For any file with name ending in _LZ.dsir (DS Image Resource?), you can decompress the file by removing the first 8 bytes with some hex editor, and then decompressing it with DSDecmp (or your preferred program to decompress LZ-0x10-compressed files). Those files should contain the graphics. .dscr files (DS Colour Resource?) contain the corresponding palettes.
