PGDfile.raw.decrypted

[El_Maco_Destructo (oO)p /BOOM/]

I was reading through the issues on Github and apparently PGD file support (not decryption) has been added / merged.

So is there a way to 'bind' a specific PGDfile.raw.decrypted to a game on PPSSPP?
Would like to try out some games for which I've had the PGD decrypted.

Thx in advance

No, there is decryption already, although it doesn't seem to work 100% yet. There is no support for external ".raw.decrypted", for now you have to replace the file in the iso if you really want to try that.

And the specific file in the ISO would be INSTALL.BIN, right?

EDIT: Just patched a game by replacing the PGD; it didn't run before, but now it runs perfectly on PPSSPP 0.7-16.
EDIT: Only ran fine the first time. Second time and thereafter, somehow it will always reset to menu.

Is this the problem you're talking about?



If so, can this be fixed using ISO_TOOL on real hardware?

If you have the decrypted PGD (*.raw.decrypted) , simply rename it to INSTALL.BIN and swap it with the one inside the Game-ISO under

PSP_GAME\INSDIR\

You need an ISO editor / builder to do this, I was using WinISO.

Btw. the game is Dunamis 15, a japanese VN.

Ok.. Tnx for answer man. But, i can get decrypted PGD (*.raw.decrypted) only on real PSP?

I let the game run in JPSCP and took the decrypted PGD from its temp folder.

I like that idea very much, solves any decryption problems until this emulator can stand on its own 2 feet, so to speak

Yeah man, until PPSSPP isn't able to decrypt every PGD file, we can use JPCSP to decrypt game and do like El_Maco_Destructo said.

I just had the same idea and Shining Ark seemed working!
I used UMDGEN and v0.6-900.

Can someone tell me some good PSP games that use PGD encryption?

[livisor]

Naurot Ultimate Impact,how can I check if a game is pgd encrypted?

Run game in JPCSP, and if u get *.raw.decrypted file in tmp folder then it's encrypted. I know only that way. Maybe it can be checked with UMDGen, but im not sure. Then u rename *.raw.decrypted to INSTALL.BIN and replace with INSTALL.BIN in games iso, and save to another one. Then game should be decrypted. INSTALL.BIN is in PSPGAME/INSDIR folder in iso file.
But problem is, there is no INSTALL.BIN in Naruto Ultimate Ninja Impact. How, i don't know.

[tamatom]

The file you should replace is in INDIR and a little larger than what JPCSP makes. Maybe data.bin or install.dat...

I used UMDGEN to replace the data which JPCSP had made.
