will it support folders on the sd card? I like to keep homebrews and Patched Roms separate.

Another question:
so these will completely work with the VB Programmer?


Folders- probably since my programmer already supports folders.

VB programmer support- it could with a firmware update. TBD.

Hawwwww snap. I have a flashboy so I didn't think I needed this. But that e-ink. VERY cool idea. power up the cart through USB, select the ROM you want using inputs and a display, self-flash. Hnnngggggg.

I'll be able to buy one in a couple of days, hopefully they're still available lol. Let me know if you want help with the soldering.

Have you considered something like this to power the display when the cart isn't plugged in to USB?

https://www.powerstream.com/thin-lithium-ion.htm

OR

https://www.mouser.com/new/Murata/murata-dmh-supercaps/

As long as there's _some_ room in the case you could add either of these. You could charge it with USB or even siphon some power off of the VB while the game is running to keep the battery or supercapacitor topped off. Unless people are sitting around flipping through screens all day without ever playing a game, there might just be enough power in one of these to operate the e-ink and game switching function the way most people would use them. When the power's about to be exhausted, have it switch to a screen that says "plug in USB to charge".

I would of recommended QI wireless charging but then buttons wouldnít be accessible.
Iím ok without a battery since you can plug into just about anything including smart phones to share power.

I did consider this previously. Iíve worked inductive charging into several designs in the past.

Good ideas. Not sure I can increase the BOM cost any further. Itís all ready too high. USB cable will probably have to be the solution for now.

Absolutely understand. You just put a call out for alternative ideas for powering the cart outside the VB and I thought those might be feasible. I would LOVE to see the cart be able to power itself through a couple dozen game switches and recharge through the VB while it's in use. That would make it more self-contained and mass-market friendly. It might be worth plunking the charging circuit and battery into the BOM just to see what the impact would be for sure. However scope creep has a way of killing these things, so I think the design is fine as it is.

Personally I have one of these:

It's not much larger than a VB cart so I'll probably keep it with a short USB cable next to my VB so I can switch games without having to fuss with a PC or wall socket.

I just added a couple more to stock but that will be it until after the first build.
