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.
