I was going through my handheld collection the other day and found my DSi XL, which I haven't used in years. It is a launch system with the bundled Brain Age games, it also has the Zelda Four Swords freebie installled. I have the box and everything in pretty much new condition. more importantly it has the SudokuHax exploit installed and working, allowing Dsi mode homebrew. I've been thinking of selling it, but I wouldn't have a clue what it's worth, maybe no more than a regular DSi, in which case I'll probably just give it to my son. Anyone have any idea?
