Loading Files

Use these three menu items to upload files from your device:

• You can upload multiple save, cheat, patch, and rom files at once from your device.

  • save, cheat, and patch files must be named the same as your rom file
  • rom files can be loaded from urls (one at a time), such as this one

• When you load a rom file, the selected game will boot and you are ready to play!

Use this menu item to load rom files that have already been uploaded to your file system:

In Game Actions

After you load a rom file and your game has booted, the following menu items will become available:

Here you can:

• Save screenshots to your local file system
• Enter full screen mode on desktop
• Download the current save file
• Quick reload the last used rom file
• Create and manage save states in your local file system
• Manage in game cheats saved to your local file system

Saving the file system

As you play and save your game, create save states, add cheats, add new roms etc. you will want to periodically save the files in your virtual file system to your device.

All files are stored in IndexedDB (browser storage), which will save if:

• you explicitly save the file system
• you save in game (automatic if the file system setting is enabled, ON by default)
• save all files when you perform a file system action (automatic if the file system setting is enabled, ON by default)

When your files are saved to your device, and you close and reopen the emulator, your files will be there right where you left off!
