We just need to figure out how people display messages through the libretro API, I thought returning false from retro_unserialize would be sufficient, but it doesn't appear that is the case.

This is not a critical bug, if the savestate is invalid, we still catch it in our serialization code and do not tamper with the system state until we know its safe. It just might be confusing from a players perspective because they will click load and nothing will happen.
