Net SD card

Net SD card lets the emulators on your Android phone or handheld play the games stored on your computer, as if they were on an SD card.

Keep your whole game library on your PC. Net SD card shows every game to your emulators and game launchers. The first time you open a game, the whole game downloads to your device, so it then runs from local storage like any game on an SD card. When the space you set for games fills up, the games you played least recently are removed. Games you pin always stay.

HOW IT WORKS
• Share your games folder on your computer: Windows, Mac, or Linux (SMB file sharing). A guided setup walks you through it, one question per screen, and checks the sign-in before saving anything.
• Pick a game in your emulator or game launcher. It downloads when you open it.
• Play. Your save files sync back to your computer, so progress survives removing a game or switching devices.

FEATURES
• Your whole library: every game on your PC shows up, with its real size, and costs no space until you open it.
• Works with the game launchers ES-DE, Pegasus, and Daijisho, and with emulators that read games from a folder.
• Clear messages: if a game can't download, the screen says the real size, what to do, and gives you a button for it.
• Away from home: with the free Tailscale app on your phone and your computer, your library is reachable anywhere.
• Mobile data aware: downloads ask first on mobile data.
• Status screen: whether your computer is reachable, storage used, library size, and your license at a glance.

PERMISSIONS
• All files access: Net SD card puts the games it downloads where your emulators and game launchers read them, and copies your emulators' save files back to your computer. It uses this only for those game and save folders.
• Notifications: shows download and save sync progress.

PRICE
Free for 7 days with every feature. After that, Pro is a one-time in-app purchase. Games already on your device always keep working.

Net SD card does not include any games. Use it with games you own.

Requires Android 13 or newer and a computer on your network that shares a folder (SMB).
