Some strange hacks may make a game or two run but it will make many other fail in very unexpected ways, which is hard to debug. For instance instead of crashing when a game uses some unimplemented method you could just return some hard coded (incorrect) data which may work for some games but it is now completely impossible to fix any other issues because everything is running in an undefined state. In short, it's a mess.
