Hey guys; I now have a Patreon account, so if you appreciate my work (Or if you don't, I don't judge) you can now support me on Patreon if that happens to be your thing. 100% of donations go towards buying hardware to reverse engineer, or tools to do so.

This is TinyTendo, a real hardware NES handheld that is the size of the original GameBoy. This is not emulation, it is not a Pi, it is not a NOAC, and it is not an FPGA. This is real NES hardware from a real NES. This project will also be open sourced in a few weeks.

And here we have the first go at turning it into an actual design. :) I opted for a pre built W5500 module instead of building it from scratch, saves time and makes it easier to validate. I was going to make it just a flex but the rigid + flex setup will make LTE easier later.

I am beyond disappointed to say that gutting PC10 and VS cabinets is a startlingly common practice in present day. If you absolutely feel like you must have RGB output from a NES/FC use a NESRGB or RGBBlaster. Do not use an RP2C03B or any other variant of native RGB PPU.

One of the hardest parts of this build was designing the housing. The housing took me over a week of 12hr days of 3D modeling to get right. And my underpowered computer at the time didn't help. While it was exhausting, I am happy I did it, cause frankly, it looks amazing.

Hey, I shouldn't have to say this but, quit putting Noctua fans in your original Xboxes. They move less air than the stock fan even when forced to 100% speed, and what was intended to be a fan "upgrade" is just a downgrade as your Xbox runs hotter. Just clean your stock fan. :)

TinyTendo utilizes real NES chips that have been physically cut and ground down smaller. A simple run down is that I sand away the bottom of the chip till I hit the die and leads, then I cut the chip smaller with a Dremel. The end result is 10x10x2mm, and surface mountable.

The original Xbox (as everyone knows) has a poor quality supercapacitor for keeping time that likes to leak. It is standard practice to just remove it, however on the "1.6" motherboard it won't boot if you do so. Well until now I guess, here's a terrible diagram for fixing that.

Due to an unfortunate mishap my Xbox power board blew up taking the trimmed motherboard with it. :( I've got new parts on the way, and I'll be continuing the project, but I've run out of time for it to be an entry in the Bitbuilt competition. It was fun while it lasted.

Wiring up the Xbox pixel bus by hand sure made me appreciate @MakeMHz flex PCBs even more.

Been working on a replacement S controller shell on the side based on @WeskMods 3D scans. The front half is nearly done. :)

The OpenTendo GitHub repository now has schematics for the NES-CPU-03 and NES-CPU-04 motherboard revisions. Only 05-10, and the Sharp NES TV motherboard remain. Once these are done OpenTendo will officially document every OEM and licensed frontloading NES motherboard revision.

@tomwarren Yeah but Windows. Anyone tried using Windows on this type of device? The user experience is HORRIBLE. If I'd end up installing SteamOS on it anyway may as well just grab hardware it's made for and even save a few bucks. :)

Now that's a lot sleeker, what do you think? I even managed to art a little.

Well that was a headache, yet another feature proved out for my portable Xbox. :) Now I just have to turn this into a sleek PCB/flex.

Just got a totally normal handful of NES CPU/PPU chips here, being used for totally normal purposes.

Well I made a dumb purchase today. Guess we'll see just how dumb it was when it gets here and I start patching it up. :) (At least it was only $45 before tax!)

This actually drove me to make it "reversible" I haven't uploaded it yet as I never can find the time, but I actually designed a PCB so that trimmed chips could be put back where they came from. As long as someone doesn't mess up trimming the chips, they can undo everything. 3/5

Anyone wanna see the process of turning this "ugly" piece of coal into a ring?

I'm doing some Xbox mods in exchange for all this, what do you think? :)

The new TinyTendo audio amp arrived and it fits perfectly (Plenty of room for the new battery setup). So all that's really left before open sourcing is wrapping up documentation!
