I have a model one sega cd. I haven't played it in years,but I had the urge to play eternal champions. So,I dusted it off and cleaned the contacts and hooked it up to the tv and it played beautifully. I took a break from playing and decided to clean the laser with a cd laser cleaner disc. I then continued to play games with no problem. The next day I boot the system up and it won't read my games.

With that said,it does play the cd+g 'rock paintings' disc and music cd's without a problem.

Any idea as to what is going on?

Thanks
