Although you may be not currently using this, _HellDashX_ has rolled out an update to his 3.72 HX custom firmware.

Changes:

• Contains the latest 3.71 M33-3 changes.
• The file vshctrl.prx IS NOT the one from Dark_AleX,It’s coded by me after reversing it 100%.
• The exported functions from the vshctrl.prx are the same like the 3.71 M33-3 SDK,plus two more:
  1. int vctrlVSHEraseIsoCache(con st char* path) -> Lets you erase the cache from an iso created by the CF. If the parameter is empty “”,it will erase the whole cache,not just from one iso.

     The iso cache will not be created in the memorystick.It will be in the flash1.I made this function to test stuff faster.Gives a 0 if it deletes correctly else it will give -1.

  2. int vctrlVSHMakeCFDirs() -> Lets you create the custom firmware directories,in case you dont have them(GAME150,GAME372…) in the memstick.Good if you have a pandora memstick and cant format the ms but dont want to create all directories by hand.
• Only one vshctrl.prx for both psp models.In 3.71 M33-3 and others there was a vshctrl for the fat and an other one for the slim because they have slight changes.This new vshctrl will detect if you got SLIM or FAT.
• Other non important changes in the code.

There are two updates included: a mini and a full. The mini will update your PSP from 3.72 HX-1 to 3.72 HX-2. The full will update your PSP from 3.71 M33-1/2/3 to 3.72 HX-2.

Place the updater in the PSP/GAME/UPDATE folder. An official 3.72 EBOOT.PBP is required for the full update. Rename it to 372.PBP and place it with the rest of the files. Make sure you run the correct installer!

As for the 1.50 kernel addon, Dark_Moon has reversed a small part of Dark_AleX’s kernel addon to release this.

Instructions:

1. When you have installed the firmware 3.71 m33 and the kernel addon download this file and open MS_ROOT. Then copy the PSP folder to the root of your memory stick.
2. Run the app, and press Square. Now the program will start to dump the addon. The dump is on ms0:/psp/game/update/km. Copy the km folder to your hd.
3. Install 3.72 HX. Later copy again the PSP folder that contain this app to the root of your memory stick.
   Connect the USB (Flash0) and copy the backup done before in the root of the flash0. Run de app again and press X. It will copy the reboot150.prx and all will be done!
