Game Guy - The Unportable Game Boy -- Episode 531

If anyone's interested, I've got a single Pico version here:

Having lots of fun with this.. thanks Andy!

Oh, man, that is seriously cool! I'll definitely be watching for the PCB. I'd love to make one of those once you've got it working.

It works! 

I have 9 more bare PCBs -- If there's any interest, I could put them up on ebay (cheap).

Awesome work.

What? That's amazing! Of course I'm interested. I don't need nine, but I'll take two off your hands. Please feel free to send me a dm and we can work out the details.

I am interested in this. Would love to take one.

Thanks for your work, i ordered your design by a PCB manufacture -- Works nearly flawless, only pressing all buttons at one time craches the GameBoy (for Tetris quick reset )

Is it an original NES controller?  I've noticed some differences between the aftermarket ones and the original that made the response a bit unpredictable. I think the aftermarket ones I saw kept the data line high when inactive and the original NES controllers kept it low when inactive.

With the active-high, it's probably more important to level shift the signal down for the Pico.  I forgot to do that on that PCB rev.  You could try cutting the NES Data trace and instead of going directly to the Pico, try passing it through the remaining level shifter slot.  You'd have to bend the pin (11) out of the holder though, so that it is no longer grounded.

It's been a while since I looked at that rev of the board.  I'll update that version with this change.

Also... Tetris has an auto-reset?  Wow, I never knew!  

If you press all buttons, try hitting Select as the last button. It might be my OSD* code causing the problem  

*For OSD, hold Select, then just tap Start

Thanks for your answer.

Yes it is an original gamepad (my socket looks different because i used a 4players adapter for parts).

Without hardwaremodification it still crashes even if i press select as the last one.

But now I have tasted blood and go for the V3 SMD version -- CPU and RAM has been transplanted. Now I am waiting for SMD resistors and crystals (because I use Super GameBoy for the parts)

The v3 board has no link cable socket, right?  

Correct, there is no link cable socket, although it wouldn't be much work to add to the PCB design. 

I think you'll like V3, I also recommend picking up a cheap ($5-6) MyArcade wireless controller -- it performs awesome for me.  Stay tuned to the element14 youtube channel -- I can't give too much information away right now, but there might be some updates very soon.
