The only newer game I can test for now is DOA5, I know for a fact the eboot as never been modified and even it is giving the 80010017 error
I tried games like Unreal Tournament 3 and a few other OLD ones (like pre-3.55) and they do work from multiman but anything with a 3.55 eboot doesn't work
Just NOTHING else works...
