I traded in my version 3.0 at gamestop for a 2.71 with board TA-082. Successfully downgraded than upgraded to 3.03 OE-C. I created an ISO file in the root directory to play backup ISO images. Valkirye Profile - Lenneth, and Sonic Rivals both work, but when i tried to load the Sims 2 pets and Medal of honor the game would start to load, then gives the message "The game could not be started (80020148)" My configuration in the Recovery mode is: Hide corrupt icons:enabled Game folder homebrew :1.5 kernel autorun:disabled Use no UMD:enabled Fake region:disabled Free UMD region:disabled. I then tried putting in the metal gear portable ops UMD and several other UMDs I own and disabled no umd. didnt get an error but instead am still staring at a black screen an nothing ever happen. thanks much.
