make folder data in your game folder.
make folder SAVEGAME in data folder
make folder SLOT00 in SAVEGAME
copy fallout 2 save.dat to SLOT00 folder.

this DLL if injected, takes one key press of ctrl-right. your game will crash. go and refresh view of SLOT00 folder contents.

your save.dat will be 0kb. all data will have been cleared but nothing written. the crash is because of complication with strncopy.

the ultimate solution for no crash no doubt, a few instructions modified/added. but for now you have insight.

Code: Select all

#include <Windows>

void SimpleGoto&#40;&#41;;

HRESULT WINAPI InputThread&#40;LPVOID&#41;;

BOOL WINAPI DllMain&#40;HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved&#41;
&#123;
	if&#40;fdwReason == DLL_PROCESS_ATTACH&#41;&#123;

		DisableThreadLibraryCalls&#40;hinstDLL&#41;;

		CreateThread&#40;NULL, 0, &#40;LPTHREAD_START_ROUTINE&#41;InputThread, NULL, NULL, NULL&#41;;
		return TRUE;
	&#125;

	return FALSE;

&#125;

HRESULT WINAPI InputThread&#40;LPVOID Param&#41;
&#123;
	while&#40;1&#41;&#123;
		Sleep&#40;1&#41;;
		if&#40;GetAsyncKeyState&#40;VK_RCONTROL&#41; & 0x8000&#41;&#123;

			SimpleGoto&#40;&#41;;

			Sleep&#40;1&#41;;
		&#125;
		if&#40;GetAsyncKeyState&#40;VK_PAUSE&#41; & 0x8000&#41;&#123;

			break;
		&#125;
	&#125;

	return TRUE;
&#125;


char szSaveBuff &#91;30051&#93;=&#123;0&#125;; // modding wiki . decimal value for header size is 30051.
void SimpleGoto&#40;&#41;
&#123;
	// with a debugger changing the register eax from 0xcd2a20bc to offset of szSaveBuff
	// gets a bit further, but still confused.

	DWORD dwSaveAddr = 0x00452488;
	__asm &#123;
		call dwSaveAddr
	&#125;

He's either genuinely schizo or this is the worst attempt at lying ever.

the worst liars being more convincing. Don't talk about genuine when your own skills are in jeopardy.

My skill at being schizophrenic is in jeopardy? That's a good thing, I'd hope.

I asked a damn legit question you moron and you still throw bullshit. And I don't even know what the hell you're talking about in the second sentence.
Baa what's the use, it's becoming clear that suicide is probably the only feasible option for this kid.

I will be merciful.

What Cakester was working on was first the flow of the save/load process. Upon pressing the red button you are prompted with NOPE YOU CANT. but with some inspection he found the non-demo's normal save routine was still present.

the source code in his OP compiles into a DLL. to test for an effect, once you inject it, you go and press the save game button.

the result is a save file is overwritten if present, otherwise a new one is created. it will be blank.
