I was using 3.02 OE-A and I found these problems:
Sonic Rivals game save can't be loaded..(it was loaded with devhook emulating 2.71)
but it can't with devhook 0.50...
I upgrated to 3.03 OE-A2 and the problem is still here..
looks like with 3.xx firmware there is a bug..

same problem with loading Mortal Kombat Unchained and Pro Evolution Soccer 6 Option File

Has anyone else noticed this "bug" ?
