HoloVCS – Play Atari 2600 Pitfall! in 3D on a Looking Glass Portrait

Have a Looking Glass screen and want to try the above thing? Well, you can!

Download for Windows (~70 MB)

Github source

To run this, you need:

  • A Looking Glass holographic display device connected to a Windows computer via hdmi (designed for the Portrait, but in theory it should run on all of them…)
  • The Holoplay driver installed
  • A beefy ass graphics card
  • The pitfall 2600 rom (.a26 file) which needs to be put in the /atari2600 dir. For legal reasons I can’t include it.

I’ve only tested with the Looking Glass Portrait and the OG 8.9. They both seem to run around the same speed, with the OG 8.9 being too zoomed in initially. (try the – key to zoom out?)

How to set it up and play it

When it starts, it will show a menu with the hotkeys, but here they:

Gamepad/Arrow keys: Move
Ctrl/Button A: Jump
Return: Reset game
Num 0 through 5: Set frameskip (higher makes the game run faster)
A: Adjust audio to match game speed (experimental but can help with audio problems)
-/+: Zoom in/out. Hoping this will help with other Looking Glass sizes.
S: Save state
L: Load state

Speed is a bit too slow even on my 3090, so good luck. The frameskip options help though.

If you have problems, check the log.txt file. (created in the root dir where HoloVCS.exe is)

Q. Does it support other games besides Pitfall!?

A. Well, yes and no, yes it should emulate any VCS game, but the 3D layer processing is designed for Pitfall! so I’m sure it would be… quite the experience

Q. I noticed you’re using Stella’s libretro interface, does this mean I can pop in a NES emulator or whatever by replacing the dll?

A. In theory yes, but because pixel sizes/input/etc are kind of hard coded for the VCS I’m sure it’s going to hilariously explode.

Q. The snake is mostly invisible!

A. This is a known bug, sorry. I mean, it’s a ghost snake now

Q. The 3D effect is sort of cool, can I play this in VR?

A. Not yet but would be really easy to add support for that! Would run much faster too.
