Locate the call to sleep api in conquer and change the je/jnz(cant remember which one) to a JMP

sorry i dont understand alot of programming :/ but i found alot of call when i open "conquer" with ollydbg...

what is this call to sleep?

EDITED
i learned how to use the olly but.. i dont know what i have to find.. this call to sleep api..

nvm i found sleep and but i was already jmp look:

Code:

004BA554   . FF15 A8E06000  CALL DWORD PTR DS:[<&KERNEL32.Sleep>]    ; \Sleep
004BA55A     EB 19          JMP SHORT Conquer.004BA575
004BA55C     A3 E00C6900    MOV DWORD PTR DS:[690CE0],EAX

and now? this is the conquer exe can u edit to me? if not just help and i do it myself ^^ thank you anyway

My bad, its a JNB, in your case JNB SHORT 004BA55C, look up a tad further and change it to JMP

So

Code:

004BA54C    . /73 0E             JNB SHORT Conquer.004BA55C <----JMP ME
004BA54E    . |2BC8              SUB ECX,EAX
004BA550    . |83C1 19           ADD ECX,19
004BA553    . |51                PUSH ECX                                        ; /Timeout = 1245104. ms
004BA554    . |FF15 A8E06000     CALL DWORD PTR DS:[<&KERNEL32.Sleep>]           ; \Sleep

This will stop the CPU sleeping between frames and make it give 100pct to Conquer. Once you learn a little more you can play with the above code to limit frames to something custom 50/60 is good, your eyes wont notice anything above so it would just be overkill getting 100 frames.

Lower this number to change the limit on FPS. I forgot what number is good.. play around with it. Post not directed @ M obviously.

Thank you, M it works now

Hey, I tried the way you described I was able to find JNP and stuff but I couldn't find the ADD,ECX 19 or any other codes like it around, but the kernal.sleep was there and 7 codes above it was the JNP, did they change it in the latest client or something?
