I second this. Some games have issues on ReARMed core. Diablo is lacking input controls. And framerates on Need For Speed III and NFS: High Stakes are unplayable at 1 to 2 FPS, even in the menus.

@Swordfish90 how hard it would be to replace the current PS1 core with Duck/SwanStation? If this is not desirable, could you please point me in the right direction so I can fork the repo and make the change?
