A plastic box with 3 cut-outs is essentially all this needed to be. Really…just a small box, a few cuts and some glue but no…this had to become the most elaborate 3D printed case to enclose 3 freaking connectors and a bit of wire…

I’m not sure what it is that pushes me to this extent to engineer a plastic box I’m sure I could drive over and not break, but whatever the reason this A/V & Controller breakout box for my SNES Box Go is a rugged “Sumbitch”.

Designed as a two-part case held together with mounting tabs and #2-56 hardware, the layout is sturdy and far stronger than it needed to be. Though, with all this strength, its weight is still lighter than I would have liked.

Essentially this is a two part case and utilizes 4 mounting tabs which most of my console cases do. The mounting tabs were glued to the base of the case and then set in place with screws. Very easy to get into should the need ever arise.

Again, this isn’t anything spectacular but was worth a mention and short post. I’ve got a few more projects in the works that are a little more in-depth and possibly a few commissions coming down the pipeline, so hopefully we’ll break this 3 to 4 month post cycle!

Hey guys! I know I know…been another 4 months since I’ve posted anything, but when it comes to time to work on a project or time to work on a blog post, you know which one wins.

That said though, these past 4 months have had me working on a new project that I’d never attempted before, and from what I can tell in my searches across the Internet, no one else has either.

The SNES Box Go is a relatively simple portable Super Nintendo mod, much like the N64 portables I’ve done in the past. The one key difference here is that this is my first time I’ve used a Flashcart in the build to load the games from ROMs instead of the actual cartridge. I’ve had a little experience with Flashcarts where I updated an old system of mine with an Everdrive 64 at the end of last year.

The reason I say this may be a first though is because I have yet to see anyone implement one of these Flashcarts into an SNES portable. Though this isn’t much of a surprise because the cost comparison between needing the original hardware & Flashcart vs an Emulator based system which usually run fine with games older than the N64, probably means this is a first. i.e…this isn’t a practical build for anyone who just wants to “play” retro games as much as it is just a fun project to build for myself.


The portable itself is based off an original SNES Jr. model. It was Nintendo’s late revision of the system shortly before the N64 came out and it had a much smaller motherboard that was ideal for making portable. The motherboard was not trimmed at all and fit well in the design.

Don’t freak, the system I had was bought broken off eBay about 5 years ago. I didn’t use a pristine version of this somewhat rare console.


The enclosure was designed around the mother board with zero trimming in mind. This actually worked well and ended up being almost the same height as the N64p mods I’ve done in the past. The only thing that was removed from the stock board (aside from the standard controller ports, cart slot, switches, A/V & power jacks) was the 7805 regulator as I swapped it out for a more efficient switching regulator that was installed on the back half of the case.

Of course the next main piece of hardware is the Flashcart itself, which is an SD2SNES by Krikzz who is based in the Ukraine. This is hardware that normally would be in a SNES Cart and then put directly into an SNES like a regular game. The main difference is that the system plays its games from an SD card that’s loaded in the top. So even though it’s playing off ROMs, it’s playing them with zero conversion or compression because they are being processed by the original system hardware. Basically, there’s no emulation taking place, so games run at full speed and the way they were intended originally. There are some exceptions with special chip games that the developers are working on through firmware, but it’s 99% compatible for the most part.

This was my first time wiring up cart slot like this (where the cart was perpendicular to the solder points on the system’s motherboard) so there was a lot of extra wire in my relocation. Didn’t cause any problems though, so I left it as was. Again, casing was designed around these parts so it fit nicely.


While on the topic of the Flashcart, I just want to take a second to thank Andy and Stoneage Gamer for sponsoring this project by supplying the SD2SNES! A huge help and I appreciate them coming on the 4 month process of building this! Check em out at They’ve got an amazing operation going on there and I hope to one day visit their store!


It’s a bit hard to see but the battery cover has the Stoneage Gamer logo SLA 3D printed in the back of it.



Keeping with my standard build practices, the enclosure is FDM 3D Printed while the buttons and decals (like speaker covers) were printed on the Form 2. Like the N64 portables, the case was printed in several parts and then glued/filled/primed and painted and fastened together to make the casing. 

Though the process was the same, this was without a doubt the most complex casing I’ve designed. Lots of tight tolerances due to the use of the SLA printed buttons as well as traps for the mounting hardware. Didn’t come out perfectly and sanding was a pain due to so many tight edges and seams. But I’m happy with the final outcome.


I know I’ve been saying this for nearly 2 years now, but the Form 2 is an amazing piece of equipment. The R & L buttons especially benefited from having this in house as they were far more complex in design than any other button I’ve designed to date.


I mean you can even see the L and R printed right into the button!


The power circuits are another bright feature as they are fully custom, utilizing both RDCs regulator breakout board for the TI PTH08080WAH as well as his battery charger board which was designed for the flat cell Li-Po batteries used to power the system. The cool thing about that charger board is it allows for the use of any standard 12v 3A power supply instead of the smart changer. Not to mention it’s Play & Charge ability allowing for the whole system to play off wall power as and charge the battery at the same time.


