Super Mario Bros. 35 Lives Again With A Fan-Made Server

June 13, 2021 by 27 Comments

If you liked playing Super Mario Bros. 35, the unique multiplayer battle royale Mario game that Nintendo released last year on the Switch to celebrate 35 years since the original NES version of Super Mario Bros, then it’s likely that you have been disappointed since April. The gaming giant ended support and removed the game’s servers once their 35 year celebrations were over, leaving the game’s players hanging. Happily there’s a solution, because [Kinnay] has presented a reverse-engineered Nintendo game server replacement along with a game patch, that should keep gamers in multi-Mario fun forever.

While it’s a boon for fans of this particular game, the real value here is in introducing us to the reverse engineering work on those Nintendo servers. We learn about their various foibles over several generations of console, and perhaps most importantly we learn something of their inner workings.

Usually when a game server is turned off it’s because the platform it supports is so ancient as to have hardly any users. This time-limited game on an up-to-date platform is unusual then, but since it was made available to subscribers to Nintendo’s online service for free it’s less of a surprise. Certainly not in the same class as the loss of servers for an entire platform.

Thanks [Digiaap] for the tip.

Turning The Virtual Boy Into A Handheld Console

June 10, 2021 by 9 Comments

The Virtual Boy, Nintendo’s most infamous failure, was plagued by several issues. The most glaring problem was the red monochrome stereoscopic display technology which gave many users a headache after even a short time playing, but it’s sky-high price and extremely limited library of games kept many prospective buyers at bay as well. There was also the issue of portability: unlike the Game Boy it was named after, the Virtual Boy barely qualified as a portable system due to the fact it needed to be set up on a table to use.

But now, thanks to the tireless efforts of [Shank], at least a few of those issues have been resolved. He’s built the world’s first truly portable Virtual Boy, which swaps the system’s troubled 3D display for a modern IPS LCD panel. The custom handheld, designed to merge the Virtual Boy’s unique aesthetic with the iconic styling of the Game Boy Advance, looks like it came from some alternate timeline where Nintendo decided to produce a cheaper and less cumbersome version of the system rather than abandoning it.

While the work [Shank] has put into the project is unquestionably impressive, it should be said that it took the efforts of several talented hackers to create the handheld Virtual Boy. The key component that made the modification possible in the first place is the VirtualTap by [Furrtek], which not only provides the VGA output that’s driving the LCD panel, but fools the system’s motherboard into believing the servo-actuated stereoscopic display is still connected and active.

It’s also using the open source power management board that [GMan] originally developed for his own portable N64, [Bassline] chipped in to cast the custom buttons and D-pad in translucent resin, and [Mitch 3D] put an untold number of hours into printing and reprinting the system’s multicolored enclosure until it came out just right.

All the little details of the final system, which [Shank] calls the Real Boy, put this project into a league of its own. Special combinations of button presses allows the user to change the color of the display, should you get sick of the infamous red-tint. The buttons also have RGB LEDs behind them that correspond with the color scheme of the display itself, for that extra bit of gamer cred. He even made sure to include the system’s original link port, despite the fact that no officially released game ever made use of it.

Our first run in with [Shank] was when he demoed a portable Wii built into a mint tin. It made for a pretty pitiful gaming experience, but the project demonstrated his dedication to seeing a project through to the end. Watching his skills improve over the last few years has been inspiring, and we can’t wait to see what he comes up with next.

Nintendo DS Transformed Into Gameboy Macro

June 8, 2021 by 7 Comments

Nintendo’s Game Boy line were the world’s most popular handheld gaming systems, but did have their drawbacks. Most notably, the Game Boy didn’t receive a backlit color LCD until the Game Boy Advance SP launched in 2003. Of course, you can always build your own Game Boy that rectifies this and other shortcomings, and that’s what [JoshuaGuess] did with this Gameboy Macro build.

The build ends up like a bigger version of the Game Boy Micro, the final release in the Game Boy line.

The build is based around a Nintendo DS Lite, one of Nintendo’s later handhelds featuring dual screens. In this build, the top screen is removed and discarded entirely. The motherboard is then hacked with a resistor on some test points to allow it to still boot with the top missing. The shell of the bottom half is then cleverly modified with epoxy clay and paint in order to hide the original hinge and give a clean finished aesthetic.

The final result is essentially a larger version of the Game Boy Micro, the final handheld in the Game Boy line. It also has the benefit of a bigger, brighter screen compared to virtually any Game Boy ever made. The only thing to note is that the DS hardware can only play Game Boy Advance games, not the earlier 8-bit titles.

It’s a fun build, and one that goes to show you don’t have to throw a Raspberry Pi in everything to have a good time. That can be fun too, though. If you end up building the Game Boy Nano or Game Boy Giga, please let us know. Be sure to include measurements to indicate how it’s scaled in SI units relative to the Game Boy Micro itself.

What NES Development Looks Like On The Apple II

May 20, 2021 by 29 Comments

These days, if you want to code a game for the original Nintendo Entertainment System, it’s about as easy as downloading an assembler, firing up Notepad, and running the ROMs you cook up in any one of a variety of emulators. In the 1980s none of those things existed, and the process was a little more complicated – as demonstrated by [Tyler Barnes] in the video embedded below.

[Tyler] has put together a 40-minute guide on what it takes to get to “Hello World” – or more accurately, a simple pink screen – on the NES, using period-correct hardware. He starts the process by formatting some floppy disks and whipping up some basic assembly code on an Apple IIe, which gets run through the Merlin assembler for the 6502. It’s particularly convenient as the Apple II line and the NES both run the same CPU. From there it’s a case of using a standalone EPROM programmer to verify some appropriately-datecoded chips are empty, before programming them in a special add-on card for the Apple II. From there, the EPROMs are loaded into a cart custom modified with chip sockets, where it can be inserted into a NES for testing.

