After applying several patches to the ownz' released HDL, and using it through the MC exploit, I have realized that although the already installed games work fine, I can't install any more games using it. When I put an (original) PS2 game in the drive, and select 'install', I get an error message saying that the disc in drive is not a PS2 disc. If I try to install that same disc using either HDadvance, or the original HDLoader disc, it installs fine.
What's the problem? How can I patch the ownz' HDL to make it possible to install games?
