NAME

       rzxtool — Modify Sinclair ZX Spectrum input recording files

SYNOPSIS

       rzxtool  [-dblock number] [-eblock number,filename] [-iblock number,filename] [-u] rzxfile
       [outfile]

DESCRIPTION

       rzxtool allows some simple  modifications  to  be  made  to  Sinclair  ZX  Spectrum  input
       recording files: blocks can be removed, snapshot data can be extracted or snapshots can be
       inserted into the file. The file can also be uncompressed.

OPTIONS

       -dblock number
              The block number specified will be deleted from the file. Block  numbers  start  at
              zero  and  ignore  any  “creator information” blocks in the file. The modified file
              will be written to outfile.

       -eblock number,filename
              The snapshot in the specified  block  number  will  be  written  to  the  specified
              filename. All snapshot formats supported by libspectrum(3) are available.

       -iblock number,filename
              The  snapshot  specified  in  filename  will  be  added to the file at the position
              specified by block number.

       -u
              When outputting an RZX file, this option causes the  input  recording  data  to  be
              output uncompressed; if this option is not given, the data will be compressed using
              zlib(3).

       rzxfile
              specifies an input recording file whose contents are to be modified.

       outfile
              specifies where the modified input file should be written.
