Setting up a 3in1 EZFlash

I've had it for a week now and under M3 Sakura but i haven't figured how to exactly use it right. Supposedly under M3 Sakura 1.12+1 you can use your EZFlash in the UI of Sakura without Exploader but I have no idea how to set it up that way.
I've also noticed that both ram and rumble don't work, would this be a problem from Sakura's end or my configurations (tried on rumble enabled Star Fox)?
I can't save on my GBA games on Exploader, I have the ability to save but when I reboot and come back to it, its missing or either says the file is corrupted.
And Exploader can't read over 200 roms?

Thanks for the assistance!
