Codes should all work, but I haven't thoroughly tested the current character exp and badge codes (but they should work, based on how the existing [but flawed] "all characters max exp" code actually works in practice). Back up your save before using any of them (since the game auto-saves excessively) just to be sure
For best results, turn off the codes when the effect will not be seen (IE: turn off "Fairy Skills Have Unlimited Uses" when not in a scenario/companion fairies are not unlocked yet. Badge and Exp codes should be fine to leave on since).
Special note: Do NOT use "All Attack Passive/Defense Badges" on Link before completing the first Legend mode scenario and finishing the forced Badge Market visit or else you will softlock when forced to buy a badge you already have. If it's too late and you need to fix that, use the following:
Code:
[Fix Badge Market Softlock (forced 1st visit)]
01100000 8B4EECCC 000000FD
Weapon badge codes are specifically not provided (except Link's Spinner/Horse badges, as they overlap with item badge values, thus might be accidentally reset) as many characters only have 1 weapon, but for the ones with 2+, the extra weapons' badges would be removed when setting the badges for the default weapon.
Edit: added/updated codes affecting Companion Fairies - as initially they did not function as intended
Edit2: Added weapon skill unlocks after I got the loop code working correctly ("Legendary" and the Master Sword's 2 skills will stay locked until extra conditions are met, so they will display 0 KOs to unlock until then). I'd add other weapon related codes, but those rely on conditionals using an address in a register and I'm unsure how to do those at this time
