TVout Library Brings Cardboard Arcade To Life

August 12, 2022 by Orlando Hoilett 12 Comments

Recycling old CRTs is a true Hackaday tradition, and [Rob’s] mini arcade is sure to grab your attention.

First of all, you’ll probably appreciate [Rob] circumventing the supply shortage by getting all his components from recycled material. That’s probably the only way to get anything these days. He salvaged a small CRT from an old-school video intercom system and snagged the buttons, speakers, and switches from other unused devices laying around. Not all is lost, however, as [Rob] was able to purchase an Arduino Nano and a few resistors online. So maybe things are turning around in that category, who knows?

You’ll probably also appreciate how remarkably simple this hack is. No need for a Raspberry Pi as your standard 8-bit microcontroller will do the trick. And, fortunately, [Rob] found a nice library to help him generate the composite video signal, doing most of the work for him. All that was left to do was to build the arcade cabinet. Recreating the classic design was a pretty easy step, but you might opt for something a little nicer than cardboard though. But, hey, if it does the trick, then why not?

Cool project, [Rob]! We’re definitely happy to add this project to our retro collection here at Hackaday.

Tiny Arcade Uses Tiny CRT

July 27, 2022 by Bryan Cockfield 16 Comments

Restoring vintage electronics is a difficult hobby to tackle. Even the most practical builds often have to use some form of modern technology to work properly, or many different versions of the machine need to be disassembled to get a single working version. Either way, in the end someone will be deeply hurt by the destruction of anything antique, except perhaps with [Marco]’s recent tiny arcade with a unique CRT display.

The CRT is a now-obsolete technology, but Arcade and MAME purists often seek them out because of the rounded screen and vintage feel these devices have when compared to modern LCD or LED displays. For a build this small, though, [Marco] couldn’t just use parts from an old TV set as there wouldn’t be clearance in the back of the cabinet. An outdated video conferencing system turned out to have just the part he needed, though. It has a CRT mounted perpendicularly to a curved screen in order to reduce the depth needed dramatically.

The final build uses a tiny Namco system meant to plug into the RCA jack on a standard TV, but put in a custom case that makes it look like an antique video game cabinet. It’s an interesting build that doesn’t destroy any valuable antique electronics, while still maintaining a classic arcade feel. If you’re building a larger arcade cabinet which will still satisfy the purists out there, make sure you’re using a CRT with the right kind of control system.

Reverse-Engineering Forgotten Konami Arcade Hardware

June 28, 2022 by Bryan Cockfield 4 Comments

When fully-3D video games started arriving in the early 90s, some companies were more prepared for the change than others. Indeed, it would take nearly a decade of experimentation before 3D virtual spaces felt natural. Even then, Konami seems to have shot themselves in the foot at the beginning of this era with their first foray into 3D arcade games. [Mog] shows us the ins-and-outs of these platforms while trying to bring them back to life via MAME.

These arcade machines were among the first available with fully-3D environments, but compared to offerings from other companies are curiously underpowered, even for the time. They include only a single digital signal processor which is tasked with calculating all of the scene geometry while competing machines would use multiple DSP chips to do the same job. As a result the resolution and frame rate are very low. Nonetheless, [Mog] set out to get it working in MAME.

To accomplish this task, [Mog] turned to a set of development tools provided to developers for Konami in the early 90s which would emulate the system on the PCs of the time. It surprisingly still worked on Windows 10 with minor tweaking, and with some other tools provided over the decades of others working on MAME these old Konami machines have some new life with this emulator support.

Not everything works perfectly, but [Mog] reports that most of the bugs and other issues were recently worked out or are being actively worked on by other experts in the field. If you remember these games from the arcade era of the 80s and early 90s, it might be time to grab an old CRT and fire this one up again.

DOOM Ported To Sega Naomi Arcade Hardware

June 17, 2022 by Lewin Day 8 Comments

Porting DOOM to new hardware and software platforms is a fun pastime for many in the hacker scene. [DragonMinded] noticed that nobody had ported the game to the Sega Naomi arcade hardware, and set about doing so herself.

