Copy Function Beta [For PTC]

[topblast]

Well I just put this together is about 3 mins so it might got a few logical errors in it.


I DID NOT TEST THIS CODE.

But the way i wanted it to work is to Copy the whole function into a place in memory. Then return the addy to the space in memory, Stop like the bottom half of Some detours. So I Copy the whole function and you can use that function anytime you want to.

I have one that i am 100% that will work but i dont want to post it, it is built for profection :O

So in other words

1. CopyFunction(ENGINE_LTC_FOR_PTC);
2. Copy PTC Function into memory
3. Return the Address of that function and store into your Typedef function lets say
   PTC = CopyFunction(ENGINE_LTC_FOR_PTC);
4. PTC("ShowFPS 1");
5. and it SHOULD work

void* CopyFunction(DWORD addy)
{
	if (addy == NULL) return NULL;
	int len = 0;
	PBYTE func;
	DWORD dwProtect;
	LPVOID ret;
	func = PBYTE(addy);
	while(func[len] != 0xC3 || func[len] != 0xC2
		  || func[len] != 0xCA || func[len] != 0xCB)
	{
		len++;
	}
	ret =  VirtualAlloc(0, len, (MEM_COMMIT | MEM_RESERVE), PAGE_EXECUTE_READWRITE);
	if (ret != NULL && 
		VirtualProtect(LPVOID(addy), len, PAGE_EXECUTE_READWRITE, &dwProtect) == TRUE) return NULL;
	{
		memcpy(ret,LPVOID(addy),len);
		VirtualProtect(LPVOID(addy), len, dwProtect, &dwProtect);
		return ret;
	}
	ret = NULL;
	func = NULL;
	return NULL;
}

Nice Job..

[topblast]

I just saw that i have some unneeded code in they but it wont hurt i guess.

[speedforyou]

nice thanks

[fragbox]

good job...... i guess dont know what its for? but

[SNal2F]

cool its the same thing i was talking about in the other ptc post redirecting to a rewritten function :P

sure you was.

[SNal2F]

sure you was.

...........how isnt it when i redirect a pointer to my own function and rewrite it? Think about it logically

not the first time i have talked about it either , trust me this method is older then me & your birth age they did this shit in the 80's

lol, but this function is not complete. you see some asm functions have RETN at both sides of a Jump, I dont have the PTC in ASM so i wont be sure if this will work but it is worth a try..

Can someone give me the PTC function in ASM and i dont need to copy the Function, I will just convert it to usable code

Not sure since this is from the top of my head:

mov eax, ltc (ltc+208/whatever you call to call too shove comands)
push pCommand (has to be char*/PCHAR)
call eax
add esp, 4h

[SNal2F]

all ptc does is call a sub function

       __asm PUSH szCommand
                __asm PUSH 0x8003F0
                __asm CALL SubConsole
                __asm ADD ESP,8

You both have it wrong, i already know how to create a PTC SUB which calls the PTC function.

But what i want is the ASM code inside the PTC function.

PTC wrapper

you have it wrong...

that is the code inside the ptc @ 0x208 prior to checks

table -> call ptc ->call sub console

Then that'd be the console function not the push to console function.
Get your terms straight.

Anyway, I don't know what you try to achieve by copying the function to a different location (it's not like it will work...). But here it is (the first bit of it, if you want more you'll have to dump it yourself):

Note, copying this doesn't make any sense, for starters you'll have to re-write all offsets

Just so you know
