Never mind, I got the config from the Vlasovsoft ZIP file! For reference, here it is:
Code:
menu_item :main :Vlasovsoft :cmd_spawn :quiet:sh /mnt/onboard/.adds/vlasovsoft/launcher.sh
(It gets installed automatically, but I already had the Vlasovsoft files from an earlier installation so I had to manually add the entry to NickelMenu)
