If you're able to extract your save game from your XBox, zip all the files up and email them to me. I don't have an XBox.

 

From what I've seen, it looks like KSE won't need much modifcation to work with KotOR2 savegames.

:Open2: You know the potential this could raise goes beyond just KSE with the savegame info off of the XBOX we could forward this on to Fred as well and have KOTOR Tool ready for the update as soon as KOTOR2 hits the stores for PC.:D

What T7 said.

 

The knowledge-base of this forum is largely PC based so if there are xbox afficianados who want to make a difference in this forum-- we need to know the directory structures on the xbox for one. Tutorials on how to extract files is another need. Then darkkender's idea could come true.

You'll need a mod chip to access the Xbox's internals and all that. If you do that never try to logon to Xbpx Live, for Microsoft has implemented things to that service when Halo 2 came out. So if you do this(get a mod chip and edit stuff)and go to Xbox Live, you'll be banned from that service. :(

i know someone who tried to "softmod" his xbox and he said the same thing, that you shouldnt do that if you wanna use it.

 

which is kinda dumb, cause the xbox got so much potencial.. specially with the link to the internet.

TK, I can get you the saves you need. I have already looked at them and they are set up the exact same way KOTOR 1 was. There is little difference in the main structure of the PC files of kotor and the xbox except for a few files and of course the executable file so that will not be an issue. I used the ERF editor to mod the save to give me lots of xp and money but there are codes you need to resign an xbox save after it has been modified and of course they are not the same codes kotor 1 used. If there is anybody that understands hex real well and can decipher the algorithim used to generate the key I could get them the files they need to break the algorithm so that xbox users can use modded saves. If you want those files TK I will need your email address.

It looks to me like the .sig files are HMAC SHA-1 keyed files. They are 160-bit files (an SHA-1 characteristic). The key is probably a registration key that came with the game or is somehow unique to the Xbox in question.

Further update:

 

I'm researching what is required to generate the key for re-signing modified savegames. It is not trivial. I'll keep you informed.

Last night I tried a brute force tactic against the savegame.sav file using 5 of by best guesses... but to no avail. No results and the numbers keep chugging. This assumes a single keyed hash on straight data (no hashes of hashes).

You can have a switch on the front of the Xbox which turns off the Mod Chip. This obviously means you have to play originals only and can't do any of the other stuff the Mod Enables you to, but you can play Live

without risk of your Xbox being blocked from the Service.

Hmm, I'm curious here. Would an Action Replay save be salvagable for this exercise?

 

Near as I can tell it should be the same format as on the box hardware itself.

And if they work, I can provide some TSL xbx saves, (there's also a number of XAR saves available from codejunkies.com or gamefaqs.com if those are usable).

I've done a few modded test saves for a guy who does my testing. He has no modded xbox and he uses an AR... they work fine. AR saves are completely salvagable.

 

If anyone needs a save with something specific for info purposes, I can do it, no problem.

I downloaded the new KSE and did everything it says to do in the README file, but after editing the save and putting back on my Xbox, it says game save is damaged...This may be a pretty dumb question, but do I need to mod my Xbox for it to work?

 

EDIT: Hey StormSinger im looking forword to your new saves FOR KOTOR II, I heard you were able to equip the rocket launcher on the Main PC? Thats awesome.

@Montross87 -- just wondering what you tried to edit... there are some limitations due to the fact that only 6 of the 7 sig files could be regenerated. PM me with details if you could.
