These are some of the dangers of using the action replay. me, my sister, or my cousin have experienced all of these.note: the results of doing the following things may result in but are not limmited to crashes, data loss, pokemon or item loss, corrupted data, or even a brokem DS.
When you use the have all tms/hms cheat you will get 99 explorer kits in your mail pocket. don't use them. using them may lead to crashes when entering the undergnound, the battle tower, or amity square. Also don't use that cheat that often, that will result in random crashes. If you see a bad egg in battle, don't attack it. that may also end in a crash. never go in the mystery zone too long. that is how the game is broken. don't go into the union room or the colliseum with the action replay in or the game will crash. and one more thing, if there is ever something that should never happen under any surcimstances, don't save.
