[-h, --help] [-V, --version] FILES...

Please note that this utility is not able to read a generic file. Itcqs granted to be able to read only the files generated by the AdvanceMAME emulator.

To compress the files this utility uses the following strategies:

*

Remove all ancillary chunks.

*

Concatenate all the IDAT chunks.

*

Use the 7zip Deflate implementation.

-l, --list FILES...

List the content of the specified files.

-z, --recompress FILES...

Recompress the specified files. If the -1, -2, -3 options are specified itcqs used the smallest file choice from the previous compressed data and the new compression. If the -0 option is specified the file is always rewritten without any compression.

-0, --shrink-store

Disable the compression. The file is only stored and not compressed. The file is always rewritten also if itcqs bigger.

-1, --shrink-fast

Set the compression level to a"fasta".

-2, --shrink-normal

Set the compression level to a"normala". This is the default level of compression.

-3, --shrink-extra

Set the compression level to a"extraa".

-4, --shrink-insane

Set the compression level to a"insanea".

-f, --force

Force the use of the new file also if itcqs bigger.
