3 PS One classics from the PS3 online store have been removed ue to technical flaws.

Crash Bandicoot 2, Spyro 2, and MediEvil have all been removed while Sony tries to fix mainly emulation issues.  "This investigation is highly technical and requires some time to work through," wrote a Sony official response to a message board discussion on Playstation.com

Customers who purchased the affected games will receive a message from Sony within the next 10 days, according to the same message board post.  They also say the removal of Crash Bandicoot was mainly precautionary, adding that the title should be available for download again soon.

Sony has not commented on when these titles will be fixed.
