sprintf does exist in the kernel libc, what the real problem is you are converting floating point values around which isn't getting linked in (that function is part of libgcc it extends 32bit floats to doubles). However the kernel libc doesn't support float formatting anyway so I wouldn't bother co...

Don't you mean Lynx? Not Links?

And I'm pretty sure that's already been ported in some form or another, if my memory serves me correctly.

This is because by default, the eLoader replaces unrecognised NIDs with a call to a generic 'return(0);' function. So if the appropriate module for a function is not loaded, then calling that function will appear to succeed, but the expected action will not have been taken. You can verify that this...

That's what would happen if you had the encryption key wrong. Did you change it for SOCOM? The samples are set up for GTA. Yea I compiled my own eboots to decrypt/encrypt the SOCOM save file, as well as the socom online update file in the SHARED save directory. They work perfect on my friend's 2.0 ...

You were right.

They do not work correctly.

They will say that they succesfuly wrote data and execute correctly, but the output when encrypting or decrypting is not correct.

I'd be very surprised if they actually work though, since the appropriate module is not loaded unless running in VSH mode. Hmmm I'll try to decrypt a SOCOM FTB save and see if the results are correct now. Before I just tested it and it went through without error so I assumed it was working. I'll ge...

Just wanted to know that these samples now work on 2.01, 2.5, and 2.6!

The new GTA eLoader version (brown ale) supports the VSH NIDs.

You can't use the eLoader for the current encryption/decryption eboots, since they needs to be run in VSH mode (according to the top post by jimparis) and the eLoader runs in GAME mode. // Ditlew Is it possible to modify these samples to run in game mode? Or are some features used only availabe in ...

The Fanjita Beta GTA eLoader is now released.. Now I've run into some problems. These ecrypt/encrypt samples will not run on a 2.01 PSP using the GTA eBoot loader.

thnx for all the replys. I don't see why you are questioning what to use as a mic input.

I don't see why you are questioning what to use as a mic input. Sony has already realeased an official headset with a flexible microphone, and it works in online paly with SOCOM Fireteam Bravo. It retails for 20$, but because of poor promotion, a quiet release, and lack of supports except for one ga...

What has happened to the simple user friendly GUI decryptor/encryptor? psp123 was working on one, and I think he was mostly done, but I haven't heard from him lately. It looks like another one was recently released here but I believe it's only for old format saves at the moment. I found GTA's key h...

Another thing which I've been wondering.. Is this exploit in all 2.0+ save files, or all save files in general? If I do a pattern search of the hash on the GTA dump will it turn up, so I know where to find it on other game dumps? Or will someone explain that please, I can't find any documentation on...

They should just meet somewhere in the middle and instead of fighting the homebrew scene, patch their exploits but create a JVM that cant access the UMD or flash, and has other restrictions to prevent piracy, but is otherwise intact.
