Just a day after the release of the PlayStation Classic, the Retro Gaming Arts YouTube channel has discovered that you can access the emulator’s settings menu by plugging a keyboard into a free USB slot and hitting the Esc key. Doing so reveals a host of settings for the built-in open-source PCSX ReARMed emulator, potentially allowing access to options, including save states, controls, and cheats.
For those trying the PS Classic keyboard trick – if you find a working keyboard besides the Corsair K70 and 95, let me know! I took the PSC to a shop and tested 15 keyboards and none worked. They didn’t have those particular Corsair models.
