You just pop in a USB flash drive with a prepared script, and off you go. The advantage of gaining command execution through USB is it’s easy for users to exploit. The GPG keys are stored on the flash to allow authorised update providers to run update scripts on the PSC to make changes to the file system - as the PSC has no network connectivity. These projects rely on executing an arbitrary shell script on the PSC by encrypting and signing a script with GPG keys and a passphrase that is stored on the flash in /root/.gpg. Googling for “hack playstation classic”, you’ll come across projects like BleamSync and AutoBleam for loading up extra game ROMs. Essentially the PSC is a Raspberry Pi with a couple of USB controllers. It is a fork for ARM processors of the PCSX-Reloaded emulator. The console runs an open source emulator called PCSX-ReARMed. The PSC comes with 20 game ROMs stored on the flash, and they’re loaded into the console emulator from the retro looking UI. Unlike modern gaming consoles, a minimal amount of effort has gone into securing the console. It comes with a cool miniature version of the original console casing, and two controllers. The PlayStation Classic (PSC) is a hobbyist gaming console - for the nostalgic types.
