Third release for GSE.
This is a rather impromptu update against v0.2, fixing state previews not showing if a ROM was loaded (and fixing a crash due to trying to show a state preview without a ROM loaded).
Several download options are available, for various OSes and CPU architectures, per the requirements listed in the README. For most users (with a Windows machine on an x64 device), the GSE-win-x64.zip file should be downloaded.
