• New "Play from disc" setting (System > SwanStationPS5, off by default): a disc put in the USB CD drive is read into memory and played from there, with nothing installed. The game shows up on the shelf and starts by itself while the disc is in, and leaves the shelf when the disc is taken out or the drive is unplugged. When the whole disc does not fit, a window of up to 256 MB follows the game around the disc, reading ahead of it.
• LibCrypt discs work from the disc too: the .sbi patch is picked by serial, or by the disc's CRC-32 for the two games with two pressings.
• "Install discs only" is now "Do not start the game automatically": with it on, a disc only brings its game to the shelf (installed, or read into memory with Play from disc); with it off, the game starts. The disc daemon follows both settings, and with Play from disc on it installs nothing.
• "Install to external memory" is not available while Play from disc is on.
• A game running from the disc cannot be deleted from its Details: a notice says so.
• Games are also looked for in /data/homebrew/PPSA99248/games, and the BIOS in /data/homebrew/PPSA99248/bios when ours has none.
