so if I got my everdrive in november, what updates do I need?

[maikaregion]

do I just swap the one firmware update for my current ever drive file and I'm done? will it work with all of my saves? or do i need other updates too

also can someone explain to me the different save types and when to use which one/what they mean. force srom etc

thanks for the help, sorry im so retarded at everdrive :X

by the way i have no idea what i got the first time as I simply copy and pasted everything off of a friends everdrive
