The Virtual Boy is almost 25 years old and it still has some love!

The Virtual Image Processor (VIP) in the Virtual Boy is only capable of outputting monochrome images. I doubt the VB hobbyists here will make a color version that can output better graphics, but Nintendo's own attempt was too expensive in 1995, so they just used red LED's as they were the cheapest kind, and that disappointed everyone from the beginning.

There's a VB hardware reference made by Guy Perfect:
http://perfectkiosk.net/pvbemu/stsvb1.html

One of the main differences is the CPU. The VB has a 32-bit NEC V810 CPU (with a few custom instructions added). It's essentially a cut-down MIPS CPU.

The Virtual Image Processor (VIP) has a 50 Hz interrupt used for timing. Note that the mirrors in the VB scan horizontally, instead of vertically.

Like the subject/title says, has anyone decapped any of the VB's chips (CPU, VIP, VSU, etc.), and posted pictures of the dies online?

I've also been wondering what the pinouts of the chips are. The NVC CPU is literally just an NEC V810 with some added opcodes, so the pinout should be similar, and thus understood.

Why wasn't M.K. active here for several months now? His projects are all die-hard-waited stuff, including his music tracker and Bomberman clone for the VB.

Although the VUEngine project had recently got a music/sound update, M.K.'s tracker will be more powerful, I think.

I was messing around with Red Alarm a bit, and it turns out the game IS actually running, it just doesn't draw anything to the console before reaching the title screen. If you press A a couple of times in the dark, and F5 in and out of the debugger, you can see the framebuffers gets updated with all the precaution graphics, but not the console itself. Of course the CPU window also highlight alot of exceptions all the time...

It's actually kind of playable after that :)


Question: Does Red Alarm put graphics data in any of the other tabs besides the framebuffers' tab?

The resolution of the Virtual Boy is 384x224, not 324x224.

Guy Perfect has a modern (and more accurate) version of the Sacred Tech Scroll that's still really useful for providing basic info on how to develop for the Virtual Boy's hardware:
http://perfectkiosk.net/stsvb1.html

However, this doesn't provide any documentation on how to use the various homebrew dev tools that are out there; it's just providing hardware-related stuff (CPU / VIP / VSU / communication port / game pad / timer / wait controller).

Also, and for music-related stuff, M.K. is current making VB Music Tracker.

M.K., the guy that created the GameBoy emulator for Virtual Boy, is working on a VB music tracker and a game.

I'm more excited for his tracker. His plan of releasing it last week in March has died, most likely because of more additional bugs he needs to fix before it's ready to release.
