Anyone that has Black Ops, please try and install the debug updates (installing them manually of course, extracting the .pkg using fastpkg.exe) and see if that gets the game to run.
Let's hope this'll work, but on the debug links page they are labeled as 3.50. Despite being debugs, could the EBOOT.BIN still only ask for 3.50
If you've tried to run the game before doing this and been asked to update do this extra step:

It crashes when going into multiplayer though, so not even split screen or LAN (which can be turned into online via XLinkKai) will work at the moment.
