When an application was ended with the red LED indicator of
PlayStation(R)Eye on, although it went back to the system software,
the red LED indicator was still on. This problem has been fixed.

[Known Issues/Restrictions]
<Check menu in the Game column>
- Validation of a media or the file system itself cannot be performed
from the Check menu in the Game column.

When submitting a master disc, make sure to verify the disc that no error
is present using the Disc Image Generator for PlayStation(R)3 or
the Disc Image Checker for PlayStation(R)3.

- When performing the check from the Check menu in the Game column,
if the number of result files exceeds approximately 80 to 100 depending
on each check item, the file entries of the root directory in the USB
mass storage run out and the subsequent check result files may no
longer be stored.
In such case, move the check result files to another directory.
