BZ2 2010Get It   (details) 49/50 48 ENG   35 KB / 1 KB
This is the successor to BZ from Mika Heiskanen, compressing more and faster than its predecessor, while achieving 100% compatibility. BZ2 typically compresses 40-100% faster than BZ and decompresses ~50% faster, while at the same time seeing the same or better compression. It also uses less memory. Multiple versions are included, including one optimized for speed while achieving the same compression ratio as BZ, and another optimized for compression, while still performing better than BZ.

LZD 0.4c   (details) 49/50 48 ENG   21 KB / 1 KB
ScreenshotLZD is a new compression program specifically developed to achieve very high compression and decompression speed. It's typically 3 times faster than BZ and uses less memory, while often providing slightly better compression. Although it is fast, LZD provides very good compression ratio, especially on small and complex objects (e.g. games). For even more speed, a compatible derivative named FastLZD is also provided.

PK   (details) 48 ENG   3 KB / 2 KB
PK is an LZ class compressor. The main difference to RF is that PK uses 3-nibble offsets to matches instead of 2 and PK also uses a speedup method for finding matches. Obsoleted by BZ, but included here because decompression is faster.

Stacker4x 1.2   (details) 49/50 48 ENG   9 KB / 2 KB
ScreenshotStacker4x compresses and decompresses on the fly all data handled by the user, so that the user can enjoy the benefits of compression without thinking about it. Everything is fully automated and once the library is installed, it will activate itself and intercept calls to STO and RCL. Compression is provided by FastLZD, and it is very fast (5x-10x faster than BZ), to the point of being hardly noticeable for most objects.
