Yes that's correct. You have to have a custom cart with the appropriate code. You can't just plug in any old cart and expect to dump or program. That's why I mentioned it would work with a custom cart I have.

Looks really great... I hope you're able to get these things into people's hands. As it sounds like you've found out in the other thread, creating a "run" of them to sell gets very tedious and time consuming vs. just putting a few together for yourself.

I see you're using an Atmel... not that there's anything wrong with them, but if you're not tied to that MCU, a PIC MCU may simplify the hardware a bit. For example, here's the USB MCU board I made: http://www.planetvb.com/modules/newbb ... t_id=34533#forumpost34533 , using a PIC16F1455. It runs directly from 5V, has hardware USB, has an internal oscillator that's good enough for USB, etc. Basically your BOM consists of the MCU and a few caps/resistors. It all easily fit on a single side of the board.

Thanks for the tips! I've used Atmel, Microchip, Stmicro, nxp, and some others. I'll check out Microchip for review.

Yes the builds are work but don't get me wrong, I enjoy them. I do this stuff for fun. It's more interesting with a 1 year old. I build late at night after kids and wife go to sleep.

USB link cable PCBs have come in and they fit perfectly into the existing connector housings. I'll be building the first few this week.

OK, finally got back to this. Got the board up and running and I'm switching back and forth between player 1 (master) and player 2 (slave) modes via a terminal program on the PC. Streaming data to/from a VB running DogP link cable test code on a Flashboy+, and my PC. Still some kinks to work out but getting closer to putting two VBs on the network to see what the games do.

There's two LEDs on the board. One of them glows red or blue depending on whether you're player 1 or player 2. The other LED pulses amber if a byte is coming from the VB to the board, or it pulses green if a byte is being sent from the board to the VB. Those will stick through the connector housing to give you an idea of what's going on with the USB link cable.

I'll need to spin the board to make some assembly updates and fix a connector flip (doh!).

since this cable has to hook up to a computer could we have 6 ft of cable?

It's a 6' cable now. Extensions should work too.
