Changing Loading Text

[Boop]

Wow, you are lazier than I am. I hope you're happy, you made me waste 30 minutes of my life...

ASM-Code: 00424403 . 8B4C24 1C MOV ECX,DWORD PTR SS:[ESP+1C] 00424407 . 8B15 08564500 MOV EDX,DWORD PTR DS:[455608] 0042440D . 68 FFFFFF00 PUSH 0FFFFFF 00424412 . 68 0D1B6000 PUSH lf2_load.00601B0D 00424417 . 51 PUSH ECX 00424418 . 52 PUSH EDX 00424419 . EB 16 JMP SHORT lf2_load.00424431 0042441B > 8B4424 1C MOV EAX,DWORD PTR SS:[ESP+1C] 0042441F . 8B0D 08564500 MOV ECX,DWORD PTR DS:[455608] 00424425 . 68 B4B4FF00 PUSH 0FFB4B4 0042442A 68 0D1B6000 PUSH lf2_load.00601B0D 0042442F . 50 PUSH EAX 00424430 . 51 PUSH ECX 00424431 > E8 5ACEFDFF CALL lf2_load.00401290 ; RAWR THIS IS THE ONE

That is the load thing that deals with the loading text.

WTF? That's not even a 'LEA' command! And for your information, Silva, I spent over seven hours trying to find that command (so I'm not that lazy ). I guess this proves that knowledge is power .

Anyways, problem solved.

Thanks Silva...

I think in this case, lack of knowledge is power . You thought about it logically, I just went through them one by one (although I did skip ones which were obviously incorrect ).

Ok, so the code for the loading text is found (finally!). However, how do I change the text to what I want? The 'MOV EAX' command that's supposed to point to the text in 'data.txt' freezes up when I try to make it read from a location at the bottom of the program. How do I change the loading text? Sorry for the short post.

I'm guessing you are trying to do something like this:

ASM-Code: 0042441B 36:A1 E09F4500 MOV EAX,DWORD PTR SS:[459FE0] 00424421 90 NOP 00424422 90 NOP 00424423 90 NOP 00424424 90 NOP 00424425 . 68 B4B4FF00 PUSH 0FFB4B4

Look at all the nops. You're new function is to long, so it starts over writing the next one (MOV ECX,DWORD PTR DS:[455608] disappeared).

You'll probably have to jump to a new location, then do

MOV EAX,DWORD PTR SS:[459FE0] ; eax holds your text
MOV ECX,DWORD PTR DS:[455608] ; ecx holds a magical number, this line gets over written.
jmp 00424425 ; jumps back

BTW, if you look at the code, you should be able to notice how there are 3 possible thingies (lack of a better word).

ASM-Code: 004243E4 . 8B5424 1C MOV EDX,DWORD PTR SS:[ESP+1C] ; start of 1 004243E8 . A1 08564500 MOV EAX,DWORD PTR DS:[455608] 004243ED . 68 6464FF00 PUSH 0FF6464 004243F2 . 68 0D1B6000 PUSH lf2_load.00601B0D 004243F7 . 52 PUSH EDX 004243F8 . 50 PUSH EAX 004243F9 . EB 36 JMP SHORT lf2_load.00424431 ; end of 1 004243FB > 83C2 FB ADD EDX,-5 004243FE . 83FA 02 CMP EDX,2 00424401 . 77 18 JA SHORT lf2_load.0042441B 00424403 . 8B4C24 1C MOV ECX,DWORD PTR SS:[ESP+1C] ; start of 2 00424407 . 8B15 08564500 MOV EDX,DWORD PTR DS:[455608] 0042440D . 68 FFFFFF00 PUSH 0FFFFFF 00424412 . 68 0D1B6000 PUSH lf2_load.00601B0D 00424417 . 51 PUSH ECX 00424418 . 52 PUSH EDX 00424419 . EB 16 JMP SHORT lf2_load.00424431 ; end of 2 0042441B 8B4424 1C MOV EAX,DWORD PTR SS:[ESP+1C] ; start of 3 0042441F 8B0D 08564500 MOV ECX,DWORD PTR DS:[455608] 00424425 . 68 B4B4FF00 PUSH 0FFB4B4 0042442A 68 0D1B6000 PUSH lf2_load.00601B0D 0042442F . 50 PUSH EAX 00424430 . 51 PUSH ECX 00424431 > E8 5ACEFDFF CALL lf2_load.00401290 ; end of 3

You're going to have to modify all 3 of them :p.

I still can't change the loading text. The program jumps down successfully and the nothing freezes, but the text I want to appear doesn't show. I replaced the original:

004243E4 . 8B5424 1C MOV EDX,DWORD PTR SS:[ESP+1C]
004243E8 . A1 08564500 MOV EAX,DWORD PTR DS:[455608]

with

JMP ######

and on the linked offset I inputted:

MOV EAX,DWORD PTR SS:[######]
MOV ECX,DWORD PTR DS:[######]

and then I inputted the text I wanted to display on the linked offset.

However, nothing appeared. The 'text' area was simply left blank. Did I do something wrong? I included a copy of the program on this post.

Please Respond

That was probably my fault... Didn't put lots of thought into it when I posted .

fixed:

  LF2TEXT fixed.zip (Size: 1.2 MB / Downloads: 197)

Explination:
doing :

Code:

MOV EAX,DWORD PTR SS:[######]

It uses ###### as a pointer, then moves the value at the pointer into eax.

So if ###### had the value of 7774823, then it would go to address 7774823, find what is stored there and move it into EAX.
That's not what we need.

Edit: It checks the value of the pointer and moves it into eax. So if ###### had a value of 777482 then it would move 777482 into eax, not ###### . Therfore when it pushes EAX, it pushes 777482 (which is most likely an empty location).

Code:

LEA EAX,DWORD PTR SS:[######]

That makes EAX point to ###### (basically moves ##### into EAX), so when it pushes EAX, it pushes ###### and it is all good.

Sorry if my explanation sucks, I learned by experimenting and what not, not from reading books etc, so my definitions of stuff are quite poor .

[1477]

Thanks for the explanation, Silva . Link for problematic EXE/program is now removed. Topic/Problem finally solved (for real) after almost a year of useless contemplation . I guess that in the end knowledge is power...

Sorry for the short post.

Thanks, Case Closed...

You could spend the entire code with
because I already have an exe and I only code

Thanks
