Well, well... some new parts just came out that would make MultiBoy32 a lot easier to build. Could be an interesting year in 2020. :-)

Orders for the test PCBs just went it. These are to check the mechanical assembly and the bonding of the ePaper display into the FR4 cover.

It will take about 2 weeks for me to have them in house.

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

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:
https://www.totallypromotional.com/square-power-bank.html

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.


Yes I did. Thanks!

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

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.

I never have eye strain from psvr. Iíve played hours on end of Farpoint. Did you set the software IPD?

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.

So it's a little unclear whether or not there will be the eInk display. I think that's really awesome. I saw here you said you're some it back, but on the page you said you would ommit it, not sure on the order of these. Cool stuff, Kevin!


eInk included.

I originally said Iíd let it go and not include it. Figuring out the FR4 case design allowed it to be added back. The only question now is monochrome black and white or black/white/red.

Project is continually evolving so youíll need to be OK with changes. If not, I advise to wait until the next batch.

If I understand correctly, with this latest design update, we can use the buttons on the cart to switch between games. Is that it?

If so, I am sold. I was holding out for the MultiBoy32, but if this will let me switch between ROMS without needing to plug the cart into a computer, I'm sold.

Also, if we don't need to plug the unit into a computer and the ROMs are stored on an SD card, what is the purpose of the USB connection?


You need USB for power. You canít flash it while plugged into the VB.

Iím open to suggestions for powering the cart when out of the VB.
