Hi,
I wanted to know if it's possible to edit the Savegame, to get the weapons I would have got if I would have killed some major characters. Like Omen's Shotgun or Brayko's MPs.
I let both live so I didn't get their guns. But I have a save where I got them and now I want to edit my savegame to get the guns even if I spared them.

I found the weapon lines:
Omen's Shotgun:
4C4F41444F55545F574541504F4E5F35345F4163717569726564000000000100000015 LOADOUT_WEAPON_54_Acquired..........

Braykos MPs:
4C4F41444F55545F574541504F4E5F35355F41637175697265640000000001000000 LOADOUT_WEAPON_55_Acquired..........

But If I add them to my save, behind some other weapons like 53 or so I can load the game but on the loadingscreen I get a crash.

Can someone help me???
I really want the guns but I don't want to kill them. Any ideas?

you can not add to a save-game some code for some reasons:
1) It has check-sum (maximum and minimum file size + protection)
2) The save game holds a certain "sequence" that must be followed
so only the game can make this "sequence"
3) You can only edit values that are already exist, if you want to add stuff to the save without it crashing you must be an expert in cracking!

I had trouble hex edit money amount and knew there would be a check sum on the save game usually is, so i must have change too much - set money too high if it was a 16 bit value then a 24 bit value would probably crash the save game on load , a set number of 00 bits of padding between money value and next value.

I just wish I was good at such things , hash headers and check sums so I could make my own decomlilers/unpackers for games then .. etc

My knowledge is hex edit , and pointers , been able to tweak and create my own action replay codes for pokemon on the DS by studying other working codes and knowing memory value offsets and points ...

I am not asking for any help or someone to teach me .. and thats information is not usually given out anyway

Then study and when you learned enough try to make those stuff.
the stuff you want to make isn't as easy as finding offsets and values...

But I even tried replacing some other weapons like LOADOUT_WEAPON_45 par example but it still crashes.

Is there no way I can add the weapons or replace others with them without getting crashes?

I know that i need to study , just any advice sone something simple to study with ?

"I want to crawl before i walk and walk before i can run"

I think I can crawl almost with hex editing on a basic level.
