I got so confused. I was remebering all wrong, I thought about MK9 trainer.. and when I found the actual Injustice trainer in one of my disc.. it had just Inf. Health and Inf Energy..
so I went around and dig here and there.. and found the perfect one! thanks LinGon, the god of perfect game trainers!
found it on this site, the mediafire link.. in case you wanna download it from there..
http://flingtrainers.com/injustice-gods ... -8-lingon/after all those little adds help the guys that keep the trainers well organized

and if by any chance the links don't work for you I'll leave a backup here

(I couldn't upload the trainer right here, so I will make a post to upload the trainer)
