[MASM]Injector.

[Void]

This is the ugliest injector you'll ever see.

Try to prove me wrong.



Here's the code, fools.

I used macros this time 'cause I'm lazy..

[cosconub]

Not bad i like how it looks

i like alota ugly gui's but ppl hate em

[Void]

When I first assembled it and ran it, I almost cried.

[Auxilium]

Noice. No exceptions.

[.::SCHiM::.]

Wow that's nice man!!
I figure now it's my turn to go and release something tough

[TheCamels8]

I like ASM so much
It's awesome.
Also you chose the best game: "WarRock.exe"

[Void]

Wow that's nice man!!

I was hoping someone other than me would post code in this section.

Can't wait for your release of whatever it is you're working on.

[why06]

Hey I post code in this section.

Here:

Using System;
public class Program
{
static void Main()
{
Console.WriteLine("Hello C#");
}
}

[Void]

Hey I post code in this section.

Here:

Console.WriteLine("Hello C#");
}
}

yeah, sure you do. ):

Whoa. Thank you so much for posting this. I was always fascinated in low-level coding. I am, however, so confused about this memory management that you usually HAVE to use while coding in ASM. So, I have a couple of questions. Where did you start to accumulate such knowledge in memory management and Assembly? I would really love to start learning to develop low-level binaries so I can exploit hardware for piracy. ( PS3, iPhone ) Thank you so much for your time, Void!

Please organize into Code snippets, it's impossible to tell where it begins and ends. Thanks if you can.

Obviously random that don't know what happens/happened in this section.. /facepalm

You're right about me not knowing what happened, please explain. I'm not new to the forums however.

check his post and you will find in there [Highlight=ASM]
It was the old tags that this forum had.. for code.
So, thats why the code looks so messy now..

Oh ok, I'm still getting used to the new look and everything, thanks for telling me.
