While browsing through the data for Harvest Moon Sunshine Islands, I came across a dozen of xbb format files. I was wondering if anyone knows how to unpack these, as they contain the graphic files of the game that I want to modify. I've done a google on xbb file formats for nds, but it yielded no results. The only relevant thing I could find was a really old post here by someone named Gryphon, whom claimed that he made a tool for unpacking these and that these were simpler than narc files. However, he never did upload his tool and I am not quite sure if he is still around (Sent him a PM about it, but realized that his post was dated way back in 2009 or so). So my question is, does anyone here know how to unpack xbb files? I can't even find any documentations on them, so I am hoping someone who is more well verse with NDS hacking than I am can help me out. I'd really appreciate .
