Hi all,
the mandelbrot zoomer was actually just a testbed for that shrinked affine worlds in 13 dither shades approach. I only use it to write 2×2 pixels with a single byte store. It has nothing to do with the ‘3D’ or ‘perspective’ here.
Without that working out, the voxel engine would have been little fun.
After quite some time spent optimizing routines and rewriting the algorithms from scratch a couple of times, I feel that it had become fast enough to be actually useful:

(it runs considerably slower on real hardware compared to this mednafen recording but still at about 9 FPS).

You find the binary attached below:
It’s fully interactive (it would have been much simpler to code otherwise):
left pad:
left/right: rotate
up/down: forward/backwards
right pad:
left/right: strafe
up/down: increase/decrease rendering depth (starting at max).
This is fully written in v810 assembly (ISAS) and a couple of cache tests performed before also helped a bit.

The engine plots into a mosaic of 3×2 affine worlds for each eye, 12 worlds in total.
I will likely reduce the visiable area on the screen some more to bring it down to 2×2 and safe memory as well as CPU speed 🙂
The hex digits in the upper left are: time spent per frame (in 100us), depth (non-linear), rotation angle, xposition, yposition.

Hey there, all you fine folk! Figured y’all might be interested to hear that I got in contact with Virtual Lab‘s developer ‘Megumi-tan,’ after writing a history / review of their game in question. They get into a fair bit of detail about the game’s development, its publisher J-Wing, working with the Virtual Boy devkit, and other really interesting insights into their history in the games industry.

You can check out the interview transcript here, if’n you’re curious!

RetroOnyx have announced HyperBoy, a new single game 32MBit Virtual Boy flash cart. It’s based on RetroOnyx’s HyperFlash32 design, but drops the eInk screen, cap touch buttons, haptic feedback, and SD card to reduce cost and bring a cheaper flash cart out to Virtual Boy gamers. Think FlashBoy Plus but with twice the ROM space, more SRAM and no save battery needed.

Preorders for a limit run of the cartridge are open now! Deliveries are set to start in approximately October and run through December.

Features overview:

  • 32 MBit Flash memory
  • 32k x 8 nvSRAM
  • Aluminum anodized covers
  • 3D printed carbon fiber frame
  • Laser etched graphics
  • USB port for game loading

The Reality of Virtual Boy

After Nintendo achieved world-shaking success with its Game Boy handheld system, a next-generation follow-up seemed inevitable. Yet few could have predicted the form it would take—or how poorly it would fare with critics and consumers alike. That device, Virtual Boy, stands as a rare black mark on Nintendo’s long legacy of console hardware: An abject commercial failure, retired after only half a year of life. But was it really as bad as all that? 25 years after Virtual Boy’s rocky launch, this book provides a comprehensive and open-minded exploration of the Virtual Boy and its library from start to finish.

Packed with history, critiques, direct-feed screenshots, and complete packaging photography for the console’s entire library (and then some), this is the definitive chronicle of Virtual Boy’s history.
