How this runs
The game runs through a DOS emulator inside your browser: the emulator, the files and your saves all stay on your device and nothing reaches our server. The emulator, the licensing and what to do about a black screen are explained on the retro games section page.
FAQ
Is this the actual 1993 release?
Yes, these are the original Master of Orion files, not a remake or a port. The emulator runs them the way they ran on a machine of that time.
How big is it and what loads?
The game archive is 5.3 MB plus about two megabytes of emulator. It loads once — after that the browser keeps the files cached and the next launch is instant.
Can I play on a phone?
Yes. The game uses a mouse, so on a phone your finger is the cursor: drag to move it, tap to click.
Are my saves kept?
They are, but only in this browser on this device — they are written inside the emulator. A different browser or a cleared cache means starting over.
