DOS Wasm X vs DOSBox 3DS

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.
