Dr. Mario
You supply your own Dr. Mario (Japan, USA) (Rev A) dump. It is read in the browser and never uploaded. The 65,536-byte ROM body must be sha1 59b43881456c0720e9a35e391b11c4b2c55a8f91; an iNES or a NES 2.0 header are both fine.
Files are read on this device. They are never uploaded.
Keyboard and mouse recommended.
The game downloads only after you press Play. Sound starts off.

The cartridge has no battery, so there is nothing for the game itself to save. The page keeps an automatic save state in this browser's IndexedDB, keyed by your ROM's SHA-1, and resumes from it next time. Clearing site data removes it. Save inside the game before exporting a backup. Clearing browser data can erase progress.
