Bargain is a highly efficient image compression format for MSX computers.
This page contains the conversion utility, an English manual, many sample files and Z80 assembly sources for compression and decompression.
The documentation about the file format is contained in the BN142.ASM file. It's in Japanese, so you'll need to use a translation service from Google, Bing or Excite.
Its website seems to be gone, but thankfully there's a backup on the Internet Archive.

I'm attaching here the files I could salvage, just as a precaution.
Thanks to PAC on MSX.org, we have the missing sample files.
