What DOSBox 3DS is

DOSBox 3DS is a free port of DOSBox-SVN for Nintendo 3DS. It emulates a PC processor, sound and graphics hardware, and other peripherals so DOS-compatible applications can run on the handheld. Supported disk images include ISO, CUE/BIN, CUE/IMG, floppy, and hard-drive formats. Gamepad and audio CD support are listed. Emulated legacy audio devices include the PC speaker, AdLib, Sound Blaster, Gravis Ultrasound, and MPU-401. DOSBox can provide a serial null-modem connection over a network or the internet for multiplayer use. On first launch it creates a configuration file, and users can adjust CPU cycles, frame skipping, and sound settings. Host drives are not exposed automatically; directories must be made accessible with the mount command. The project notes that it does not run every PC program, uses one CPU core, and describes high-end performance as roughly comparable to a Pentium I PC. Source code and a COPYING license file are available, while the repository lists no releases.
