unxds is a port of the Unx virtual machine to the NDS. Uxn is a portable 8-bit virtual computer inspired by forth-machines, capable of running simple tools and games programmable in its own assembly language.

This emulator allows you run to your uxn projects on the DS, also ideal for developers who want to learn how to program little 8-bit things, such as text editors, music trackers, illustration programs and games.

Installation

There are three binaries provided:

  • uxnds.nds - faster, but best used only with known-good software,
  • uxnds_debug.nds - slower, but provides debugging information, profiling information and performs CPU stack bounds checks.
  • uxnds_profile.nds - almost as fast as uxnds.nds - with debugging/profiling information, no CPU stack bounds checks.

By default, uxnds will run /uxn/boot.rom. It also supports reading files from within /uxn.

Note: When using a real DS/DSi/3DS console, it is recommended to launch this program via nds-hb-menu - though, as it currently doesn't use argc/argv, it doesn't really change much.

User guide

On start, a keyboard is presented on the bottom screen, and the uxn display is on the top screen.
