KEEP YOUR ADVENTURE

Your PlayStation memory card.

Use the game’s save rooms to save normally. Card 1 stays in this browser on this device. Download a backup before clearing site data or moving to another browser.

The memory card becomes available after the game starts.

    Raw 128 KiB PS1 cards. Java checkpoint JSON and emulator save states use separate formats.

    Click the game before using the keyboard. The toolbar offers pause, controller mapping, volume and fullscreen. Use the left guide and item finder to check a location without leaving the game; optional cheats are on the right. Emulator save-state controls are hidden to protect memory-card progress. Connected gamepads and touch controls are supported by the player.

    SAVE IN THE GAME FIRST

    A card, not a snapshot.

    Saving the card to this browser preserves what the game has written to Card 1. It does not create a new in-game save wherever you are standing. Enter a save room and complete its save operation first.

    The page checks card format and confirms browser storage writes. Invalid imports are refused before replacing a card. Play in one tab at a time; private browsing and storage restrictions can prevent persistence.

    Card files and your gameplay remain on your device. They are never uploaded to COSOM.

    TWO EDITIONS, SEPARATE SAVES

    The original and the rebuild.

    This player runs the supplied USA disc through EmulatorJS / PCSX-ReARMed. Its raw PlayStation card is separate from the eight checkpoint slots in our unfinished editable Java/HTML5 rebuild.
