    ROM Hack Unpacking an archive in a DS rom - .iear

    I've seen the error before, but I've yet to diagnose why it happens. You can use this program to view the contents of a NANR/NCER/NCBR(or NCGR)/NCLR file set instead. :) (or Tinke, if it supports loading separate files)

    ROM Hack Unpacking an archive in a DS rom - .iear

    Alternatively, if you want to get the files in a hurry, just use this program to unpack .iear files. (you can use the command line, but just opening it as a Java program works as well) (I'm assuming that the format hasn't changed from when it was used in the Luminous Arc games though)

    I'd be stupid to not at least try and enter. Merry Tempmas to all =)

    ROM Hack Nintendo DS/GBA Compressors

    I am quite sure; my optimal method has at most [number of bytes left to compress] checks for each byte if you choose the optimal compression. ;] (the actual number depending on the possible length of the chunk starting at that byte)

    ROM Hack Nintendo DS/GBA Compressors

    I retract my statement; thanks for pointing out where I erred =) I only thought about an easy way to write the huffman tree at the time, but never took into account the limited size of the offset field. Do you happen to have sample data in which your tools outperform DSDecmp in terms of...

    ROM Hack Nintendo DS/GBA Compressors

    While I admit you beat me to an implementation of the LZE format (which I coincidentally started working on yesterday...), you weren't the first with an implementation for the 8-bit Huffman compression, and certainly not the only one. ;] (Your handling of the LZ40 flag byte is much more graceful...

    ROM Hack Ragnarok DS Sprite Ripping Request

    Since the heads appear to be customizable, I just picked one. Male: Female: To get these yourself: - unpack the rom, for example using dslazy - decompress the files in the subfolders of chr (the folder structure makes it quite obvious what's stored where), for example using DSDecmp - View...

    ROM Hack New version of 'DSDecmp'

    ROM Hack New version of 'DSDecmp'

    I as programmer interpreted that in two ways; - with a small tweak in the build, I can just as easily make a .dll which can be accessed by other tools to do the (de)compressing. - With this new version, I've expressly tried to set up the project/code to allow more formats to be included...

    ROM Hack New version of 'DSDecmp'

    I figured this would be the best place to post this; I've made a new release of my decompressor of NDS compression formats, DSDecmp. (visit the project page, including download link, here) With this new release the name has become somewhat misleading, since it can now also compress files back...

    ROM Hack Guitar Hero for DS (Extracting NoteCharts)

    Yes, but only for the implementation used for the DS (and Wii). It's also not LZ-specific, as Huffman- and Run-Length-Encoding -compressed files also have this header (with type {0x24 or 0x28} and 0x30 respectively) (again also only for the implementation used for the DS). * Not entirely...

    ROM Hack Guitar Hero for DS (Extracting NoteCharts)

    The compression scheme is quite simple, as it is just the built-in LZ-0x10 compression. The first 8 bytes are a custom header (5 bytes magic and 3 bytes file length), everything after that has the same format as any other LZ-0x10 compressed file on DS and GBA games. I've made a quick mod of my...

    ROM Hack Codec LZSS DS released

    I've fixed the bugs in my decompression routine (at least the ones that I could find). There's also a 'hack' for files that have a value out of range. It may be that this hack is actually the proper way to do it (the files I've checked that have that problem do seem to come out properly), but I...

    ROM Hack Codec LZSS DS released

    Your link is a 404, but I found a decompiler and did it myself. Since the format was so similar to 0x10 LZ, I've added support for it right away. =) EDIT: whoops, I was too eager. One or more small bugs are still present, which is/are currently being fixed.

    ROM Hack Codec LZSS DS released

    If anyone has a specification of the compression used in the ARM9 and overlay files, I'd gladly incorporate it. I know the compression used is the plain LZ (0x10?) but in reverse (read and write from end to start). However since only a part of the files are compressed I'll need to know the...

    ROM Hack Codec LZSS DS released

    If you just want to decompress, you can also use my tool, DSDecmp. All three LZ-formats are supported, as well as RLE and Huffman compression. It is command-line (or drag&drop) only, but the source is freely available.
