Coincidently, a new PSP firmware will be released around the same time as the new slim PSP (PSP-2000) hits the stores. The update may contain additional features for both models, but will mainly fix a bug that causes PS1 title Biohazard Director’s Cut to malfunction on certain game modes. The new firmware, possibly 3.60, may contain features for the new PSP model to allow the additional functionality the model allows.
The official statements reads:
"If you are using PSP with OS version 3.52 to play PlayStation classic game Biohazard Director’s Cut which is purchased at Playstation Store, there might be malfunction happening in the ORIGINAL, BEGINNER, and ARRANGE modes.
The malfunction is expected to be fixed in the next PSP OS Update (tentatively scheduled in the beginning of September). The game is running properly on PlayStation 3. We apologize for any inconvenience this might have caused.
Please kindly be advised to update your PSP to the latest version once the next software update is available."
