What you will need:
1 - Ram Dump of a Game
2 - PS2DIS Download
3 - A USB Cable
4 - A Working Computer
5 - A Code Your Writing Into a Sub
6 - Some basic coding knoledge
------------------------------------------------------------
1 - Geting the Ram Dump
Open CoderPR in the game your subing and go to the options and click "Dump Ram In Slot 0?"
Once the memry stick light stops blinking quit and conect the USB cable
2 - Now open up PS2DIS and select the Ram Dump 0 under CoderPR>>ramdumps>>Dump 0
It will have a box that looks like this:
Quote:
Load From 00000000
Address From 00000000
Change the address from to 08800000 (Five zeroes after the 8s)
and hit ok, then after that you need to find a "Code Cave" that is just along line of zeroes, so press Ctrl + F and check the box that says "As Hex String" then hold zero in the long box for around 10 seconds and hit ok. You will see a bunch of things that say "nop" ok now you need your template:
Quote:
lui t0 $ [first half of address + 1 if second half is 8000 or more]
lui t1 $ [first half of hex]
ori t1 t1 $ [second half of hex]
sw t1 $ [second half of address (t0)]
jr ra
ok now take the top line in PS2DIS that says "nop" and enter lui t1 $ in-place of nop in the command area. No notice how it says [first half of address + 1 if second half is 8000 or more] you are going to enter the first half of the address,
Example:
Quote:
#Extreme Flash
;Jet.HacKer
0x0016ADC0 0x3C044153
Dont enter the "0x" at the front, the first half of the address is 0016, so you want to enter that into the command right after the $ symbol, If the second half of the Address is more than 8000 (Letters are MORE than 8000) then you will add 1 to the right side of the first part of the address. In this case the second part starts with a letter, A, that is higher than 8000 so the 0016 now becomes 0017.
Now the second line of the template is ori t1 t1 $ you will choose the next "nop" code (right below the one you just moddified) and add that then the first half of the hex, in this case its 3c04. So far so good, the third line is ori t1 t1 $[Second half of the hex] so enter the command and then enter the second part of the address, in this case it is 4153. Next is sw t1 $ [second half of address (t0)] so enter the command and the second half of the address, now notice how it has a "(t0)" at the end? that goes at the end of the line you just typed in,
Example:
sw t1 $ADC0(t0)
now to enter the jr ra, the simplest thing ever, just replace the next "nop" with jr ra lol
Now click on the lines of codes fom top to bottom of what you have edited and copy the address and data down to a notepad document, add "0x" to the begining of each address and data (hex)
3 - Geting the hook
There are three Universal (works for all games) hooks that i know of:
Quote:
08800024
08800098
0880004c
in PS2DIS press "G" and then enter one of the hooks, i use 08800098 mostly. then add a j $ to the command, the number you enter for this one is the number you copy and pasted from the first line of hex, the vid will explane more, after that copy the address of the j $ and paste it write above all the other lines, then copy and paste the data from j $ to the hex of the hook (top code) highlight the code you just made and press Ctrl + H and replace 0880 with 0000, theres your subroutine.
