I decided to accept the challenge and tried to come up with a cheat table option instead of the save game editor option.
It wasn't too bad. I came up with a code that you turn on and then receive an item in the game via a treasure chest or any item you receive basically. It gives you 50 of every item when you get an item in game. Worked for me at start of game just by getting Lenna in party because you get Memento when she joins. I purposefully left off Valuable items as I believe having these may cause issues in the game. Enjoy and Merry Christmas!
Man, you seem to be kind of ungrateful even after all the special requests I did for you. Try showing some appreciation a little and not be so picky. There was an issue with my option after a reboot, so I worked on it and it's now working for me in this EDIT. All you have to do is turn the option on and get an item. It works fairly well in the start of the game if you want to restart. Try showing some thankfulness and perhaps give me some positive reputation for all that I've done for you.
It's Christmas, so I won't be online much anymore today.
Added option to not get the debug items and allow change of quantity.
