*Reduced HDD read time out to 25 seconds *Added two disc feature (Extracted format is unsupported) Use the latest DMToolBox (0.3 or higher) to install your two disc games This will be the last version for some time, since I'm moving my focus to other things. Always remember; Impossible is nothing! git-svn-id: svn://localhost/Users/andi/Downloads/code/DML@34 be6c1b03-d731-4111-a574-e37d80d43941
