Some info on the original (pre-compression) data: It is the 565RGB encoding of
128x128 image. The original image is 32k and the compressed data is about
12.7k. The data appears to have an 18 byte header that I haven't been able to
identify so I'm assuming for now it's proprietary.

As the processor that normally does the decompression is pretty tiny (a 65c02),
I assume the compression algorithm is fairly simple such as RLE, LZW or DEFLATE.

Any suggestions would be greatly appreciated, otherwise the next step is the
6502 disassembler and 6502 op-codes make my eyes water.

Out of curiosity, you're not attempting to decode some images from a C64 game, are you? :)
