I already know how to use the tools to softmod. But where can I learn about how the game exploits are used to softmod, from a technical point of view? Like with Splinter Cell, you load up a bad save, there's a buffer overrun somewhere, jumps to some arbitrary code that XXXX? I assume the exploit code installs a new dashboard and everything, but doesn't Xbox also do a signature check to make sure that the code is signed before allowing it to run?
