So I said in some other topics about my isolation problem, and how I'd get the brunt on the Inn Guests outfits because I surely won't find 30 different DS players here in my city with Dragon Quest IX, so I'd have to resort to the AR codes, right? I guess a fraction of the people here would do the same.
Thing is, I gone there, and I've regretted it! Was using the code found on GBATemp's for max inn level, as follows:
Aside the intended effect... It corrupts the Guestboard option. When accessed, the game froze, and the save got erased due to malfunction! I backed up the save (yeah, the *ahem* "something else"), tried the code in many fashions, only to have the same result, not only on the Guestboard option. Alltrades Abbey would freeze at chance, so would entering some cities (Stornway remarkably) and dungeons.
In short, the code above is dangerous. Do not use it! --- Phantasy Star Zero: 2107-1196-0557 > Exor-2, Exor-Uno Blue Dragon AS: 5199-6074-1427 > Billy
You've flipped the "there have been 30 guests" flag without the game ever having those 30 guests. I'm guessing it has garbage in there to make it count, but this would cause some rather fatal glitches.
I believe the solution if you're using that code is "don't ever view the guest book. Period." --- *Casts Doom on everything* You all must now feel the pain that I have felt...DIE!
You can actually fix this with a second like two-line code that deletes all the fake/invisible guests from the guestbook when activated, leaving you with a maxed-out inn and an empty guestbook and as of 20 hours later a totally fine save file. In fact, my only technical problem so far was before I ever used that code; the first time I went to the Bowhole the game froze when I talked to the quest NPC right inside the door.
