The Saiyan Project is a sysdll written for the Xbox 360. This sysdll will exploit GTA V's script VM when the game is launched. Several hooks are installed in the games memory for several different purposes. Read the source if you're interested.
XeClutch - Hook to script VM, developer mode patch, ban bypass, and most other scripts/patches/hooks.
proditaki - Bypass for script.rpf checks, help with bypass for update.rpf checks bypass for vehicle creation, and the method used to spawn vehicles.
