This is an application to downgrade a ta-082 unit running 2.71 firmware and HEN-D to 1.50, although theoretically can downgrade to any version, but only 1.50 has been tested.

 

The application, at the moment of writing this readme was tested in 5 psp’s, with 5 success. As always, this kind of application have risks, this one in concrete write to idstorage area of nand.

 

READ CAREFULLY THE INSTRUCTIONS AND DON’T SKIP ANY STEP

 

Instructions

 

* Copy the UPDATE and idstoragechange folders into /PSP/GAME/

* Get the official sony 1.50 eboot and put it in the /PSP/GAME/UPDATE folder with the name of UPDATE.PBP

* Run HEN-D if you are not already running it.

* Execute the idstoragechange. It needs 75% battery. It will change some keys of your idstorage needed to downgrade the ta-082.

* The program will exit to the XMB. Now execute the generic downgrade, which will show in the xmb as “Update X.YX” in the psp language.

* The generic downgrader will also need 75% battery. IT will downgrade your psp to 1.50.

* At the end, it will ask you to press X to restart the psp. Do it.

* If all went fine, you’ll receive a blue screen telling you to press O. Do it, and reenter your settings. Welcome to 1.50.

* If things didn’t go that fine, you’ll have a non-functional psp, aka brick. You accepted that risk, remember.

CWCheat for PSX emulator on PSP

weltall has emailed us his latest CWCheat for POPS. You can now enjoy cheating all your PSX titles under 3.02 OE PSX emulation! It does require little modification to get known cheats working; but it’s easy — samples are included. Check out “HOW TO CONVERT PSX AR-GS CODES.txt” for details on that.

 

0.1.6 REV. C changes for 3.02OE/POPS:

 

* this is a special build only for pops (PSX EMULATOR)

* removed usb support as usb prxs aren’t loaded in pops mode, maybe they can be loaded but to avoid flashing requirement i preferred this way

* removed all umd imports (same as above)

* remapsp although is still there (and seems to do something) is reported as not working it disables game input

* ID is forced to POPS

 

Keep in mind: this only works for 3.02 OE as the PSX emulator can’t be used with DevHook.

 

All other features remain fully intact, this means you can:

 

* cheat in your games (the db and the config are loaded from ms0, if you don’t have them it will still work only it will go for default config and you will have an “empty” db) the ID of the pops emulator is POPS.

* CHANGE THE CPU CLOCK IN GAME WHEN YOU WANT IT WITHOUT REFLASHING EVERYTIME!! this means that you can put a default cpu/bus clock that will be set when loading in the config file (change the cpu clock in the menu and save the config in the config menu) but also you will be able to change in every moment and without touching the flash the cpu/bus frequency!!

* my screenshootbmp mod which uses volatile ram to do the screenshoot stopping the game for less than one sec!

* standard screenshoot version

* brightness changer which uses the screen button (what you use to change brightness normally) it works up to the 4^ level

The sound test of MVSPSP was deleted from the source code of the latest version (Because the sound emulation was changed). If necessary, please download the source code of 20061222(CPS1,CPS2 1.64 / MVS 1.63).

If anyone wants to download source code and binaries for CPS1PSP 1.66/CPS2PSP 1.66/MVSPSP 1.63/NCDZPSP 0.45, you'd better do it now. Get them HERE.
