Yes retro is in bottom right but when you try to use it the software check the voltage (see to right) when connected to the car it will be approx 12.7v, it has to be over 13v to allow you to continue. It will state connect to battery charge but this doesn't work as its a cracked copy. You have to install the "changes.iso" for it to change the voltage to 14v in top right. then you can use the retro section.
