I am having issues launching arcade games properly next to console systems.  I use Retroarch for a great deal of the home console emulation throughout the 80 & 90's.  (ease of use & uniform controls)  To save space, I have most of these games zipped.  The problem occurs having the emulator retroarch selected to unzip games before startup.   Realizing that i would need to rename the emulator (if I wanted to use the same emulator(Retroarch)) or use a completely different emulator to run Arcade game I did just that.  I made a new emulator called "Retroarch Arcade" and made sure to have the unzip game before startup to be unchecked.  (The wording on the checkboxes is not 100% as I am not in front of my emulation machine)   I was met with the same results.  No matter what I tried to do the games would try to unzip until I changed the original Retroarch emulator to not unzip games.  I even made sure that "Retroarch Arcade" was the default emulator for Arcade/mame.   
 
	     I bare the same results even trying to use differnt emulators like mameui64 and mame.   I apologize for the sloppy writting.  Currently at work.    @Jason Carr
