Compressed ROMs in LaunchBox (using Demul as example)

Using a zipped/compressed ROM in emulator through LaunchBox.

Allows you to save hard drive space, but does take a little longer to launch each game (about 20 seconds per 500MB depending on CPU and hard drive speed.)

You must have the setting checked to “Extract ROM archives before running” in the emulator setting inside Launchbox.

Example: Tools, Manage emulators, Demul (or whichever emulator) then Edit. Bottom right corner is a checkbox for “Extract ROM archives before running”. In this image it is NOT checked, but you’ll need to check it and click the OK button for it to work.ExtractRomArchive

The audio is a little choppy in the game start…this is due to the slower laptop I was editing on and not indicative of the game play.