The batteries are the standard 3.7v 5000mAh Li-Po cell I pretty much always use, though the expense and shipping prices may be driving me elsewhere soon enough.


Standard 5″  640 x 480, 4:3 Aspect Ratio Screen, 28mm Mylar speakers, custom button board PCBs and custom Audio Amp. A new addition though is the 1″ x 1″ SNES controller PCB. This saves from having to trim down and wire to an actual controller board.


All wired up aside from the Flashcart. You may notice too there is a USB 3.0 jack. This is used just as a connector to the breakout box that allows for 2nd player and A/V out to a TV.


The 3D Printed breakout box inputs the 2nd player controller to the handheld and outputs the A/V to a TV.


A modified RCA cable and standard USB 3.0 handle the A/V and P2 controller I/O



Because this was such a large project and post, there will surly be updates to it as well one more video that dives a bit deeper into the tech and features of the system. 

Until then, thanks for checking this out and I hope to hear your thoughts about the system and process!



Some would say this was a long time coming and truth be told, this should have come a great deal sooner…but knowing what follows when releasing a custom casing designed around custom components, the flood gates that open go far beyond just supplying a design file. This has honestly been the biggest issue I’ve had with making only a partial design public, because inevitably the emails and tweets will come in asking for the rest of the parts, links to the components used and then advice on how to put it all together.

This was one of the exact reasons why the idea of a full kit was put in place years ago and still being worked on today, but of course the interest needed to make it a reality and economical (i.e. needing lots of money for them) is in direct competition with those who just want the case files (i.e. don’t want to pay). It’s kind of like not being able to get out of your own way.

So then it hit me. Meeting halfway at this stage of the game is pointless. The kits won’t succeed unless there are people to buy them, and generating interest to a very limited group willing to pay for the convenience of a kit is even harder.

100’s of hours have gone into revisions of this case design since it first emerged in early 2015. Every detail was built from the ground up, revised, tested and improved with each version. And not just the casing, but the custom components, the addition of SLA printed buttons, decals and covers and even new finishing techniques have made this N64 design my baby of my modding “career”.  Giving it away has just seemed very hard to do, especially knowing that as soon as I did, people would be knocking at the door asking for more.

But things changed a few weeks ago. I sold off a few of the older version cases I had printed a bunch of when I was about to start trying to sell a few kits, and then the design had a major revision on many levels. But as part of the sales agreement, I provided a parts list of the basic components for the customers so they could source on their own. And then suddenly, once that was there I had a resource that anyone could use as a reference.

In turn this lead to a solution that didn’t require a “meeting halfway point”. The older designs still use a majority of the basic components as the current kits do, so using all the custom components that would come with the kit wouldn’t necessarily take away from ones ability to build one with some modification. And let’s face it…modding is about seeing what you can do, not 100% about your end result.

So here it is! The full set of STL files for a complete Legacy version of a Downing Style Portable Nintendo 64! (download here)


Alright, so first let’s explain what the “Legacy” casing is.

First and foremost, this is about 3 minor versions behind the current kit version which is why it’s called a “Legacy” version.

Second, what is provided is what you get and you will find it difficult in some cases to find parts that are going to fit properly because in the instance of buttons and decals, they were all custom designed and printed in SLA. You WILL have to hack this case to make make work without these parts, but the Parts List can help you out for most of the off-the-shelf parts that were used. I can provide a set of SLA printed buttons and decals that can make your day easier, but both the resin needed and the time to print carry a cost.

Third, included in this list of STL files are enclosures for 2 custom power supply solutions for this model. One of the big changes between this version and most recent is the custom battery charger PCB which allowed for a single 12V, 3A input to power everything. The Legacy version utilized a standard type A USB jack to use both wall power and battery charger at the same time by using two different sources. One of the enclosures allowed for both the battery charger and standard 12V PSU to be stripped and wired up inside and fed to the system via stand USB cable, and the other was an adapter that took both power supplies and their standard plugs and fed them into unit that way.

USB power adapter. Smaller and easy to wire up, but don’t plug wall power into the battery charger port! (hence why this idea was short lived)


The Power Brick. A one and done solution by the wiring of a 12V, 2A  power supply and the smart charger for the Li-Po batteries. An ideal solution for a one-off, but not a kit as this case takes over 8 hours to print on its own!

Aside from the custom battery charger which is included with the current kits, this method is the one I’d recommend, only because when wired up correctly, you do not need to worry about mixing up two different power supplies.


Again, though I hope to have a “Legacy” sub-section in the main guide, time is something I have very little of these days and I still have to get the main section fully updated before this is worked on. That said, this means support on these and the techniques used to make them is going to be limited for a time to come. Use this as more of a “general idea” if you do decide to download the files.

I want to again thank everyone for their interest in this and sorry for it taking as long as it has to release a more recent version, but you can at least know now the road blocks that have been in my way for a long time now. I hope you find these useful and a good starting point if you’re just getting into the hobby of console modding!



Times like these are few and far between, when a project manages to come full circle and is then sent off to start another circuit.

