GTA V Mod Shows (And Cheats) Those Stunt Jump Hoops

August 21, 2020 by Sven Gregori No comments

While the recent announcement of Grand Theft Auto V for the upcoming next-generation game consoles was a disappointment for those fervently waiting for a successor in the infamous video game series, it shows that after almost seven years of its initial release, the epic title is still going strong — and rightfully so. But a game as varied and complex as GTA V isn’t without some quirks, especially if you’re going for 100% completeness.

The stunt jumps seem a particular pesky nut to crack here, so [Anthony Som] made it his mission to shed some light on what qualifies as a successful jump by reverse engineering the system and writing both a mod for displaying the landing zone and a cheat to instant success.

If you’re not familiar with the game, its vast open world map features a variety of side quests, one of them being stunt jumps, where certain locations allow you to launch the vehicle you’re driving into the air in hopes to land on an adjacent road or area — whether to evade the people chasing you, or just for fun. There’s no telling how to actually succeed though, the game just tells you if you did or not afterwards, causing some degree of frustration. As an avid speedrunner (as in finishing a game in the shortest possible time), [Anthony] was looking for a way to increase the success rate for those stunt jumps, and decided to dig into the code to find out how to get there. Of course, being a proprietary game, he had to resort to reverse engineering and utilizing GTA’s vivid modding scene to do so.

His initial outcome was a mod that displays the launch and landing area as rectangles inside the game itself, which was a great help. But well, after already getting that far, [Anthony] figured he might as well continue and add a cheat mode to teleport the car right inside that expected landing area and be done with second-guessing his attempts once and for all.

If you’re curious about modding GTA yourself, his write-up has a few good pointers for that, and of course features some real examples of it. Whether this is a good idea for the self-driving AI that uses GTA as learning environment is probably a different story though.

Building The Scoreboard Of Your Imagination

August 19, 2020 by Mike Szczys 5 Comments

It might seem like electronic games and tabletop games are somewhat at odds. But there are always places where the lines are cleverly blurred as with this stat tracker beautifully constructed from a sandwich of circuit boards.

The nature of role playing games is one of deep imagination, putting yourself in the shoes of the player your are building though out a campaign. But of course the game board and pieces are there to keep track of all the data that your imagination just can’t. This can be done with a character card and some markers, a pad of paper, or a spreadsheet on your laptop. But to keep his mind in the world of Hyper Light Drifter, [Albert Phan] built this stat tracker that lives up to the aesthetic of the game.

The stackup of three PCBs does a brilliant job here, using cutouts on either end of the faceplate as a flexible tab that you press to actuate the surface mount button on the bottom PCB. The third PCB act as a spacer, not just for the six low-profile buttons, but also for the 40 LEDs that display status. That spacer has holes cut out for each light, providing isolation, with the FR4 substrate of the top plate acting as a diffuser.

It looks spectacular, it saves state between uses, and can be recharged via USB. But what’s that you say? You don’t play Hyper Light Drifter? Just respin the top PCB (and we suppose you’d need to tweak firmware as well) and you can swap it out for your game of choice.

Miniature Star Wars Arcade Lets You Blow Up The Death Star On The Go

August 12, 2020 by Tom Nardi 10 Comments

If you have fond childhood memories of afternoons spent at the local arcade, then you’ve had the occasional daydream about tracking down one of those old cabinets and putting it in the living room. But the size, cost, and rarity of these machines makes actually owning one impractical for most people.

While this fully functional 1/4th scale replica of the classic Star Wars arcade game created by [Jamie McShan] might not be a perfect replacement for the original, there’s no denying it would be easier to fit through your front door. Nearly every aspect of the iconic 1983 machine has been carefully recreated, right down to a working coin slot that accepts miniature quarters. Frankly, the build would have been impressive enough had he only put in half the detail work, but we certainly aren’t complaining that he went the extra mile.

[Jamie] leaned heavily on resin 3D printed parts for this build, and for good reason. It’s hard to imagine how he could have produced some of the tiny working parts for his cabinet using traditional manufacturing techniques. The game’s signature control yoke and the coin acceptor mechanism are really incredible feats of miniaturization, and a testament to what’s possible at the DIY level with relatively affordable tools.

The cabinet itself is cut from MDF, using plans appropriately scaled down from the real thing. Inside you’ll find a Raspberry Pi 3 Model A+ running RetroPie attached directly to the back of a 4.3 inch LCD with integrated amplified speakers. [Jamie] is using an Arduino to handle interfacing with the optical coin detector and controls, which communicates with the Pi over USB HID. He’s even added in a pair of 3,000 mAh LiPo battery packs and a dedicated charge controller so you can blow up the Death Star on the go.

Still don’t think you can fit one in your apartment? Not to worry, back in 2012 we actually saw somebody recreate this same cabinet in just 1/6th scale.

