I unpacked a ROM and the /data/chr directory (where I presume all the character animations are) is filled with .dat files. I've searched several guides (including a few on this site), and I've seen other formats (such as .bin and .aar) mentioned but nothing about .dat. I tried the various tile viewers anyway but all I get is a jumbled mess no matter what program settings I use. Is there a certain method used to extract from .dat files, or do the formats have to be reverse-engineered on a game-by-game basis? Alternatively, there's a program called CrystalTile2 that seems to be popular but the topic here about the latest version links to a site that seems to be dead. The mirror posted in that topic is also dead. Could anyone provide a download to the latest version of CrystalTile2? The game in question, if it matters, is Nine Hours, Nine Persons, Nine Doors.
