    Hi,

    I am sorry if this is a naive question, but how do I decompress or dissassemble a gamecube .dat file? I have a giftpia.dat that's 127 megabytes, can't seem to decompress it to peek inside. the Biohazard biofat app that can disassemble RE4's .dat files doesn't seem to work with it. Is there a tool to take them apart?

    hex editor reveals:
    Uª8-... ..l±..làÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌ...........€......d .‹Ò`...........æ......là...û......sà..Èo...&..<`..â€c...4..Ãà..ÑC...<."¢@..–û...J./9@..vc...R.3¯À.......`.;¼à

    So it might be U * like Mario Kart.

    Update:

    This currently comes up pretty high in google's search so for future posters:

    wszst works in linux be sure to use -M and then a big number if you get the file size error.

    ctools from chad is a geek or szs modifier worked just fine.

    .dat does not stand for an encryption method, and the giftpia.dat turned out to be a u8 file.

    is there a conversion chart of the gamecube japanese font to hex or at least what number corresponds to what kanji?

    the font used in giftpia is font_sjis.bin renders NTSC (J)

    update: is probably shift JIS

    Edit: It's not shift-jis the game just uses a hiragana and katakana sprite sheet.