The SG-N64 was a unique project in its own right, mostly in the sense that there was a guy dumb enough to build a portable system out of original hardware and limit it to a single game. Call it a passion project (which it was), but it still had no practicality in doing so. Still, the project found a following and even a few years after its release is still one of my more popular videos.

Now, a few weeks ago this system had been purchased by someone on eBay, and said someone somehow found my contact info which he described a new plan for the old console. The idea was to take this “Single-Game N64” system and turn into an “Every-Game N64” via the use of an Everdrive. Now granted this goes against everything this system was built for, I said yes because really it was no longer my call and it was something I hadn’t tried before.

I just found the irony perfect that with all the portables I’ve made and sent out, the first one to come back requesting this kind of mod to play “all”, was the unit designed to play only “one”!

Aside from this, the project was going to be a slight challenge because taking a scaled back system tailored to run a single game was going to take some serious tweaking to play the entire library of N64 games. But, as it turned out, the mods were fairly easy to implement and an old project got a fresh start with some pretty badass improvements!

Hopefully the buyer will be as happy with the results as I am! The video explains the fine details!

It’s been 10 years since I first got into the hobby of console modding and for a long time now, I’ve wanted to go to an event like MGC or PAX East. Never really had the time or money to make it happen though, but this year things seem to have fallen into place and I will be attending the 2018 Midwest Gaming Classic, April 13th – 15th in Milwaukee, WI. It’ll be my first time ever making a trip to the Mid-West and I will be meeting up with several other modders from the BitBuilt Forums who will be showcasing some very cool projects!

I don’t really know what to expect or how the process works when it comes to doing a showcase, but I will be bringing a small 3D display I’ve been working on that shows off all the details of the new Portable Nintendo 64 Kits I hope to make available. This will allow those who might have interest to get a better look at how the project would go together and also serve as an interest gauge so I can find out what level of actual interest there really is. But if nothing else, the experience of being able to “Geek Out” with others in person for a change will be a fun experience.

Building The Display

The display itself was actually quite the project in its own right. Basically just a sliding frame that holds each of the 4 case components which have all the parts already mounted in place. Made up entirely of custom designed and 3D printed parts and #4-40 hardware. There are 8 knobs on 4 sliding carriages, mounted on 2 rails supported by 3 legs. This holds each case component so they can be rotated and moved back and forth so everything on the inside can be seen.

The Completed Display Frame

The first version of the “duck” clamp before I realized I needed a bigger bill. These were two separate parts joined together with #4-40 nuts and machine screws.

The duck army grew!

The rails were then attached to the legs and the duck clamps attached to the rails. The rails also ended up being changed out for a version that had 4 slots (one for each duck) instead of 1 big slot because it was too flimsy.

The duck was also modified with a larger bill and a nut trap to make single handed loosening/tightening possible.

The last step was printing 8 knobs and gluing in a #4-40 hex bolt in place to use for the tension knobs. This worked surprisingly well.

When it was time for it all to come together, I was very happy with the results! For getting a general idea of what goes into these systems, a 3D Exploded View lets people get a very good idea of what goes into the process.

Leaving as little to the imagination as possible in this case is a key feature.

I’ll still be making tweaks to this before April arrives but for the most part I’m happy with it.

Building A Finished Version of The Kit on Display

That being said, I’m also about 80% complete of another N64 Portable which I hope to show off right next to this as an example of what the finished product can look like. This one also includes some of the biggest revisions to the design that have been done yet, including a new power system which ditches the 2 power ports and utilizes a custom battery charger/adapter as well as a new version of the Mini Controller board which has a built in memory card!

Yes it’s stuff that most people aren’t going to see or know about, but when it comes to building one, these improvements take tons of time and wiring out of the equation. And this one happens to be one of the prettiest finishing jobs I’ve done so far. Can’t believe I’d never done any kind of wet sanding before and here it makes all the difference! It’s a beautiful thing! Hopefully in the next few weeks I’ll have a video of both side by side as a glimpse of what MGC may look like at the BitBuilt table in April!

The Front Face Assembly looking sharp!



Wow, over 3 months without a post! Yeah the real world is taking up so much of my time to actually work on any projects at all, it makes it next to impossible to make posts and build logs. But that being said, in the past week and a half I managed to finish off and ship out two large projects that I’ve been working on the past few months.

The first to ship was a pilot run of (4) N64p Kits that I’ve been working on developing for quite awhile now. I can’t say too much on this yet as there are a few more details that would need to fall into place to make this work, but if it does there may finally be a viable option for DIY modders who want to try their hand at building one of these with a fraction of the guess work. Again though, more on that later.

The second of course was my 8th Portable N64 Commission and my 4th this year alone. It has been a great deal of fun but they have been a lot of work. Fortunately though, the design of each system has been consistent enough that when I put this last unit together and fired it up, everything worked on the first try!

So sorry this post is kind of short, making that video took up most of my free time today and Christmas Parties are on the agenda for this evening so I have to get ready for those, but at least you know I’m still working on projects when I can! Thanks again and there will be more posts soon!
