Nintendo DS/GBA - Some of my compression tools (source code included).

Maybe the best set of compression tools for DS/GBA.

Support both encode and decode data:

• BIOS compatible compressions (DS and GBA)
  • RLE
  • LZSS (with my own optimized version, ‘LZ-CUE’)
  • Huffman (this first and only tool to encode properly the 8-bit mode)
• non BIOS compatible compressions (only DS)
  • BLZ (used in ARM overlay files, RPG Maker DS)
  • LZX (also known as LZ11 and LZ40, used in some games)
  • LZE (used in Luminous Arc 2, Luminous Arc 3)

Sorry, the ‘readme’ file is in spanish language (I’m too lazy to translate).

Run each command-line tool without parameters to view their usage.

• version 1.1:
  • added ‘history.txt’ file
  • BLZ: added support to encode ARM9 files with 0×4000 bytes of secure area

• version 1.2:
  • BLZ decode
    • updated messages
    • do not remove the latest 4 zeroes in uncompressed files
  • BLZ encode ARM9 files
    • check the size: greater as 16KB
    • check the ID (0×0000): FF-DE-FF-E7-FF-DE-FF-E7-FF-DE-FF-E7-FF-DE
    • check the Secure Area 2KB CRC16 (0×000E): CRC from 0×0010 to 0×07FF
    • check the Secure Area 2KB end (0×07FE) : 00-00
• version 1.3:
  • solved a bug from the update 1.2 in Huffman encode
• version 1.4:
  • solved a bug Huffman compression (1-2-4 bits)
