This features a very strange compression algorithm. I'm not familiar with the theory behind it at all ... I wonder if anybody knows the name of it? I suspect it's using a table-based huffman code.

Updated: extcd now guesses file extension for generic file types.
Updated: spdc2bmp now supports type 1 compression.
Updated: Fixed an alignment bug in spdc2bmp for some images.
Updated: Now supports アトリの空と真鍮の月.
Updated: Now supports ななプリ.
Updated: Now supports ふぇいばりっと Sweet!.