It’s a tedious process, with just the programming side of things taking on the order of ten to twenty minutes with a few fiddly steps along the way. While there are likely some efficiency gains to be had that were used by studios back in the day, it remains clear that development in this era was a much slower process.

Of course, if you prefer your Nintendo homebrew a couple generations hence, consider getting stuck in on the Nintendo 64. Video after the break.

Pocket Sized Wii Sets The Bar For Portable Builds

May 7, 2021 by 4 Comments

Over the last few years we’ve seen several projects that convert Nintendo’s Wii into a handheld console by way of a “trimming”, wherein the system’s motherboard is literally cut down to a fraction of its original size. This is made possible due to the fact that the majority of the console’s critical components were physically arranged in a tight grouping on the PCB. While it might not be the smallest one we’ve ever seen, the Wii SPii by [StonedEdge] is certainly in the running for the most technically impressive.

It took [StonedEdge] the better part of a year to go from the first early 3D printed case concepts to the fully functional device, but we’d say it was certainly time well spent. The general look of the portable is strongly inspired by Nintendo’s own GameBoy Advance SP, albeit with additional buttons and control sticks. In terms of software, the system is not only able to run Wii and Gamecube game ISOs stored on its SD card, but also several decades worth of classic titles through the various console emulators available for the system.

The Wii SPii makes use of a particularly difficult variation of the Wii miniaturization concept known as the OMEGA trim, and is supported by a custom PCB that’s responsible for things like power management and audio output. As it was never designed to be particularly energy efficient, the trimmed Wii motherboard will deplete the system’s dual 18650 cells in about two and a half hours, but at least you’ll be able to get charged back up quickly thanks to USB-C PD support. All of the hardware just fits inside the custom designed case, which was CNC milled from acrylic and then sandblasted to achieve that gorgeous frosted look.

[StonedEdge] says the Wii SPii was inspired by the work of accomplished smallerizer [GMan], and even uses some of the open source code he developed for the audio and power management systems. In fact, given its lengthy list of acknowledgements, this project could even be considered something of a community affair. Just a few years after we marveled at a functional Wii being crammed into an Altoids tin, it’s truly inspiring to see what this dedicated group of console modders has been able to accomplish by working together.

Exploring The World Of Nintendo 3DS Homebrew

April 28, 2021 by 20 Comments

When Nintendo officially ended production of the 3DS in September 2020, it wasn’t exactly a surprise. For one thing, some variation of the handheld system had been on the market since 2011. Which is not to say the product line had become stagnant: the system received a considerable mid-generation refresh, and there was even a more affordable variant introduced that dropped the eponymous stereoscopic 3D effect, but nearly a decade is still a fairly long life in the gaming industry. Of course Nintendo’s focus on the Switch, a hybrid device that blurs the line between console and handheld games, undoubtedly played a part in the decision to retire what could effectively be seen as a competing product.

While putting the 3DS out to pasture might have been the logical business move, a quick check on eBay seems to tell a different story. Whether it’s COVID keeping people indoors and increasing the demand for at-home entertainment, or the incredible library of classic and modern games the system has access to, the fact is that a used 3DS in good condition is worth more today than it was when it was brand new on the shelf this time last year.

I’ve certainly made more expensive mistakes.

In short, this was the worst possible time for me to decide that I finally wanted to buy a 3DS. Then one day I noticed the average price for a Japanese model was far lower than that of its American counterpart. I knew the hardware was identical, but could the firmware be changed?

An evening’s worth of research told me the swap was indeed possible, but inadvisable due to the difficulty and potential for unexpected behavior. Of course, that’s never stopped me before.

So after waiting the better part of a month for my mint condition 3DS to arrive from the land of the rising sun, I set out to explore the wide and wonderful world of Nintendo 3DS hacking.

Giant Nintendo Switch Is Actually Playable

April 5, 2021 by 6 Comments

The Nintendo Switch has been a hugely successful console for the century-old former playing card manufacturer. At least part of that success has come from its portability, of which [Michael Pick] has probably lost a bit with his 65-pound giant Nintendo Switch built for St. Jude’s Children’s Hospital. (Video, embedded below.) What he’s lost in portability has been more than made up in coolness-factor, though, and we’re sure the kids will appreciate that they can still play the monster gaming machine.

From its plywood body to the 3D-printed buttons, the supersized build looks solid. Docked inside the left Joy-Con is the actual console powering its big brother. Perhaps the biggest surprise, however, is that tiny (well, normal-sized) Joy-Cons are also hidden inside. These are manipulated via servos for the buttons and a direct pass-through setup for the joysticks to control games on the Switch.

While the Joy-Cons are unmodified and completely removable, [Michael] does recognize this isn’t necessarily the ideal solution. But he was certain it was a hack he could make work in the time he had, so he went for it. He’s looked into the controller emulation possible with Teensys and would probably use that solution for any giant Switch projects in the future. Of course, with this build, players can still pair regular Joy-Cons and pro controllers for more practical gaming.

Most Nintendo mods we see attempt to make the console smaller, not larger, so this is an eye-catching change of pace. Unfortunately, we don’t get to see the colossal console in action after it was installed, only some stills of hospital staff wheeling it in the front doors. But we can imagine that the children’s smiles are at least as big as ours were when we saw it.
