After making quite a few coasters I stumbled on a thread that indicated that all the files created by cd_dvd rom generator need to be merged. I follow Winning11's script to the letter for NBA Street 3. When I tried to boot the backup I received the message not a PS2 disc. In short if the cd_dvd rom gen program creats xxx.000, xxx.001, xxx.002 all the files need to be merged. example copy /b xxx.000 + xxx.001 + xxx.002 xxx.IS0. Hope this helps with the fustration level. Winning11's script is good,but it leaves out this info. No criticism his script is right on the money just not complete for us lesser thinkers.
