C#: A step into a new system, where game-specific formats can be defined as plugins, preventing users from having to download DSDecmp itself again and again. Such plugins must be stores in a 'Plugins' folder in the same location as the DSDecmp.exe.
...
To keep the base program mobile, all native NDS formats do not require plugins.
The 8-bit Huffman format cannot be used to compress at the moment; thanks to CUE a bug has been found where the offset-field of a node overflows, corrupting the compressed file.

C# (previous one as well): re-implemented the LZ-0x11 algorithm in the new structure. Also updated the GBATEK-like format description of the format, hopefully correct this time.

Augh. idiot-bug fixed. (the last 0xC bytes of arm9.bin should be ignored, no the first ones)

Last adjustment to the LZ-Overlay decompression for now, until I can compare a properly decompressed file with one that doesn't come out right with this program.

Minor adjustment in LZ-Overlay decompressing, catching more Disp-values that are too large.

Added support for compression used in overlay files of the DS, as well as the arm9.bin file. The format is mostly LZ-0x10 in reverse, but has a small difference in the calculation of the Disp value for compressed blocks. The complete file also need not be compressed.

Added a new compression format in the C# source: type 0x40 LZ77/LZSS. It differs not very much from type 0x11 in compression size, but has an odd way of storing which blocks are compressed.
...
A Java-version of the scheme may come at a later time.
I _think_ this is a built-in compression, but it could also be a format Camelot made and used only for the latest Golden Sun installment.
Oh, I've also added the MIT licence to the C# source code file.

Upgraded sln to VS2008.
...
Also updated the source to match my local copy. No changes in decompression, only usability,

added source code for both C# and Java.
...
Note that the Java algorithms are a port of the C# ones, and only the LZ10 and LZ11 have been tested of the Java implementation.
