uxnds

Quick and simple port of the uxn virtual machine to the NDS and 3DS consoles.

You can download the latest version and source code here.

Usage

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

On start, a keyboard is presented on the bottom screen, and the uxn display - on the top screen. Use the L or R buttons to swap them - in this configuration, mouse input is approximated via touchscreen.

You can use the system button in the lower-left corner to reset the uxn virtual machine.

Installation

Two ports are provided: the 3DS port (compatible with 3DS consoles) and the NDS port (compatible with DS, DSi and 3DS consoles).

3DS port

There is one binary provided: uxnds.3dsx.

To compile uxnds for 3DS, you may use:

  • the latest devkitARM toolchain from the devkitPro organization to compile. After installing, simply run make -f Makefile.3ds.

NDS port

When using a real DS, DSi or 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.

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.

To compile uxnds for NDS, you may use:

  • the BlocksDS toolchain - run make -f Makefile.blocksds;
  • the latest devkitARM toolchain from the devkitPro organization to compile. After installing, simply run make -f Makefile.nds.
