Play Giant Tetris On Second-Floor Window

May 28, 2024 by 11 Comments

Sometimes it seems like ideas for projects spring out of nothingness from a serendipitous set of circumstances. [Maarten] found himself in just such a situation, with a combination of his existing Tetris novelty lamp and an awkwardly-sized window on a second-floor apartment, he was gifted with the perfect platform for a giant playable Tetris game built into that window.

To make the giant Tetris game easily playable by people walking by on the street, [Maarten] is building as much of this as possible in the browser. Starting with the controller, he designed a NES-inspired controller in JavaScript that can be used on anything with a touch screen. A simulator display was also built in the browser so he could verify that everything worked without needing the giant display at first. From there it was on to building the actual window-sized Tetris display which is constructed from addressable LEDs arranged in an array that matches the size of the original game.

There were some issues to iron out, as would be expected for a project with this much complexity, but the main thorn in [Maarten]’s side was getting his controller to work in Safari on iPhones. That seems to be mostly settled and there were some other gameplay issues to solve, but the unit is now working in his window and ready to be played by any passers-by, accessed by a conveniently-located QR code. Tetris has been around long enough that there are plenty of unique takes on the game, like this project from 2011 that uses Dance Dance Revolution pads for controllers.

Adafruit Badges Turned Electronic Invitations

May 28, 2024 by 8 Comments

Despite what you might have heard, even the most devout Hackaday readers may eventually find themselves getting married. Should you ever find yourself in a situation where you need to send out invitations for your big day, or any other major celebration for that matter, you could do worse than follow the example [Mokas] and their partner set with these memorable electronic wedding invitations.

Inspired by the electronic badges distributed at hacker cons, [Mokas] decided to use Adafruit’ EdgeBadge and PyBadge devices to create a similar interactive keepsake that would be a bit more exciting than a piece of paper. While it would have been enough to have the wedding information pop up on the screen when they were turned on, the final invites actually boot into a retro-style game where you walk around talking to characters to uncover information about the event and the venue.

The game was created in Microsoft MakeCode Arcade, with a sprinkling of original and commissioned sprites. Early versions of the game ended up being a bit much for the Adafruit badge’s to handle, but after doing a bit of research on creating games for computationally-constrained platforms, [Mokas] was able to optimize the performance. For those that didn’t get a physical invite (no doubt ours was simply lost in the mail), you can play the whole thing right in your browser.

It’s a very clever idea, and while using custom hardware would have allowed for a more bespoke package, we can’t blame [Mokas] for wanting to keep this one simple. Getting everything ready for your wedding is already enough stress — it’s hardly the time to spin up a new board.

For a similar reasons, another Adafruit offering was selected to power the couple’s e-ink baby development display.

How A DOS Format Blunder Revealed Some Priceless Source Code

May 25, 2024 by 14 Comments

As those of us who worked in the consumer software world back when physical media was king can attest, when a master disc has been sent for duplication and distribution there is no turning back from whatever code is in the hands of thousands of users. Usually such worries were confined to bugs or inadvertently sending out pre-release software versions, but [Lance Ewing] is here with the story of how Sierra On-Line once inadvertently released most of the source code for their game engine.

If you have some 720k floppy disk versions of the 1988 game Space Quest II, the first disk in the set appears to have nothing out of the ordinary, but a closer look reveals that the free space on the disk reported by DOS is greater than its used space. Diving in to the disk block contents with a hex editor reveals that many of the unused blocks in fact contain C code, and some further detective work allows the recovery of a not-quite complete set of source files for the company’s AGI, or adventure game interpreter. They had been left behind when the original master disk had been emptied by deleting them, rather than by formatting it afresh.

In commercial terms this would in 1988 have been something of a disaster for Sierra had it been discovered at the time, because it was the cornerstone of their success. As it was we’re told the code sat peacefully undetected until 2016, since when it has proved invaluable to those interested in computer game archaeology. Or did it? We’ll never know if a sharp-eyed competitor snagged it, and kept quiet.

Of course, these days, there are game engines that are open source. Some of them are very modern. Others… not so much.

It has the FM station 88.9 in large letters in the middle of the display and "Ice Cream (Pay Phone) by Black Pumas" displayed in a box below. A volume indicator is on the left side of the tuner numbers and various status icons are along the top of the screen.

