SECOND HALF OF ADDRESS(+0880)
FIRST AND SECOND OF DATA
END

---

How your template should look when done.

Code:

---

lui t0 $08d1
sw t1 $44dc(t0)
ori t1 zero $0003
jr ra

---

Now On Ps2dis double Click your address " 09000000" and go to command and enter this

Code:

---

lui t0 $08d1

---

then click ok now keep doing this going down ps2dis and your template

Now Your Ps2dis should look like this

Code:

---

0x09000000 0x3c0808d1 //lui t0
0x09000004 0xad0944dc //sw t1
0x09000008 0x34090003 //ori t1  zero
0x0900000c 0x03e00008 //jr ra

---

Now here is your hook 0x00000098 0x0a400000 //Hook

now combined and this is wut you got

Code:

---

0x00000098 0x0a400000
0x09000000 0x3c0808d1
0x09000004 0xad0944dc
0x09000008 0x34090003
0x0900000c 0x03e00008

Tut By ImMoRtAl-

Great tutorial immortal, it's great help.

Np it all cause i love u guys =)

wow i think im starting to understand how to use it, thanks great guide

Np throw some rep my way then....

FAIL, this almost as shitty as Xx958xX's first sub "guide." This isn't teaching ANYTHING!

lui t0 $XXXX
Loads the first 16Bits of your address +0880 and shifts it left 16Bits. you add one here because store word must use the negative rule.

lui t1 $XXXX
Loads the first 16Bits of your on value and shifts it left 16Bits. you add one here because ADDIU (NOT ORI, thats for nubs unless you know how ori really works!) uses the negative rule.

ADDIU t1 t1 $XXXX
Adds the last 16Bits of your on value to t1 and stores the result into t1.
t1 = t1 + Last 16Bits of on value

sw t1 $XXXX(t0)
Stores the contents of t1 to the last 16Bits of the address, it also stores t1 to the first 16Bits trough (t0)

jr ra
Returns the addresses (and values) back to the games original values, turning are subroutine off

j $XXXXXXXX
Jumps to the start of are subroutine, this is your hook and it keeps the subroutine on because of the jr ra's turning it off

You do NOT need the Negative rule with or immediate. You probably don't even know what ori dose.

I don't mean to bash you so much but you need to explain what the hell is going on! In the PSP community it is hard to find any one who knows the BASICS!

Dude ShutThe Fuck up this is just for the begginers like who started today... so go put a bannanna up your ass and sux a cock

dont matter if u gunna teach teach the right way atleast u need to teach the 7fff rule / negative + you dont need to analyze for a simple sub routine, analyze would be for if you we looking for shit in ps2 dis... other wise its pretty much useless

~ DeToX

thanks for reminding me about that.....


sorry for the bump

idk i never use that template i use this one


lui t0 $[First Half Of Address + 1 If Second Half Is 8000 Or More]
lui t1 $[First half Of Value]
ori t1 t1 $[Second Half Of Value]
sw t1 $[Second Half Of Address](t0)
JR RA

and soem safe hooks that are good:
Safe HOOKS:
00000004
00000024
0000004C
00000098

idk but sometime when i do my sub they freeze. plz tell me what is wrong with this sub. i dont do to much sub b/c sometimes i do them wrong. plz tell me what is wrong in this sub i made and why does it freez in game.

#inf ammo
