I save the game right before entering the Store/Cafe with Micheal, and then upload to Save Editor. I change the values of ATK, DEF, MAT, MDF, AGI, LUK to 50, you have to change all of them, there is a lot and tedious to change. Be careful not to change anything else there. I chose 50 so its still interesting to fight and losing takes some effort. Anything more than 500 will break the game and some fights you wanna lose)
Param set #33 (Jason): Set ATK, DEF, MAT, MDF, AGI, LUK to 250
Param set #37 (Akin): Set ATK, DEF, MAT, MDF, AGI, LUK to 250
Gold to 35,000 (you don't need more than that)
Then you upload the ..\\www\data\Items.JSON
and change the
Kami Crystal #consumable #82
0) to 6 Kami Crystals
Download Save File to Computer, Right-Click the file, Properties and check UnBlock File Security. Copy to Original file and overwrite.
Exit game to Title and Reload your edited game file
Go to Item, Item, Kami Crystal and click on Manila to use it
Do that twice to skip to Level 3 (or more to really cheat the game). I save 2-3 for when you control Jason (on Map, not fighting) and you can give him Kami Crystal Upgrades as well.
If you are really advanced, you can add guns, power fists, Medic Kits, upgrade your Martial Arts by uploading the \\\www\data\System.JSON
Some values are not there until you do it or have it, in-game.
Starting from the beginning helps from breaking the game.
