I did try to search around about it, and most results are kind of old and most answers say that it is already enabled. (even saw one that mentioned disabling it to improve performance in some games.)
I was checking out the Salsa Slide and SS21 ROMs and noticed that in Data there is a JIT folder. I was wondering, what is the purpose of this? I do know a little about JIT, my question is based around my understanding that it is already built into GingerBread. If that is the case, why is it included here?
