I'm working on some texture mods for Twisted Metal 2 for PC. I can replace textures just fine but when I increase the size of the textures then the game will crash due to not enough memory being allocated. I can get around this easily with Cheat Engine by running the allocate memory tool and changing the pointer that points to the texture address to the address of the newly allocated memory. Then I can make the textures as big as I want without the game crashing.
But I would like to modify the executable file so it will allocate more memory and change the texture address pointer so I don't have to boot Cheat Engine every time I start the game. I looked around the exe with OllyDbg and Ida and found only one call to GlobalAlloc. I tried increasing the memory allocation size but I couldn't get it to allocate more memory. My experience with assembly is very limited so I'm not sure what to do.
Do you guys have any ideas? I just need to have the executable file allocate more memory and change a pointer to the newly allocated memory.
