Shining Force EXA - Cheats

Hint: The Real End
To access the hidden dungeon and a last boss otherwise inaccessible during your first playthrough, you must beat the standard game once through. This will grant you access to the start of the fourteenth chapter in the state you were in, items and all, when you beat the game. You can then access the hidden dungeon and the real final boss.

Hint: Infinite Energy
After you beat the game, a new location will be unlocked on your map. Head to this location, and enter. In the first room, head straight to the stairs. The stairs are littered with cannons and monster generators. When destroyed, they will give 15,000-19,000 energy per kill. Go up the stairs into the next area, and then back down. This will make the enemies respawn. You can repeat this process for as much energy as you’d like.

Hint: Avalon’s Body Parts
There’s a secret character in the game named Avalon. Avalon has eight distinct parts that must be collected in the game and assembled in order for the character to be unlocked. The list below has all eight parts, and their general location.
