and FuSoYa
    • have the same spells!
      • If you reobtain Tellah before getting FuSoYa for the first time, at an unknown point his spell lists will change to FuSoYa's
    • Their Black spell list will switch to Golbez's, post-Giant
• If you want to dismiss them from your party, you’ll need to run through the game event that does that! They are not dismissed by Namingway on the Lunar Whale!
  • Kydia: sail to Baron
  • Tellah: Damcyan bombing, or Tower of Zot
  • Cid: complete Babil first run (fireworks scene)
  • FuSoYa: complete the Giant

FFV Wounded Wardrobe Hack

Provides Job-specific sprites for the heroes when they’re Wounded (KO’d).

Not working as intended yet.

; Verison 0.5

; This only applies the Job palettes at this time; loading new custom sprites
; is Phase 2 of this project

; Two hook sites, both replace LDA #$E0 + 3×STA (11 bytes) with
; a JML to freespace (4 bytes) + 7 NOPs.
; Freespace translates the palette into a correct value for the Job outfit:
; (it's typically $E0).
