Save and Load in DOS Games

js-dos offers you a great and free service to play DOS games. Many DOS games are fantastic and can provide hours of gameplay. Obviously, it's not possible to finish these games in one session. Luckily, js-dos fully supports saving and restoring game progress.

First things first: DOS games were developed at the beginning of the gaming industry, and typically they do not have auto-saving or continuous saving while you play. You should explicitly save your progress within the game.

To save your progress, you need to follow the game's original saving mechanism, as js-dos emulates the DOS environment, allowing games to run as they did on original hardware. Here's a general approach you might find helpful:

1. Access the Game's Save Menu: Most DOS games have an in-game save option. This is usually accessed through the game's main menu, which can often be brought up by pressing the "Esc" key or a specific function key (e.g., F1, F2, etc.). From there, navigate to the save game option using the arrow keys and select it by pressing "Enter".

2. Use In-game Commands: Some games, especially text-based or adventure games, allow you to save by typing in a save command. Common commands include "save", "save game", or something similar. After typing the command, you might need to specify a file name for your save game.

3. Check the Game's Manual: Since the saving process can vary significantly from one game to another, it's a good idea to check the game's manual or any available help files. These documents often include specific instructions on how to save your game. Manuals can sometimes be found online or within the game's folder on dos.zone.

4. Keyboard Shortcuts: Some games implement quick save/load features through keyboard shortcuts. Common shortcuts include pressing keys like F5 to save and F9 to load (though these can vary). Try to look for these shortcuts in the game's manual or settings menu.

5. Emulator Options: dosbox-x also offer specific options for saving your game state. This feature saves the exact state of the emulator, allowing you to resume from the exact moment you saved, regardless of the in-game save system. Look for this option in js-dos sidebar. (dosbox-x only!)

Great, your game progress has been saved! To load it, simply follow the same load mechanism provided by the game.

Keep saves between page reload

After saving the game using the game's built-in mechanism, you should explicitly inform the JS-DOS player that the game saves have been updated and that you want to store them persistently (in the cloud, IndexedDB, etc.). To do this, you must click the "diskette" button in the JS-DOS sidebar. If you do not do this, your progress will be immediately lost upon restarting the page.

Upon successfully storing the saves in persistent storage, you will receive a green toast notification. Now, you can reload the page, and your saves will be retained!

Keep saves between sessions/browsers/devices

For non-subscribed users, js-dos offers a free service that stores your saves inside the browser's IndexedDB. However, this has limitations: it only works within the same browser, and the saves can be wiped suddenly by the browser.

For subscribed users, saves are automatically stored in cloud storage and will be available on all your devices.

Wait, I don't see save button in js-dos sidebar

This means that the game works over a FAT network drive, which is a feature typically used by large games. The FAT drive is fully managed by js-dos cloud, and all changes made to it are automatically stored in the cloud. This means that to save and load your progress, you need to follow the DOS game's built-in mechanism, and js-dos will take care of your saves automatically.

For now, this feature is available only for premium users.
