syn-z released a private beta for download that has experimental save state support. The states are uncompressed; sometimes they will total 2MB or more of memory card space. The author also notes they probably won't be compatible with future version of the emulator since this is a BETA. syn-z has requested that the file not be mirrored and the page not be posted, but we felt like giving you this WIP update.
