Hi,
I'd like to know if it is possible, in case you haven't got source code, to open an .exe file or not. I particular, I'm interesting in drive simulator game for PC, like Grand Prix Legends ('67 F1, multiplayer online game), and I'd like to develop a "mod" for this game in which, for example, there is '75 or '80 physics engine. I don't know where is physics engine of the cars, but I saw other files of the game and I didn't find it, so I think it is in the .exe file.
I know that it's possible to change physics engine of the cars because other people developed '65 and '69 mod already.
Thanks,
Monia
