DOS Wasm X vs Magic DosBox

DOS Wasm X is a free, browser-based DOS emulator built around the DOSBox-X codebase and using WebAssembly. It provides virtual hard drive choices of 512 MB, 1 GB, or 2 GB and RAM choices of 32 MB, 64 MB, or 128 MB. The browser stores the drive so users can return later, and it can be exported as an image for local saving. Supported file types include ISO, ZIP, BIN, CUE, IMG, and 7z; users can import and export files and change a CD while the emulator is running. Controls include mobile mode, an on-screen keyboard, gamepad support, full screen, zoom, mouse capture, CPU speed and emulator time settings, and pause and resume. Audio, dark mode, and resolution resizing are also listed. Windows 95 or Windows 98 can be installed with the user's own Windows copy and ISO. The project can be hosted on a web server by copying the dist folder or run in a container using its Docker command. Before leaving after using Windows, shut it down within the guest system to save drive changes.

Magic DosBox emulates MS-DOS so users can play their own classic DOS games on Android phones and tablets; games are not included. Its on-screen widgets can send keys, emulate a mouse, pause a game, and perform other actions. Users can customize widget appearance, size, and position, then export or share game profiles and layouts. It also supports physical mice, Samsung styluses, external gamepads, keyboards, sound, IPX networking, and serial modem connections. Games can be configured through a simplified interface or Expert settings based on a modified DOSBox configuration. The app lists ISO, GOG, INST, and CUE files, and supports save states. Magic DosBox Lite is free, with three widgets and a limited number of games in the collection. The $3.99, paid once plan includes all widgets and removes the collection limit. The maker says Google Play's required storage access can be slower than direct access, while Android 11-based changes block mounting the storage root and Downloads folder.
