Dopo la demo rilasciata soli 2 giorni fa e limitata a 10 minuti di funzionamento, sul sito di MPH è apparsa la versione Finale del Game Loader dedicato a tutti quei giochi che richiedono espressamente firmware superiori al 1.50 e non giocabili con il consueto Trick del cambio di versione.
Le istruzioni per l'uso rimangono sostanzialmente identiche, è stato solo ottimizzato il codice e rimosso il limite dei 10 minuti.

MPH 2.00 Game Loader for 1.50 (gta version)

Before using this program, please read what follows :

- The loader requires iso of the game to run, that doesn't want to say that you can use the iso if you don't have the original umd.

- You will need umd emulator, umdgen and a tool called DecryptPRX which is not other than a modification of the psardump tool of psppet.


CREDITS :

THANKS TO :

- Tyranid for his beautiful psplink tool
- PspPet for his psardump known of all
- All pspsdk team
- umdgen and umd emulator authors


Iso modifying :

You will need the iso of GTA to be able to continue, I will not give the means of obtaining it, therefore don't ask me on this subject.

Once the iso obtained, it will be necessary for you to extract all the files from the iso (use umdgen).

Then, place PRX2_0_0 folder (in PSP_GAME\USRDIR folder) has the root of your memory stick.

Execute then DecryptPRX, it will create in PRX2_0_0 folder somes files with dcr extensions, remove all the prx files and replace with the dcr files created (remove the .dcr extension) (to replace the crypted prx by the deciphered prx).

Then, recreate the iso with all the files which you had extracted AND PRX2_0_0 folder containing the deciphered prx.

Now you have iso on the good format


Firmware 2.00 installation :

You will need firmware 2.00 in files format, use psardump to obtain it or my firmware launcher and use the function to install a firmware.

Once that you have the files, create the mphgameloader folder has the root of your memory stick and copy flash0 (kd, vsh...) and flash1 folders inside.


Loader installation :

Install loader (MPHGAMELOADER) like any psp application (PSP/GAME/) and copy mphloader.prx in the mphgameloader folder.


You will have the following structure of folders/files :

Memory stick
|
|- mphgameloader
|
|- mphloader.prx
|
|- flash0/ (with sub folders and files)
|- flash1/ (with sub folders and files)
|
|- PSP/
|
|- GAME/
|
|- MPHGAMELOADER
|- MPHGAMELOADER%
...


Launch gta :

Run umd emulator and choose gta iso.

Launch then MPHGAMELOADER

Welcome to the gta world, 1.50 is not dead ;-)

Allo stesso tempo è uscita una nuove versione di DecryptPRX, giunta alla 1.02, che aggiunge il pieno supporto alla Decryptazione di MegaManX.

DecryptPRX (Version 1.0.2)


Decrypt the prx placed in crypted folder (root of memory stick), the original prx are overwritten by the decrypted prx.

- Now, can decrypt prx on megaman game

This program is a psar Dumper .02a mod, original program by PspPet.
