IMPORTANT NOTES: If the game doesn't work after unrar, do the following:
1. After unrar, rename the ISO file to "strikeforce.iso". 2. DO NOT set umd mode to SONY NP 9960, any other mode will do. (Press select on XMB and set UMD ISO mode: M33 Driver 3. If you have tried both of the above, and it still doesn't work, try to upgrade to the latest firmware version.
