with all due respect, you don't know fuck all about exploits do you? (not that i'm an expert)
first of all, that is a font exploit. the splinter cell exploit is only a means to installing the font exploit, the hack is not called the splinter cell exploit as you have been calling it.
second of all, you don't even need to do all of that what you have put in your tutorial, like copying the entire c drive from slayers. it is unnecessary.
third of all that exploit is out of date and i 'think' it is prone to clock loop. if it is then you shouldn't be writing tutorials because it just encourages people to use dangerous fonts which can harm their xbox.
i strongly suggest that you actually read about exploits and learn about them before you go around installing them on lots of people's xboxes.
