(adsbygoogle = window.adsbygoogle || []).push({}); Okay Ill admit this is something that A LOT of us want, well today I tried patching the hash and every theory that people have came up with for modding the gamesave. Now I really dont think the hash is CRC32 or whatever people have been thinking first off lets make sure we are all on the same page meaning that we all agree that the games checksum is located somewhere(usually the SVG) not somewhere on the systems RAM(memory) when used with pointers would make it more secure. In this case we think its in the game save memory itself.

The reason I think It might not be a CRC32 hash is because I did try modding the savegame files including the GRADO_MP.PRF (prf I believe stands for PlayStation readable file -or something like that?) meaning the PS3 reads it based off its hash and since the HDD doesn't have it then the gamesave must. Whats in the gamesave that could possibly contain the hash? Well there is only one thing and that is the Savegame.SVG.

Now let me explain what I did and what I found, okay first off I went with the CRC32 route and I took my old un-modded hash recorded it then I modified several parts of my gamesave and the grado files then I went back and I re-applied the old hash patching the new bytes so in theory it would allow me to use the modded values and client variables.... Well infact it did! I was able to copy it over to my PS3 without really any issue, nor error etc but nothing was applied ingame I am not totally positive if this was on my part of the lack of knowing the misleading names of dvars etc but I thought it was able to read the hash okay so it must be something.

Well Idk if its totally true but I am currently looking into something which I call silent patching which has been brought up once before. If the checksum and hash are not identical to the original then it might just patch it to the original data hash that was there before making everything that you modded almost useless.

This is really more of a discussion then how to do it as there are already crap loads of stuff on that but really I dont think we should be patching the GRADO files, I think we need to look @ the svg itself and modify it to work, also the reason HSx9 left that first line the game in the SVG when he modded the LAN profiles.

Well Ill keep you guys posted, and btw EVERY file in the entire gamesave(the whole folder) has their own hash including the PFD, and the SFO.

Also for all you guys wondering, yes I did mod somethings

(picture comming soon once its off the camera)


So discuss your findings and maybe we can finally figure more stuff out....

Thanks I am going to post up a thread about everything of advanced game saving modding, most people will need to ask around as most people dont have a clue what non binary stuff is.

alright so can you give me some links to all those programs you said we would need?
