Trying to compress a small file, it errors with "Could not decompress data", despite trying to compress the data. It works fine with other files I try, just this specific file doesn't work. It works fine with FW-KENSC, so I'm not sure why it doesn't work here.

Installing this compressor in my Sonic 2 disasm resulted in about a third of the Nemesis files not compressing identical to the original. I investigated a handful of the affected files, and the sole difference was that they were missing a single zero byte at the end. I would guess that Sega's original compressor inserted this extra byte if necessary to bring it to an even length.
