I want to ask a question regarding the remote play function of the PSP!

Is it a must to update the PSP firmware to the latest in order to remote play the PS3? I am using the 3.71 M33-3.

I just found out how to configure the PSP CFW 3.71 M33-3 to enable to remote play!
U dun need to upgrade to 3.72!

Took me a few day surfing the web to find out how! The source of the guide i also not sure already there are a few webpage have it posted up! I think u may find it in PSP hack or any site that has modding PSP
Here is the guide:

1. Dl the latest 3.72 firmware (go to the sony official site)
2. Dl M33_NEWPSARDUMPER (dark alex site got it)
3. Connect ur PSP with the USB
4. Rename the the 3.72 firmware to EBOOT.PBP and place it in the root menu of ur memcard (just in the memcard not in any other folders)
5. Unzip ur M33_NEWPSARDUMPER and place it in the memory card's\PSP\Game folder
6. Disconnect ur PSP from the PC and run the NEWPSARDUMPER from ur PSP memcard
7. It will enter a command prompt format with a few selection, Press SQUARE button to decrypt the 3.72 firmware (here will need to wait for awhile)
8. After it is done reconnect ur PSP to the PC and copy the premo_plugin.prx (fo\vsh\module) & premo_plugin.rco (fo\vsh\resource) and paste them in ur PC.
9. Now u may delete all the files ur paste in ur PSP earlier since they are useless now! (Dun disconnect ur USB cable first, there is still further usage)
10. Turn off ur PSP and turn in back on to load into PSP recovery menu (do so by pressing the R Button while Switching ON the PSP)
11. In the recovery menu select "advance" then select the "Toggle USB (flash 0)"
12. Now ur PC will pop up a windows which show u the contents just like the folder decrypted earlier
13. Paste the 2 files ur copy earlier to replace the premo_plugin.prx and premo_plugin.rco (locate in the same folder u copy them from)
14. Now u may Exit the recovery menu, do so by select the Toggle USB (flash 0) ->Back -> Exit
15. Ur psp will restart into the XMB menu, u are now able to remote play ur PS3 now!

I did it and it is confirm sure working for me! For those who want to tried feel free to do so!

Yah lithum-ion battery should be charge like the way they mention! But they are still a lot of ppl dunno about it! They tend to charged it when it has totally depleted of energy! They are shortening their battery life instead of expanding it!
