DESCRIPTION

The main purpose of this utility is to recompress png files to get the smallest possible size.

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.

*
Use the 7zip Deflate implementation.
