These cartridge dumps may be used with MESS 0.131 and later. RPK files are ZIP containers. You can find information about the cartridge in the file meta-inf.xml included in the container. Do not unzip for use with MESS. You can plug in different cartridges at the same time. They can be selected by the "Review Module Library" feature. If modules do not show up in the selection list (specifically Atarisoft), put the DIP switch "Active cartridge slot" to "1" and try slot 1. Programs may crash in slots other than number 1. Parsec is known to run in slot 1 only.