Scratch Built Subnautica Sub Explores The Pool

August 6, 2020 by Tom Nardi 6 Comments

In Subnautica, players explore an alien underwater landscape with the help of a number of futuristic tools and vehicles. [Robert Cook] found himself particularly enamored with the large submarine you unlock towards the later parts of the game, so much so that he decided to build his own real-life version.

Even though the RC version of the Cyclops [Robert] has designed is only big enough to explore swimming pool sized alien landscapes, it’s by no means a simple build. In fact, the sub’s internal watertight compartment holds an impressive array of electronics and systems that are arguably overkill for what’s essentially a toy. Not that we’re complaining, of course.

Beyond the electronics and a few key components, almost every part of the RC Cyclops has been 3D printed. From the bulkheads that cap off the internal watertight acrylic tube to the hull itself, there’s a lot of plastic aboard this ship. Which might explain why it takes nearly two kilograms of lead weight to get the sub close to neutral buoyancy. From there, a clever ballast tank arrangement made from a syringe and peristaltic pump allow the vehicle to dive and surface on command.

[Robert] is in the process of releasing the STL files for all the submarine’s 3D printed components, and has done an excellent job of documenting the roughly four months he’s spent working on the project in a series of videos on his YouTube channel. The videos contain a wealth of fascinating tips and tricks regarding DIY submersible vehicles, such as selecting the proper radio frequencies for maximum penetration through water and counteracting the permeability of 3D printed parts with a generous coating of epoxy.

Modern RC hardware makes it easier than ever to cobble together a “submarine”, but there’s still something to be said for a project that takes the long way around and actually implements features like a functioning ballast system.

Retro Game Bow Tie

August 4, 2020 by Orlando Hoilett 4 Comments

[Greg] loves hacking his bow ties. Back in high school, he added some bright RGB LEDs to the bow tie he wore to prom and even won the male best-dressed award. Recently he decided to try another bow tie hack, this time giving his tie some retro arcade game feels.

He decided to use an ATtiny85 and to experiment doing some more lower-level programming to refresh his skills. He wrote all his libraries from scratch which really helped him learn a lot about the ATtiny in the process. This also helped him make sure his code was as efficient as possible since he had quite a bit of memory constraints using the ATtiny85 (only 512 bytes of RAM).

He designed the body of the bow tie with wood. He fit all the electronics inside the body while allowing the ATtiny to protrude out of the body giving his bow tie some wanted hacker aesthetic. Of course, he needed to access the toggle switch to play the game, so he made a slot for that as well.

Nice addition to the electronics bow tie collection on Hackaday. Really aesthetic design if you ask us. And you know how much we love retro games.

Myst ‘Demake’ For The Apple II

July 30, 2020 by Maya Posch 12 Comments

Making certain games run on systems which were never designed to run such games (or any games at all) is a favorite hobby of some, with [deater] being no exception. His latest creation involves porting Myst to the Apple II, or ‘demake’ in his own words. This means taking a game that was released in 1993 for MacOS and later for Windows 3.1 and the original PlayStation, and creating a version that works on an 8-bit system from 1977.

Obviously the graphical fidelity has been turned down some compared to the 1990s version, but at this stage much of the game’s levels have been implemented. For anyone who has ever played the game before, much of the visuals will be instantly recognizable. According to [deater], the game should run on any Apple II/II+/IIe, with at least 48 kB of RAM, but 64 kB needed for sound effects. If a Mockingboard sound card is installed, it will even play the intro theme.

On the project page the (currently) three floppy disks can be downloaded, with the source available on Github. While one is there, one can also check out [deater]’s ‘Another World’ port to the Apple II which we covered last year.

RGB Minecraft Sign Isn’t Just For Looks

July 24, 2020 by Tom Nardi No comments

This laser cut and LED illuminated version of the Minecraft logo created by [Geeksmithing] looks good enough to occupy a place of honor on any gamer’s shelf. But it’s not just decoration: it can also notify you about your Minecraft’s server status and tell you when players are online by way of its addressable LEDs.

In the first half of the video after the break, [Geeksmithing] shows how the logo itself was built by cutting out pieces of white and black acrylic on his laser cutter. When stacked up together, it creates an impressive 3D effect but also isolates each letter. With carefully aligned rows of RGB LEDs behind the stack, each individual letter can be lit in its own color (or not at all) without the light bleeding into either side.

Once he had a way of lighting up each letter individually, it was just a matter of writing some code for the Raspberry Pi that can do something useful with them. Notifying him when the server goes down is easy enough, just blink them all red. But the code [Geeksmithing] came up with also associates each letter with one of the friends he plays with, and lights them up when they go online. So at a glance he can not only tell how many friends are already in the game, but which ones they are. Naturally this means the display can only show the status of nine friends…but hey, that’s more than we have anyway.

We’ve been seeing people connect the real world to Minecraft in weird and wonderful ways for years now, and it doesn’t seem like there’s any sign of things slowing down. While we recognize the game isn’t for everyone, but you’ve got to respect the incredible creativity it’s inspired in young and old players alike.
