Xenosaga I & II

Xenosaga I & II is a compilation/port of the first two Xenosaga episodes, with the ambition to close most of the plot holes. It uses the mechanics of Episode 1.

Debug Menu
A large debug menu is present, but can only be accessed with the following Action Replay code:

94000130 FFD70000 020F2E7C 00000000 D2000000 00000000

Hold Start + Select + Left until the debug menu appears. If you get a black screen or see some strange graphics on the screen, just press A.

Many of the menus are not working, or will take you to an inescapable submenu, requiring a reset to leave. You can access the minigames, see the museum, and do various other things...but there doesn't seem to be any proper way to exit that menu.

The third menu, "param edit", allows you to edit your characters, stats, and items. It is in Japanese, unlike the other menus which are in English. You can use it in-game, too: select a mini-game then exit it right away, and you'll return in-game. Press X to refresh the graphics, then you can save to keep your changes.
