# snapconv(1)

Sinclair ZX Spectrum snapshot converter

## NAME

snapconv — Sinclair ZX Spectrum snapshot converter

## SYNOPSIS

**snapconv** \[ -c \] \[ -n \] \[ -f \] *infile outfile*

## DESCRIPTION

snapconv converts between ZX Spectrum snapshot files.

## OPTIONS

- *-c*

  specifies that all data in the output snapshot should be compressed, even if that compression will result in a bigger file than if some data is left uncompressed. This helps compatibility with some buggy programs that can only read entirely compressed .z80 files.

- *-n*

  specifies that the output snapshot should be uncompressed.

- *-f*

  specifies that the A and F and A' and F' registers should be swapped. Version 0.5.0 and older of  [*libspectrum*(3)](/libspectrum/3.md) had a bug that resulted in these registers being swapped in SZX  snapshots only. Version 0.5.1 and newer of [*libspectrum*(3)](/libspectrum/3.md) automatically recognise these snapshots and correct the problem, but this flag is necessary to fix some snapshots created by *development versions only* of [*libspectrum*(3)](/libspectrum/3.md) which had the bug fixed, but cannot be distinguished from snapshots containing the bug.

- *-h*, *--help*

  give brief usage help, listing available options.

- *-V*, *--version*

  output version information.

- *infile*

  specifies the snapshot to be converted. This file can be in any of the snapshot formats supported by [*libspectrum*(3)](/libspectrum/3.md).

- *outfile*

  specifies the output snapshot. The format will be determined by the file extension and can be in any of the formats [*libspectrum*(3)](/libspectrum/3.md) supports for output.

## BUGS

None known.
