Can DS/DSi DLC even be played/installed on the systems without the sudohax??
Well, we need the save data before it's too late to grab it.
And about Dragon Quest IX, there are no codes for the JP version (which has more content) or the respective French, German, Italian, Spanish versions, and we're aiming to get a comprehensive list of as much as possible. But at least there's a save editor. If anyone can post saves as well, that would be lovely.
And as I explained in the first post, the "DLC" is actually contained in the DS cart, and using a save where it's unlocked on any system unlocks it.
For the DSi games, we don't have many exploits yet, but when we'll have them it will be too late to grab the saves. I'm at least sure the saves can be grabbed at least.
