That error shouldn't have an impact on running a N64 game - can you please post the entire /dev/shm/runcomamnd.log file ?

Do you also get an error if you install the lr-mupen64plus-next N64 emulator and run the game with it ?

Did the op get this fixed? This happened to me and it was (doh) because I'd just moved everything over to a new flash drive but I'd forgotten to copy the kickstarts across...

This does sound like a kickstart issue - either the required files aren't there or they're named wrong.
