I'm using the latest version of ScummVM and it doesn't seem to recognize "Ringworld: Revenge of the Patriarch". This was printed to the command line:
The game in '/export/scumm/other/ring' seems to be unknown.
Please, report the following data to the ScummVM team along with name of the game you tried to add and its version/language/etc.:
{"tsage.rlb", 0, "d80b5ec35695971a0a31f1322c1f7f93", 32235},
{"ring.rlb", 0, "c7bfd0c2428c639cd9ff5531b3b26763", 33692},
Ringworld not recognized
