Retro-DOS
What it is
Retro-DOS is a DOS games launcher and emulator for handhelds, built on DOSBox-X with an SDL3 and Dear ImGui interface. Its library organizes DOS games and applications with an A–Z/0–9 index and search. Games mount as C:, and the launcher uses a game's own dosbox.conf when present or selects a runnable from its directory. The app includes Windows 98 and FreeDOS setup walkthroughs and can boot a hard disk image from C:. Physical gamepads and on-screen controls are supported, with per-game mappings, presets, and in-game remapping. RetroMedia can fetch box art after sign-in; administrators can download games where the platform allows it. Downloads are gated by platform and account and are unavailable in App Store builds. On Android, users can select a persistent read/write folder through the system picker or use app storage on any volume without granting storage permission. The Linux desktop build uses system SDL3. The iOS build disables dynamic CPU cores because iOS does not permit memory that is both writable and executable. The project is marked GPL-2.0; bundled FreeDOS and demonstration content have separate terms.
