To unlock all Danger Room courses enter the following code at the Danger Room course menu.
Can be entered at character selection or while game is paused.
Level Nightcrawler up to level 28. DO NOT add any skill points to Teleport Attack otherwise this will not work. If you already have points on Teleport Attack just talk to Forge and pay to redistribute Nightcrawler's skills. Assign Teleport Frenzy to whatever button you want. Now whenever you use Teleport Frenzy it should not use up any EP.
Go to the team management screen, then enter the cheat.
This cheat only works when visiting the store (run by Forge or Beast). When done correctly you will hear the sound of tech-bits jingling, as if you purchased something. This cheat can be done multiple times without re-exiting the store. However doing it multiple times can cause the game to slow a little, so if that happens just wait a moment and continue - you'll know when you can highlight between items again, doing the code before this will make you exit the store.
