Activating this trainer:

Press F1 at main menu.

Listen for 'Trainer Activated'.

Press desired hotkey. All hotkeys can be changed on the trainer.

Trainer Options:

Numpad 1: Unlimited Health

Numpad 2: Instant Synchro Gauge

Numpad 3: Easy Second Drive

Numpad 4: Endless XP

Notes:

Numpad 1: Unlimited Health - toggle on and your health is prevented from reaching zero.

Numpad 2: Instant Synchro Gauge - toggle on and each attack that would provide synchro power to the meter will instantly fill it and give you a Synchro battery.

Numpad 3: Easy Second Drive - toggle on and you can enter Second Drive even if you don't have any Synchro cells/batteries.

Numpad 4: Endless XP - at the end of the mission when you can spend your XP on your characters, toggle this on and then spend XP as much as you like. You will need to eventually turn it off and then basically CONFIRM, but once you toggle off DO NOT SPEND ANY MORE XP, even if you have more. Also, DO NOT USE the ALLOCATE ALL option, or the way the programmers lazily programmed the game, the game will endlessly loop trying to give you the XP.
