The MOS Technology 6502 was one of the more popular processors of the 1980s. It ran the Commodore 64, the NES in a modified form, and a whole bunch of other hardware, too. By modern standards, it’s barely fit to run a calculator, but no matter – [Nick Bild] built a VR game that runs on the retro CPU anyway!
[Nick]’s project is built on his 6502 computer, the Vectron 64. Being a breadboard build, it’s easy to modify things and add additional hardware, and that’s precisely what he did. The VR system uses two 320 x 240 LCD screens, one for each eye. These are controlled over SPI, but the humble 6502 simply doesn’t have the speed to clock out enough bits fast enough for a video game. Instead, additional hardware is added to generate pulses to run the screens. There’s a bunch of other neat hacks as well that help make the game playable, like overclocking the CPU to 1.75 MHz and drawing common elements to both screens at the same time.
To test out the VR system, [Nick] coded a basic Asteroids VR game. It’s not really practical to demonstrate the game without the hardware, but we’d love to try it out. There’s something compelling about a low-resolution VR game with 8-bit graphics, and we hope to see the concept further developed in future.
More grunt would make this project even more capable, and for that, a 6502 running at 20MHz could come in handy. Video after the break.

I realize that biased reporting is practically ubiquitous in the media today, but I did hope this site was one of the holdouts. However, it turned out differently. Mentioning Commodore while not mentioning Atari? I am so disappointed…
dahh,, KIM1?? everyone else was late
Oj, yeah there was one other little company using the 6502..you prpbably never heard of them…named for a fruit.. Pear or Orange or something…
I still have my 6502 assembler guide around here somewhere, though the last assembly programming I did was sometime in ’85 or ’86, modifying an embedded mumeric keypad listing from a Nibble issue…
Elite would be killer on this.
RetroVR would be perfect in a Minecraft world.
Ever played minecraft in VR? ^_^
ViveCraft is pretty bloody awesome (at least it was in its time, I should really check some time if it’s still maintained..)
Even though it’s an awesome way to kickstart one’s Arachnophobia.. O_o