Orange FM Brings Radio To The GameBoy

May 23, 2024 by 12 Comments

We’ve all been there. You left your Walkman at home and only have your trusty Game Boy. You want to take a break and just listen to some tunes. What to do? [orangeglo] has the answer now with the Orange FM cartridge.

This prototype cart features an onboard antenna or can also use the 3.5 mm headphone/antenna port on the cartridge to boost reception with either a dedicated antenna or a set of headphones. Frequencies supported are 64 – 108 Mhz, and spacing can be set for 100 or 200 kHz to accomodate most FM broadcasts setups around the world.

Older Game Boys can support audio through the device itself, but Advances will need to use the audio port on the cartridge. The Super Game Boy can pipe audio to your TV though, which seems like a delightfully Rube Goldberg-ian way to listen to the radio. Did we mention it also supports RDS, so you’ll know what that catchy tune is? Try that FM Walkman!

Can’t decide between this and your other carts? Try this revolving multi-cart solution. Have a Game Boy that needs some restoration? If it’s due to electrolyte damage, maybe start here?

Static Recompilation Brings New Life To N64 Games

May 21, 2024 by 19 Comments

Over the past few years a number of teams have been putting a lot of effort into taking beloved Nintendo 64 games, decompiling them, and lovingly crafting them into highly portable C code. This allows for these games to not only run natively on PCs, but also for improvements to be made to the rendering engine and other components.

Yet this artisan approach to porting these games means a massive time investment, something which static binary translation (static recompilation) may conceivably speed up. Enter the N64: Recompiled project, which provides a binary translation tool to ease the translation of the N64’s binaries into C code.

This is effectively quite similar to what an emulator does in real-time, just with the goal of creating a permanent copy of the translated instructions. After this static binary translation, the C code can be compiled again, but as noted by the project’s documentation, a suitable runtime is needed to get a functional game. An example of this is the Zelda 64: Recompiled project, which uses the N64: Recompiled project at its core, while providing the necessary scaffolding and wrappers to create a working copy of The Legend of Zelda: Majora’s Mask as output.

In the video below, [Modern Vintage Gamer] takes the software for a test drive and comes away very excited about the potential it has to completely change the state of N64 emulation. To be clear, this isn’t a one-button-press solution — it still requires capable developers to roll up their sleeves and get the plumbing in. It’s going to take some time before you favorite game is supported, but the idea of breathing new life into some of the best games from the 1990s and early 2000s certainly has us eager to see where this technology goes

Hack Your Own Adventure Story With Yarn Spinner

May 18, 2024 by 8 Comments

We are big fans of programmed texts for education. You know, the kind where you answer a question and go to a new page based on your answer. But they can also be entertaining “choose your own adventure” stories. You might say, “You are standing in front of an oak door, two meters high, with an iron handle. Do you a) open it? b) knock on it? c) ignore it?” Then, based on your answer, you go to a different part of the story. These are tough to write, but you can get some help using Yarn Spinner and the Yarn scripting language.

The original purpose of Yarn is to produce conversations for games. There’s a tutorial for that. The difference is to produce a book, you get a choose your own adventure PDF at the end. For the tutorial, you can try to read the text on the left-hand side of the editor or just press Test (at the top) and let it “read” the tutorial to you, which is a little more fluid.

Pump It Up Gets Homebrew GBA Port That Rocks

May 16, 2024 by 3 Comments

Pump It Up is a popular music video game that hails from South Korea. It’s similar in vibe to Dance Dance Revolution and In The Groove, but it has an extra arrow panel to make life harder. [Rodrigo Alfonso] loved it so much, he ported it to the Game Boy Advance.

The port looks fantastic, with all the fast-moving arrows and lovely sprite-based graphics you could dream of. But more than that, [Rodrigo’s] port is very fully featured. It doesn’t rely on tracked or sampled music, instead using actual GSM audio files for the songs.

It can also accept input from a PS/2 keyboard, and you can even do multiplayer over the GBA’s Wireless Adapter. What’s even cooler is that some of the game’s neat features have been broken out into separate libraries so other developers can use them. If you need a Serial Port library for the GBA, or a way to read the SD card on flash carts, [Rodrigo] has put the code on GitHub.

As you might have guessed, this isn’t the first time [Rodrigo] has pushed the limits on what Nintendo’s 32-bit handheld can do.
