Any idea on what the final cost might be? Will you sell these as a set or allow us to pick up one or the other? Will they come in any color choices? Do you guys have plans to include a homebrew or two?

Cheers!

It still needs a receive and send program and a connection.


That's only one possible application, albeit a very cool one. I guess it could also be used for debugging, cart dumping or for using the Virtual Boy as a 3D display device for the PC, like Alberto Covarrubias' veGL. :)

Thanks for the comments, guys.

Yeah... when I built my first prototype VB<->PC cable years ago, a ROM dumper / memory reader/writer / remote code executer was the first application I wrote.

The hope was to make a simple debugging interface with watchpoints and stuff, but after spending a little bit of time on it, I decided rather than reinventing the wheel (poorly), I should invest the time in making it work with GDB. Unfortunately, I don't have a lot of experience with the inner workings of GDB, and it seemed pretty complex. :/

I don't remember if Alberto ever released his Virtual-E project with the USB link code added, but it's pretty cool rendering things in OpenGL on the PC and viewing them in 3D on the VB.

Cost is still up in the air (highly dependent on the molded part cost), though of course I'm trying to make it as affordable as possible. I'm expecting to lose money on this (or at least not recoup it for many years), but it's something I really want for myself as well as for the community.

The plan is to sell the link cable and USB cable individually (and even as raw connectors/pins if you want them for your own project)... and if the manufacturer can do them in multiple colors, I'll probably consider having red and black connectors... but if it adds significant cost, they'll probably stay all black. The next prototype will be in red though, so we'll see how that looks.

I'll have homebrew examples for download, which you can load onto your flash cart to try it out, and also to see the code for using on your own homebrew.

How did you do that? Wouldn't you need specially programmed ROMs to do any communications?

Can data be transferred fast enough for full VB-quality video? If so, then who needs an Oculus Rift? :P Also, it would then be possible to display video from the VB on the PC and record it (with hacked ROMs, of course).

Excellent news! I especially like the part about getting loose shells/pins to hack with I'm sure those of us who truly appreciate your effort in this will make sure you at least recoup your losses very soon after release.

Re: other colors — If you're getting them made in ABS, there is always vinyl dye for those who want other colors. People have been using it for years to mod consoles and controllers. Unlike paint, it actually becomes part of the plastic itself, so it won't rub or flake off. I don't know how well it works on black, though, so maybe "natural" or white abs would be better (if it ends up being cheap enough to do two colors).

Well yeah, I wrote the code, and used it in homebrew stuff (you couldn't read/write memory while running an unmodified ROM). The ROM dumper ran from RAM, so you could hot-swap the carts. Of course if you modified a ROM, you could do this stuff while the game ran. I was going to try that to do save states, or a Game Shark kinda thing, but never got around to it.

The speed of the link port (on the one VB I tested) maxed out around 280kbit/sec, so no... uncompressed full frame VB video in/out wouldn't work in real time. Each display is 384x224x2bpp, so 172,032 bits per display, or 344,064 bits for both displays... so it'd take over a second to read or write a full display. For full quality video, you'd want to use the data bus (which could easily do it with something like an FT2232H on a cart).

I don't remember exactly how Alberto was doing his, but I think he used LZ compression, and only transmitted the chunks of the display that were being used... so it was usable for some cases (IIRC, his demo used a shaded rotating cube, which compresses well compared to a random bitmap).

Looks Awesome DogP and Hedgetrimmer you both have done a phenomenal job. If payment can wait till march I'll want a link cable and 3 USB cables. That is if you will you be able to play multi-player games (greater than 2 player) using the usb link and a multi-usb hub for your computer? Otherwise I'll just want a link cable and a USB link cable.
