Official improvements PSP4000 hardware improvements are as follows
One: using two CPUs
CPU PSP CPU (working frequency 1-333MHz) dual CPU (45 nm)
2. Firmware system: 9.0 will be released on September 9, 2009, and new firmware 9.9 will be released at that time.
Change the switch to a button switch.
Third, the new power-saving technology makes PSP4000 more power-saving, and the basic service time is increased from 8 hours to 12 hours.
Four: the latest patented technology charging time is 3 minutes (it can be charged to 80%). It takes half an hour for users to charge faster (this technology is unknown at present and may not increase).
Five: Eliminate the scanning lines on the screen. Users can hardly see the scanning line of PSP4000.
Six: shell improvement adopts brand-new aluminum alloy shell and adopts toughened technology shell.
Seven: Join Bluetooth transmission technology and PS4 to transmit files (and PS3 can also be linked). Note: On September 9th, 2009, PS4 and PSP4000 were released at the same time!
Eight: Add an external handle interface to connect PS2 and PS3 handles.
PSP4000 software changes
One: video recording function is added, that is, PSP game pictures and * * blocked content can be recorded as pictures.
Two: add CPU** blocking content * * in firmware.
Third, the system is improved to save more electricity. Because of the new CPU process (45nm) technology (half of the original PSP 1000 2000 3000), the game time is almost twice as long as that of the previous console.
Four: the system security is increased and cannot be cracked. Adopt new anti-crack technology! ! Unable to install homemade system, run pirated games and homemade software.
Five: The CPU frequency can be directly adjusted under the system, and two CPUs can be adjusted at the same time.
Six: it is faster and smoother for two CPUs to run games at the same time in the default frequency environment.
Seven: Add the PS2 emulator plug-in and directly run the game files converted from PS2.
Eight: PS4 host can be connected to PSP4000, and the game screen of PSP4000 can be directly controlled by the handle on PS4 host, which can be used as the display screen of PS4.
Nine: add MSN chat software to the system firmware.
Ten: It is more playable, and you can exchange files and enjoy resources with the mobile phone with Bluetooth function.
Eleven: The improvement of operation speed will improve the performance by about 50%.
XII: Increase video playback without flipping (real playback function may not be added in PSP4000, but may be added in PSP5000).
Thirteen: wireless Bluetooth handle technology (PSP4000 special handle needs to be purchased) was launched at the end of 2009!
Fourteen: The new PSP4000 will add special online games! The number of people in each room in the game has increased to 16. Interactive enhanced games include (monster hunter PSP online version Dream Star PSP online version True Three Kingdoms unparalleled PSP online version unparalleled serpent PSP online version, etc.
Fifteenth: The firmware system adds recording function.
Sixteen: add voice PSP game!
XVII: Add mode options (PSP4000*** has two options: basic mode and game mode).
PSP4000 Standby Time Announced
In PSP4000 basic mode (CPU frequency11,that is, the standby time when two CPUs are running at the same time is about 8- 10 hour).
In PSP4000 game mode (CPU frequency is 222, that is, the standby time is about 6-8 hours when two CPUs are running at the same time).
You can run PSP games in basic mode, but you can't start recording games. You can run basic functions such as music and video files.
In the game mode, you can run the game recording function of PSP, play PSP games normally, and run all the functions under the firmware system.
Finally, I personally think 12: increase the video playback without flipping (the real playback function is impossible because Sony is pushing his UMD movie ~
