When booting up the game, the default language is in Japanese and you'll need to change this in the main screen when you boot up the application where all the game options are available under settings.

If you want to use the boosters, be sure to manually change your controllers via the game app controller settings. You do not need to go into desktop mode. I wasted an hour trying to find a way to do so without a keyboard or playing it on the pc.

Booster Setup - Press the "steam button" and go into "controller settings". Hit "controller settings" again at the bottom middle and make sure enable backgrip is highlighted/turned on. Go to "edit layout" and under "trackpads" bind one of the Lclick or Rclick as the ESC key. "Keyboard" option for that should be at the top. Then go back to where you see quick settings and again make sure grip buttons are enabled on and highlighted. Below it you should see the grip buttons. Now bind L4, R4, L5, R5 as F1, F2, F3, and F4 for the boosters. Once bind, the grip buttons should now do the following:

Boosters (incase you are wondering) - F1 Speed toggle x2 x4 (Will not skip cutscenes but you will miss out on some voice dialogues and instructions in battles) F2 Overdrive mode (Always have OD and recover all hp/mp each turn) F3 Encounter toggle (normal, increase encounter, no encounter) F4 Auto battle (AI uses auto battle)

Furthermore, I played the HD version on my steamdeck for 2 hours wondering why the graphic is so trash only to realize the default has it on the lowest graphic settings lmao. It was just funny by that point and you have to manually turn everything up in the ESC settings.

Graphic Setup - Before doing this, make sure you saved recently as changing graphics in-game may cause crashes without a restart. Once you change the key binds as stated above, press the keybind for your ESC button and go into "system settings" and then "video" and change the graphics to the highest settings. Restart the application and everything should run smoothly and not on PS2 graphics now lol.

Item, Skills, and Gil Cheats - By pressing the ESC key, you can also go into "change parameters" and get all basic items, unlock all skills and max gil.

I hope this helps everyone play/replay this wonderful game on the steamdeck!
