Super Mario 64 DOS Port

This is a novelty port of the sm64-port to DOS. Do not expect it to be playable.

Building Instructions

FunKey S

Simply go to this webpage and follow the instructions.

Docker

  1. Install Docker
  2. Build image: docker build . -t sm64_dos
  3. Run build: docker run --rm --mount type=bind,source="$(pwd)",destination=/sm64 -ti sm64_dos make -j4 ENABLE_OPENGL_LEGACY=1

Other

Consult the Dockerfile for required libraries and steps.

Notes:

For best performance:

  • Use ENABLE_OPENGL_LEGACY=1 to enable the legacy OpenGL renderer
  • Use DOS_GL=dmesa to enable 3Dfx-backed OpenGL instead of software-backed (this only works with legacy OpenGL!)
  • Set draw_sky to false in SM64CONF.TXT to avoid drawing the skybox (saves a lot of cycles in software mode)
  • Set texture_filtering to false in SM64CONF.TXT to disable linear filtering (saves a lot of cycles in software mode)
  • Set enable_sound to false in SM64CONF.TXT to disable sound (saves your ears from an untimely death and some cycles too)
  • Set enable_fog to false to disable fog (saves a tiny bit)

You can change the maximum amount of skipped frames by changing frameskip in SM64CONF.TXT.

You can change the resolution by changing screen_width, screen_height.

In software mode the only resolutions that will work are 320x200 (mode 13h) and 320x240 (mode X). In 3DFX mode the list of supported resolutions depends on the card, 640x480 is a safe value.

Use ENABLE_SOFTRAST=1 to enable the experimental custom software renderer. It can be faster than DOS_GL=osmesa in some cases, but might be much more buggy.

3Dfx mode:

When DOS_GL is set to dmesa, the game will render using FXMesa, which uses 3Dfx Glide for rendering. That means you will need a 3Dfx card (Voodoo II and above recommended, but will run on a Voodoo I probably) and appropriate drivers to run it.

The drivers can be obtained from this repository (see this file). Put the appropriate glide3x.dxe file next to the EXE.

When running Windows 9x, you will have to reboot into DOS mode before running the game for this to work.

dosbox-x and PCem can emulate Voodoo cards for testing purposes.

Running

  1. You'll need a copy of CWSDPMI.EXE alongside the executable.
  2. Either cp build/us_dos/sm64.us.f3dex2e.exe . or symlink ln -s build/us_dos/sm64.us.f3dex2e.exe sm64.exe
  3. Run with dosbox sm64.exe or try on some real hardware.

Controls

Controls can be edited as per the PC port, tweak the SM64CONF.TXT which is created with defaults upon first run.
