Hi can anyone explain what these settings do?
1.) force mono core
2.) boost mode
3.) Auto save
4.) dynamic Interpreter
5.)Fast boot

also is fpse developer going to optimize this for s3 to use all 4 cores??

1) as the name says, it will force to use only one core
2) can give a boost on some devices and/or some games. I never use it as I don't see a difference on my device
3) It will save yhe game automatically when you quit fpse
4) Can help some games to be compatible, but it's slower, so don't use it with games that work
5) It allows to skip the "bios" page of the PSX, you know, when you start a PSX, you have first the sony logo, etc. With fast boot, you directly go to the game.

i900frenchaddict - thank you, I didn't realize that's what fast boot mode did. now I can get in to accessing the memory card via the eject and restart trick.

Anthony (and frenchaddict) - what app do you use to verify how many cores are running? And, how do you know if they're being used specifically by fpse (vs being used by another app / system processes)?

On my One-X, I use Tegrastats to display cores activity.

But I don't know exactly the part of Fpse Vs other apps in the background. Maybe other apps exist which create a log of cores activity and displays what app uses the cores.
