    I can not open a file .bin, I want to translate a game that is in jap.
    There is also the file .ospr I do not know how to open? I know the file .spr representing sprites.

    FRANCAIS

    Je n'arrive pas a ouvrir un fichier .bin ,j'ai envie de traduire un jeu qui est en jap.
    Il y a aussi les fichier .ospr que je ne sais pas comment ouvrir?je connais les ficher .spr qui repr├ęsente les sprites.

    The game is Meitantei Conan Kakokara no Zensou Kyoku

    .bin is a generic file extension used by any number of formats right across computing. On the DS the only common versions though are the arm9.bin, arm7.bin and overlay????.bin and utility.bin files. The first three types are binaries for the console and usually can not be reduced any further and will need analysis at that level. Utility.bin is a common thing for the download play parts of games to be called.

    I have never seen ospr before.

    Anyway I took a look at the game.

    Whatever is not .bin is .dat (another common/generic extension), .ospr .g2pk and the solitary sdat file for sound.

    As it seems .bin could be used for a variety of formats within the game I might need to look at a bunch of different ones.

    I grabbed a selection of the .bin files for the game.
    Many appeared to start with FARC

    After that I saw what looked like file names and with common formats.extensions at the end of those (NCLR, NANR, NCER....) though others had ones I have not seen before like STEX. If it is like that from a few random samples I have to warn you that it could get pretty image editing heavy. I see there are also .bin files called script but more on them later.

    farc then
    There is a common archive format called NARC which sometimes also gets seen as ARC and CARC (compressed NARC) but here I am inclined to think the ARC is short for archive and F is just something else as it does not look like normal NARC to me. Custom archive formats are nothing new on the DS though.

    I will start with CHECK_BG_000.bin as I see it had a .BMP as the first file name (ho_bg_000_dt.bmp) and I am a stickler for developer leftovers if it is one.

    Sample of the file as it comes out of the ROM, the file ends at 83E0 hex


    As well a FARC all the files appear to have 020000000100 as the next bytes in the hex section.
    If I was doing better I would have picked another file with a more well known format at the start of it, that said looking at a few of them they might be compressed (type 11 which matches with the OSPR files) anyway so it does not really matter what I do.
    The file would appear to start at 02B8 which is interesting because at 14h is the data B802, this holds for other files as well.

    At 0100 hex there starts file names. There appears to be 19 of them, at the end of each name there appears to be between 6 and 8 00's.
    At offset 000A hex there is a number, this number appears to be a hex value for the amount of files it contains. This also holds for the other files.

    Slicing it off at the start of the file, forcing it through decompression and I do get my bmp image. Sadly it is just a bedroom background with things painted lime green, presumably for sprite work.

    The resulting BMP file is 019300 hex long which fits rather nicely with the 11009301 -- the 11 is for type 11 LZ compression (a common DS compression) and the 009301 when written as the DS would read it is 019300. This also fits nicely with the 00930100 I see at C hex in the header.

    Pondering it for a while and fiddling with some similar files (SEL_CHAR_KAZUHA seems to have uncompressed files in it which is nice) it seems there are three columns to the name thing. One appears to be the location of the names relative to the start of the naming section, one appears to be size and one might be location.

    Script files then.
    Looks slightly different to the other .bin files as it appears to start with scp (though they all seem to be compressed with type 11 LZ compression). Decompressing them I see what looks like it could be a normal file. I am seeing a lot of the 30 hex character which is not the same as either shiftJIS or euc-JP decoding schemes. If you can find a font in the other files (I have not found one but was not looking so hard) that would help.
    Other than at 8 hex there being a file length value, the next value possibly being length of something else and what is often a pointer section being longer for the bigger files (when I start seeing a lot of 30 I figure I am in the main text) I have not done anything yet.

    One decompressed file for others to see

    For a quick look I thought I would have a scan of the ospr stuff.
    The handful I tried underwent serious decompression when I fed them to a decompression program. Anyway opened in a tile viewer and some 256 wide 8bpp GBA format imagery popped out, the ones I picked had a lot of whitespace though so that explains the large size change for decompression.

    Either way it is followed usually by a STEX file which I guess I also saw earlier when looking at the .bin files. I am not sure they have palette onboard yet but between the ospr stuff and the STEX there is some more data which could well be dimensions (256=100hex but I will need to confirm that with smaller files, if there are any, or by trying it in the game. Attached is an image of the bmp I extracted as well as a couple of the ospr files I decoded. I used a grey palette as I have not yet extracted a palette. That is also text as images you see there so if you are going to do this project then be prepared for that.


    It has just gone midnight so I will have to leave it unfinished for the time being. Nothing looks especially outrageous here and it is not as simple as I have seen so enjoy some nice ROM hacking, we should all be so lucky as to find games like this to pull apart.

    The script files are compressed with LZ type 11 as Fast6191 explained. The text is encoded with Unicode encoding. It will have some control codes in-between text for furigana (the reading for Kanji characters.)

    The game used NFTR fonts (in data/common.bin) but it forced a big gap between English alphabets output. So you'll need to do ASM hacking to reduce that gap, or use dual-tile font. (I tried hacking it when the game came out some years ago, so this info is mostly from my memory.)
