It's granted to be able to read only the files generated by the AdvanceMAME emulator. <p> To compress the files this utility uses the following strategies: <ul> <li> Remove all ancillary chunks. </li> <li> Concatenate all the IDAT chunks. </li> <li> Use the 7zip Deflate implementation. </li> </ul> <h2><a name="3">3</a> Options </h2> <table width="100%" border="0" cellspacing="0" cellpadding="2"> <tr valign="top" align="left"><td><strong> -l, --list FILES... </strong></td></tr><tr><td> List the content of the specified files. </td></tr> </table> <table width="100%" border="0" cellspacing="0" cellpadding="2"> <tr valign="top" align="left"><td><strong> -z, --recompress FILES... </strong></td></tr><tr><td> Recompress the specified files.
