[Help] Game function searching - lua engine pointers.

Hello Unknowncheaters!

I'm programming on a small project for Mafia II. I know, this game has got 5 years but it's awesome; and mafia II has an lua engine.



I have found a lua-injector source code, and it is just working fine. Now I have a problem with finding more lua-related functions. Currently I have only a little experience in reversing some games memory.. and that's why i writing this topic. Returning to the subject; currently i've got this functions from mafias lua-engine:

• lua_pcall


• lua_tolstring


• lua_pushcclosure


• lua_setfield


• lua_gettop


• luaL_loadbuffer


• lua_tointeger

Now I want to reverse the games memory to find a function called lua_pushlstring, but how to begin?



Opening a function in CE and it looks like that:

Each lua function begins likethis:

Code:

---

push ebp

---

Code:

---

mov ebp,esp

---

Lua functions endings are similar too (scrolling through the memory, some functions have not a ret opcode):

Code:

---

pop ebp

---

Code:

---

ret

---

It seems to be there a lot of something looking like functions in memory but how I determine what parameters it needs or what is the return value or type?



The function I searching is adding something on the LUA stack, but what if the function will be luaL_loadfilex? Is there any chance to get the (BYTE*) pattern to find those two functions?




Thanks in advance.

Tomi20.



PS. And I Wish everyone here a nice day.
