Hello, im trying to mod Forza 4 - Engine Swaps, i looked up this tutorial http://www.xpgamesaves.com/topic/29429-tut-how-to-add-any-engine-to-any-car-on-forza-4/#.UORrqm_aWaU i says that "you need RGH/JTAG to add custom entries unless you overwrite existing upgrades". How does an Xk3y count? according to http://x360key.com/features (the official site of Xk3y) is says "FPGA fully updatable from USB media via built-in, in-system JTAG programming" does that mean that i can mod Forza like it is a Jtagged Xbox, because i use Xk3y? or do i have to overwrite old entries, like it says in the tutorial?
JTAG programming is not Xbox specific. Jtag programming stands for Joint Test Action Group, which is the common name for Standard Test Access Port and Boundary-Scan Architecture. Jtag ports are used for debugging PCBs with the boundary scan method, which basically allows you to watch voltage, pin states, etc. So the xK3y does not "jtag your system", but it basically emulates your dvd drive. AFAICT you can iso mod any game and use it on an xkey. TL;DR No because RGH/JTAGs allow unsigned code, and the xkey is only a dvd emulator.
As Crackbomber said, It's only a DVD emulator, it doesn run unsigned code therefor it's not the equivalent of a JTAG or RGH.
Allright, one last question then.... as far as i can read, you need JTAG/RGH to mod the Forza 4 file, where you add extra engines to one car (so it is swapable) but you can easily "replace" one of the origninal swapable engines - how can i be that some cars have like 287000 and up to 287003(3 engine swaps) and if i find a car with 27800 to 27801, that i can not make a 27802 my self, how does it know the diffence between replacing a old engine swap, and just adding a new? Edit: i saw this video: http://www.youtube.com/watch?feature=player_embedded&v=73zjDzEMVoo there he only flashed the drive, but have a lot of engines, so how did he do it compared to the first tutorial?
