zx7, an optimal lz77 / lzss data compression utility with companion z80 decompression functions, has been updated to optionally perform (de)compression from the end of a data block and to allow optional use of an uncompressed data prefix to "prime" the (de)compression. The former should aid with decompressing data into tight spaces and the latter should help improve compression ratios especially for small individual data blocks.
