In DMC4 is there anyway to make enemies tougher? because i m too bored of enemies die in a few seconds. i found the shared code controlls health of enemy and player

[vergilganesh]

I tried using addss xmm0,xmm0. but every time health is doubled so there is increaing. i can do it in the principle of counter . but how to do with this CE?

[eax.qbyte]

Find out what accesses your enemies health. It should show you some lines. Ignore them all.
With the break-point(find out ...) running go in game and shoot a single bullet to the enemy.
It will add some instructions which have run for a few times.
Those are where you should search around for the value that subtracts from an enemy's current health when you hit them. Then you can change that value ex. divide it by 2.
Using code injection that should be easily possible.

but accessed instructions are scalar instructions. there is one subss ins but whic is never accessed. see the picture that shows what i got

[eax.qbyte]

Picture sent by you contains good information.
What I get from it is:
- ESI+18 is your enemy's current health
- ESI+28 is a factor that amplifies the damage taken to that enemy
- EAX+14 is the damage your gun is trying to deal that enemy.
and may be that subss instruction never accesses the health address directly but it subtracts the value received from esi+18 in this op-code movss xmm0,[esi+18] and stores the result in xmm0 then after it, the result value is returned back to [esi+18] in this op-code movss [esi+18],xmm0.
So... at exactly that selected op-code in the picture you have no problem to inject a code to divide the value of xmm1(the dealth dmg that will be subtracted from xmm0) by 2 or 3 or whatever.

"there is one subss ins but whic is never accessed"
What eax.qbyte said.

Btw. I found better "super speed" (check other topic)

X axis is accessed by "addss xmm1,[edi+30]"
and Y is accessed by "movss xmm1,[edi+38]"

After analyzing, we can see there are those calculations performed:
newX := Xd * XdMultiplier + oldX
newY := Yd * YdMultiplier + oldY

[vergilganesh]

Analyzing set of instructions is essential in advanced cheating. got it. Special thanks to mgr.inz.player & eaz.qbyte. Thank u buddies.

i want to know abt floating points. If the codes accessing addresses are

[_Veggy]

The only difference between what you posted and what mr ing player posted are the stacks being used.
mr ing player uses the system stack (esp) :

push (float)2.0 //push floating point value 40200000 (hex) on the stack
divss xmm1, [esp] //Divide xmm1 reg with 40200000 (divide by 2)
add esp,4 //balance the stack, so we get back to Original stack
before we applied the code

Your code vergilganesh uses the floating point stack.

fld dword ptr [memadds] //push floating point on stack
fsub dword ptr [another] //substract
fstp dword ptr [memadds] //pop back result from stack

Not sure what you exactly want, but both things are doing the same thing.

About your question giving them a higher health.
I would stick your code on a flag like this:

cmp [HealthFlag],01h
je > ..
mov [HealthFlag],00h
mov [HealthAddress], <high value>

etc..

Basicly the above code enables the code ones, than disables the code.
Although you might not have all the enemies at a higher health because it
disables so fast.
In that case I would go for a mouse routine function, hover mouse over enemy, increase health, than fight him like usual.

[vergilganesh]

If it is fadd instruction is no prblm.
because add ins is like below.

fld dword ptr [pointer]
fadd dword ptr [pointer2]
fstp dword ptr [pointer2]

just multiply with 0.5 or below after the load instruction then the code will be done.
but for the sub instruction this is not actually works. Bcoz fsub ins load floating point of full health at beginning. Hope u understand my prblm

[eax.qbyte]

[vergilganesh]

I want to make enemies tougher.. I can do it from these codes

[eax.qbyte]

Ok. If we assume the value stored in [eax+0c] is the dealt damage to the enemy then I think this code does what we want.

[vergilganesh]

I think i found a better route.
