incog made a mistake when he updated the list, apparently. update to latest svn (rev. 7972) and you'll be fine
alternatively, as a temporary workaround, you can move out the supracan.xml file from the hash directory and use the full path of the cart to load the game(s)... you will need the amended softlist from rev.7972 to use shortnames, in any way, but if you e.g. cannot access svn from the computer you are at the moment, the workaround is fine.
