Pointer Search Development

[weltall]

-dump1-dump2, dump1-dump3, dump1-dump4, dump2-dump3, dump2-dump4, dump3-dump4 i hope i didn't miss anything plus each time we need to reload the files in one type of implementation and in the other one we need a lot of ram

Hi,

you are right. I forget the amount of ram that is needed to load all dumps at once.

Hmm... maybe i can write i script myself that does these steps.

Can you please tell me how i can identify a pointer in a dump like your pointer searcher ?

Bye

i could make a command line version so that you can manage the output

[Blaster99]

Hi,

that would be very nice.

thanks a lot

okay... i'm pretty confused about the pointers and stuff in the wiki... so i'm gonna make this simple... probably cause it's 5 am and i haven't slept yet.

this is my code:
_C1 Items
_L 0x80640240 0x01F40058
_L 0x00000031 0x00000000
_L 0x80640244 0x01F40058
_L 0x00000001 0x00000000
_L 0x8064024C 0x01F4002C
_L 0x10000001 0x00000001
_L 0x80640250 0x01F40058
_L 0x00000004 0x00000000

but, i want it to go to 640240 and first check if there is ALREADY some value there... if there is, don't change anything but increment the address until it DOESN'T find any value (other than 00)... then proceed with the code. as if that was the starting point. however, it WILL decrement the other counter (1F4 in this case) by however many times it had to skip.

again, lets keep it simple... say it had to skip once... so the code ends up like:

_C1 Items
_L 0x80640298 0x01F30058
_L 0x00000031 0x00000000
_L 0x8064029C 0x01F30058
_L 0x00000001 0x00000000
_L 0x806402A4 0x01F3002C
_L 0x10000001 0x00000001
_L 0x806402A8 0x01F30058
_L 0x00000004 0x00000000

i realize that it basically looks like it just skipped the first iteration, but you'll notice that in he 5th and 6th lines:

_L 0x806402A4 0x01F3002C
_L 0x10000001 0x00000001

didn't become

_L 0x806402A4 0x01F3002C
_L 0x10000002 0x00000001

as it would've if it was an actual iteration. of course, it also gets messy if you DO want it to change (in otherwords a "skip" in iteration as if the first one went through).

to give an idea of what i want to do... lets say i have 5 slots... and i want to add 5 swords (each level from 1 to 5)

if i didn't have any items it would come out like:
sword 1
sword 2
sword 3
sword 4
sword 5

but if i had say two shields (level 1 and 2), then it'll be:
shield 1
shield 2
sword 1
sword 2
sword 3

there's a whole other complication about if i had a sword 1 and i added the "five" swords, making sword [1, 1, 2, 3, 4]... but that's another issue i'll leave for later.

Hmm...I understand how to find pointers and make the codes, but I'm not quite sure what the codes "do." Can someone explain to me the ins and outs of pointer (DMA) codes?

[gangstamalu]

Well in some games the address changes every time you lets say you go to the next level or reset the game. It's sort of like a anti-cheat device. Pointer codes are codes that point to each code. So if you find the pointer code and offset(difference btw 2 codes) then you can use it to point to each code every time you go to the next level, etc.

Wow that still sounds confusing. Well let me try to show you an example.
Theres a game with levels.
Level 1
Address for Health
0x0000001
Your happy you found the code
Level 2
Address for Health
0x0000002
O No the address you found on level one doesn't work anymore.

Your choices are ether to go to every level and find the code for health on every level or use the pointer search to find the offset and point to every code from level 1 to level X.

[CanisLupus]

Well, I understand that much. xP I'm just a little confused about what the "base" is? Is it a useless address used to store the value you want?

[weltall]

no it's were the pointer is

[CanisLupus]

What exactly is the pointer? Sorry, the pointer searcher makes it really easy to find it and make the codes...I just don't quite understand how it works is all.

EDIT: Nevermind, I think I've figured it out now.
