Fixing Mastering Level Show

[[RCZ]ShadowKing]

Using this guide you can "fix" master level in all season3 episode 1/2 or season4 mains.

1.Open you main with OllyDBG

2.Search for string : "----------" without "".Write exactly 10 characters like i did in "".

3.Double click on it and will appear the ASM code with what we need.

blablablabla...

now we need to understand something : main have 2 ways to show the level : using level number or using Master word.To know what way to use main check the master status in a call than if get what need jmp to second way.If the main will dont check the status and will dont get the jmp to second way than he will have only to show level number.So to "fix" this bug we just need to fill with NOP the CALL and JMP used for show master.

4.NOPing the commands(selected lines represent how code will look after NOP the CALL and JMP.

5.Save the file and run it.

I dont explained for all that open for first time olly because i dont have time to do it(i`m very hurry now...) but if you know to open,search,fill with nops and save you will can do the "fix".

I put word fix and bug in "" because a lot of ppl do this confusion.This is not a bug,is way MuOnline was built.

1. How add yellow line?
2. What's "nop" and how add?

Re: [Guide] Fixing Mastering Level Show

yellow lines represent the functions structure and the NOP is something like jump over these lines.I mean where line contain NOP the program will jump/skip these lines.To add nop click on code line,right click on it,Binary,Fill with NOP`s and thats all,than save and you fixed this ****.

NOP its not that program its going to jump, NOP have no real use and dont affect any flag.

90 Hex code, its for just what it say its name, NOP other opcodes, but olly and any program of course execute the NOP.

Just for make your definition more clear xD thx

Re: [Guide] Fixing Mastering Level Show

thanks for this very useful guide.


TagonZioM ,
it's very easy
make sure to backup your original main first.

1. open main.exe
2. right click -> Search for -> all referendces text strings
3. right click -> search for text ( enter ---------- , CTR+L until you got the right one)
4. double click the line
5. select the first red line:
006D4FC1 |. 68 60588500 push 00855860 ; /Arg2 = 00855860 ASCII "----------"
006D4FC6 |. 8D85 7CFFFFFF lea eax, dword ptr [ebp-84] ; |
006D4FCC |. 50 push eax ; |Arg1
006D4FCD E8 8ED3DDFF call 004B2360 ; \Main_ori.004B2360
006D4FD2 |. 83C4 08 add esp, 8
006D4FD5 EB 5E jmp short 006D5035
6. right click -> binary -> fill with nops
7.do the same with the 2nd red line
8. right click -> copy to executable -> selection
9. right click -> save file
10. select your destination and save.

if you still cant fix it i don't know xD
