Need for Speed Undercover - hacks and hacking

Post by Sethioz »

actually its too crap game to hack it, but i did found out that money cannot be changed easily. I guess this is why game engine sucks so badly and lags shit out of pc, because they tried to make some retarded way so it cannot be hacked, but it still can be hacked LOL.
i really couldn't bother to even find the money, what i did is:
i simply changed car price to 0, bought it, and sold it :) freezed car's price on 0 and did buy - sell few times. im sure that there's lot of things that can be done:
turboboost
speedboost
infinite nos
unlock stuff
but i really can't bother with it. included the screen too. that car was most expensive in tier 3, so i used that. you can simply search for the cost in memory editor "150000" on 4 bytes will do. it will find 4-9 addresses, but it should be 2nd address from end.

if anybody needs help with hacking NFS:Undercover, then reply here and ill give you some hints and tips on how to find stuff. you can also read the general topic about game hacking.


LATEST HACKS:
1. car cost 0
2. editing money (infinite)
3. Infinite NOS

1. car cost 0
-if new car costs 150000, then search 150000 in Tsearch (or any other memory editor). use 4bytes search.
-you will probably end up with 3-30 addresses, car's value is one of the last values usually.
-i changed Chevelle SS value. 150000 and i came up with 7-9 addresses and my right address was 2nd from behind.
-once you find one car's value, then you can EASILY look for the address range it is located in and make filter.
-for example my address was in range from 21000000 to 2FFFFFFF. in that range i had only one 150000.

2. editing money
-simple as that. you search for the money value on 3bytes (Tsearch, cheat engine..etc CAN NOT use 3bytes search)
-use ArtMoney to use 3bytes search. (it has to be 3bytes, not 2 or 4)

3. Infinite NOS
128 = full tank (1 byte search, IMPORTANT!!!)
0 = empty tank

1065353216 - full (4 bytes)

fucking hell ! i have no idea wtf is wrong with this dumb game...if 1 byte doesnt work, then try 4 byte value. once i found it on 1 byte with 128 and then i didnt. one of them works anyways. breakpoint can be found same way for both.

you will end up with at least 3 addresses, freeze them one by one to find right one.
now add that address into autohack, you have to only nop the first function.
huh ?
once you have added it into autohack, then 2 breakpoints appear AFTER you have used nitro and 2 more breakpoints appear AFTER nitro starts to regenerate again.
now add new address into cheatlist, it will be the FIRST breakpoint that appeared. to me its (6D7AE9) on 1byte.
in cheat list change value from 17 to 90.
now your nitro still generates, but does not decrease !

UPDATE:
sry about the money, it CAN be changed and it is what it says. what is very odd, is that game allocetes only 3 bytes for money, but Tsearch has no 3bytes search lol. Value is "R. Integer 3bytes". as far as i know only ArtMoney can search 3 bytes. this is how i found it. also it means that maximum amount of money you can have is 16777215, which isnt so much. thats why other games use 4bytes. on 4bytes you can store 4294967295, which is a lot more.

as about other things, there is discussion about NFS UC in pc games, not discussin gameplay or others here.

1. why you even need to change your money if its already so much ?
2. i think you are mislooking something or mistyped something, because as i explained, money is 3 byte value, your value is 4 bytes, game can not hold more than 3 bytes for money.

3 bytes = FF FF FF = 16777215
4 bytes = FF FF FF FF = 4294967295

learn how memory works. it is impossible for game to hold more than 16777215 money, because 4th byte after money is allocated for something else and if gets overwritten then it means some other function in game gets overwritten. and it probably will cause crash when game needs to use that function.

and Tsearch can not search for 3 bytes, however ArtMoney should find it easily on ALL.

wtf are you doing ? your computer's harddrive is not online dude, C:/ < this means the file is in your computer, not on the web.
use forum's "upload attachment' box !

once again why do you even need to change money if its already nearly infinite ? for that money you can buy and upgrade every car for like 100 times.

i do not know, maybe you have different version and/or edition of the game. the version i had allocated only 3 bytes for money.
use ArtMoney, put search type on "ALL"

well only explaination i can find right now is that game probably uses 2 or more addresses when money goes over 3 bytes .. or as mentioned before, your version and/or edition of game is different.

1. try artmoney on search type ALL and see how many it finds
2. start new game
- find your money (like described above on 3 bytes)
- now go to that memory position in Tsearch's "memory view"
- check if there is free bytes after the money, it would look like this if there is:

Code: Select all

49 F3 B6 00 43 43 FB ....
where "49 F3 B6" is your money and "00" is free byte.
and where 49 is the 3 or 4 byte address you found

if there is not, then it would look like this:

Code: Select all

49 F3 B6 85 43 43 FB ....
NOTE that this is only example.
- change it to "FF FF FF" (change 49 F3 B6)
- now confirm that money changed to "16777215"
- now sell something and refresh the "memory view" in Tsearch to see what happend, if there was free byte after, then you can easily change money to bigger values, but if there was no free byte, then i would like to know what happend too.

ok based on that, im guessing that game either uses 2 3byte addresses to store money OR game just overwrites the 4th byte, by overwriting something else. you did say that game crashed right ?
however what i don't understand is that if game overwrote the 4th byte, then how did it read it as money, it should not read it, because next address (byte) is for something else and game reads it as something else.
I guess its the first option, that game uses 2 3byte addresses for money. OR you have different version.

anyways as i mentioned, even cheathappens ppl couldn't make money hack into the trainer, which actually shows that they are quite amateurs if they can't find 3byte value.

Maybe they use the 1st 3 bytes for the cash, and the 4th one for the multiplyer, because then you could have FF FF FF * FF which 4.278.189.825 cash.
See how high you can go before the game crashes or your money fucks up

NFS undercover sure is something wierd, something i haven't seen before. like the nitro, when i found the breakpoint, then the "tmk" button in tsearch showed 4 bytes i think, but i only had to "nop" first 2, or something like that.

as usual i don't have that game anymore, if anyone else tries, then let us know.
