It's very common for savestates to not work across versions. They're a snapshot of the state of the emulated machine, so any changes to that emulated machine can make the state no longer make sense.

In cases like this, what usually works is to downgrade the emulator to the previous version (retroarch backups when it updates), then save on the console medium, then upgrade again and load the save (not savestate). Not sure if in a emulation like fbneo that is about arcade that'll work though, so you might have to continue on the previous version the games you want to play then update when they're all done.
