What DOSBox 3DS is

DOSBox 3DS is a port of DOSBox-SVN for Nintendo 3DS, intended for people who want to run DOS software on that handheld. DOSBox emulates a PC’s CPU, sound and graphics cards, and other peripherals so it can run DOS applications. The project lists DOS-compatible software as its target. It can work with ISO, CUE/BIN and CUE/IMG disk images, as well as floppy and hard-drive images; gamepad and audio CD support are also listed. The emulated sound hardware includes devices such as the PC speaker, AdLib, Sound Blaster, Gravis Ultrasound and MPU-401. DOSBox can also emulate a serial null-modem connection over a network or the internet for multiplayer connections. Users can adjust configuration settings, including CPU cycles, frame skipping and sound. On first run, it creates a configuration file. Drive access requires a mount command to make directories accessible. DOSBox 3DS is free, with no free trial. Its source code and a COPYING license file are available in the repository. The project notes that it does not run every PC program and uses one CPU core; performance on a high-end machine is described as roughly equivalent to a Pentium I PC.
