Dead Space 2 [DS2] - hacks and hacking

[Sethioz]

If you do not know how to hack games on basic level, then you must first read the following guides
> Knowledge Database article of Basic Game Hacking
> Guide and Discussion about basic game hacking


>>> Video demonstration of unlimited ammo
>>> Video demonstration of weapon upgrades


1. Unlimited Ammo with reload (credits)

>>> see Unlimited Ammo Hack article in my wiki to learn this in detail

- search for amount of ammo shown in inventory
- if you have 20 in one stack (that small number shown on stack's icon, not the stack size, then search 20 on 4 bytes
- do the necessary filtering and find the address (again if you do not know how, look at top of the post !!!)
- you should end up with 2-3 addresses
- find the one that changes ammo
- now easywrite script can be written based on that (see the wiki article mentioned above)

- credits, this isnt really a hack. enable the easywrite script to prevent ammo from decreasing and start selling your ammo. you'll get money, but ammo will remain, so you can sell it as many times as you want. However if you want money, just change it the same way you changed ammo (not tested, but will work)


2. Weapon Upgrades - this is one of my famous hacks that allows you to upgrade weapons beyond their capabilites

First i have to say, it is very tricky ! i have never seen anything like this before. DS1 was similiar, but i never went that far in there.
so lets start, why its weird, is that it uses float and byte value types for weapon upgrades. for example pulse rifle's reload speed is in float, but capacity is in bytes. also in memory, mapping does not seem to make any sense to me, but here i will list how to find.

NOTE - artmoney and tsearch does not seem to be working so well, use cheat engine for float values

> Linegun
- width - float, search for what it is. 1, 1.5 and 2
- alt fire - float. search what it it says. this will make the mine either explode fast or slow

> Pulse Rifle
- reload speed - float - search what it is. for example to me it shows 1.200000048, but search 1.2 using CE
- capacity - 4 bytes - search what it is.
you can also use the calculation. once you find capacity, then they are 12 bytes seperate. here are examples
reload speed is 17EF9170, then capacity will be 17EF9164. do not forget, that this is HEX.
do the following on your calculator:

Code: Select all

17EF9170 - 17EF9164 = C

C in hex means 12.

what about item hack? like med pack hack? to have 99 med pack in one item slot

[Sethioz]

i havent tried, but it should work the same way as everything else. why dont you just find breakpoint for medpacks and NOP it, the basic process that has been described in Basic Game Hacking article on knowledge database (linked in first post).

[mintiandco]

i tried to do it the same way as how i did it for resident evil 4 and 5. I used the ammunition and then i tried to find the item hex id but i cant. How am i supposed to find the med pack amount if its not numerical or stacked. I tried using 1 and 0 value when i store and take out my item from the store but its still useless.

[KEN]

I never saw this game but i will try to explain u.U say "to have 99 med pack in one item slot"
Does it mean game allows only 1 med pack in 1 slot?Slot is like in resident evil 5?
If u can see how many number of med pack u hav then u need to read this one: http://sethioz.com/mediawiki/index.php5 ... _Ammo_Hack

However if values are unknown or not in numbers then read this guide: http://sethioz.com/mediawiki/index.php5 ... own_Values

These tutorial are explained with tsearch but as i see sethioz said tsearch is not working so u can use cheat engine and do the same with it.

[Sethioz]

dont think that 1 and 0 works in this case. 1 and 0 is more for things that are on / off or "is" and "is not". medpack is probably considered as item.
i have no interest in DS2 anymore, but what i can suggest. is first do the weapon hack. just follow my tutorial, then start to play around with the values in HEX. go to that weapon location, where are stored all tuning slots ..etc. try finding the actual item / weapon ID.

in other words, like i did it in RE4 and RE5. once you find item slot, you can change it into medpack and change the amount to 9999 or whatever you want.

i might be wrong, but im very sure that if you make infinite ammo, you will also have infinite items, that includes medpacks.
so if all you are after is unlimited medpacks in one slot, simply make unlimited ammo hack and there you go.
you have to breakpoint the ammo and then NOP the function.
this works, because game uses same function for ammo and items. you can even sell items, they still wont disappear.

[mintiandco]

no success. i found the statis address but its different from RE4, this one seem more complex. In resident evil 4 it is easier to identify which one is the item id.

it seems the item id is made up of lots of byte?

[Sethioz]

yes it might be something longer. if you really want it. .. get only 2 things in inventory.
1 weapon and 1 medpack.
do unknown value, then change medpack to something else, like some item and do changed ...etc
im sure you got the point.

once again, if you're just after unlimited packs, use unlimited ammo hack. you'll get unlimited inventory items (everything is unlimited).
if you are advanced user, you can use olly to track medpack back from the breakpoint. for example if you NOP the function that decreases ALL items, you can trace it back to individual items, lets say like medpack. however ive never done this, so cant help.

Tsearch might work. find ammo, breakpoint it, then in disassembler window, register and check the register values. complicated, i know.
look aliens vs predator 2 hacks, ive done something similar there with Tsearch. i found source addresses for ammo. address where the original value comes from.

[mintiandco]

i still cant hack this game >:(

hmm...

[Sethioz]

what you mean under "i cant hack" ?
does it mean you couldnt do this specific hack or nothing at all ? as i said, items work fine when you NOP out the ammo function / instruction.