The port builds on work by [Kristoffer Andersen] who built a framebuffer port of DOOM previously. It’s available pre-compiled, complete with the shareware WAD for those eager to load it up on their own Naomi arcade cabinets.

Unlike some limited ports that only give the appearance of a functional version of DOOM, this port is remarkably complete. Loading, saving, and options menus are all present and accounted for, as well as directional sound and even WAD auto-discovery. With that said, there’s only 32 KB of space for save games on the Naomi hardware, so keep that in mind if you find yourself playing regularly.

We love a good DOOM port, whether it’s on an arcade machine, an old forgotten Apple OS, or even a UFI module.

Will MiSTer Fool You Into Learning FPGAs?

May 9, 2022 by Elliot Williams 45 Comments

What’s the killer app for FPGAs? For some people, the allure is the ultra-high data throughput for parallelizable tasks, which can enable some pretty gnarly projects. But what if you’re just starting out? How about 1980s style video games?

The MiSTer FPGA project created a bit of FPGA hardware that makes it easy to build essentially any old school video game or computer platform. That’s a massive clean slate. Of course, you can simply download someone else’s Atari ST or Commodore 64 setup and load it up, but if you want to learn FPGAs while recreating old-school video game machines, you’re going to want to get your hands dirty.

[Mister Retro Wolf] started up a video series last winter (trailer embedded below) where he’s embarked on a project to recreate a classic video game machine from the ground up using the MiSTer FPGA platform. In particular, he’s going to recreate the Namco Tank Battalion arcade game, from the schematics, in Verilog.

This is literally building a 6502-based video game machine from scratch (in gateware), so if you’re interested in retrocomputing or FPGAs, you’ll have something to learn here. He’s gotten through the CPU, screen, tilemap graphics, and memory so far, but it’s not done yet. To follow along, get yourself some hardware and you can probably catch up.

We’ve covered the MiSTer FPGA project before, of course, because we think it’s cool. And if a video game arcade machine is going to be your gateway drug into the seedy world of programmable gates, then so be it.

Retrotechtacular: Raw Video From Inside A 1980s Arcade

February 14, 2022 by Drew Littrell 42 Comments

It was just this year that Sega left the arcade business for good. A company synonymous with coin-op games for over a half century completely walked away from selling experiences you can only get on location. No more Outrun or Virtua Fighter machines, because arcades these days tend to resemble The House of the Dead. Arcades still exist to a degree, it’s just that headlines like that serve only as a reminder of an era gone by. Which is what makes raw footage like the video [Jon] posted of an Aladdin’s Castle arcade from the 1980s so compelling.

The raw VHS footage starts with a sweep around the location’s pinball machines and arcade cabinets. There’s an extended shot of a rare TX-1 tri-monitor sitdown cabinet. The racing game was the first of its kind to feature force feedback in the steering wheel, so it’s no wonder it received the focus. The arcade’s lighting tech was also a point of pride as it allowed for programmable lighting cues. A far cry from the flickering fluorescent tubes no doubt in use elsewhere. Eventually the employee filming takes us to the back room where it the owner has made it abundantly clear that they are not a fan of Mondays, judging by the amount of Garfield merchandise.

Bally’s Aladdin’s Castle was a chain of arcades and had nearly 400 locations across the US at its height in the mid 1980s (at least according to their brochure seen above). Those neon red letters were a mainstay of American shopping malls throughout the decade. Namco, the Pac-Man people, acquired Aladdin’s Castle in 1993 and the brand faded away soon after. Although there is a lone location in Quincy, IL that is still open for business today.

N-Gage Controller Uses All The Buttons

November 25, 2021 by Bryan Cockfield 6 Comments

If there’s anything you can guarantee about a video game system, it’s that in 20 years after one suffers a commercial failure there will be a tiny yet rabid group of enthusiasts obsessed with that system. It’s true for the Virtual Boy, the Atari Jaguar, and of course, the Nokia N-Gage. For those not familiar, this was a quirky competitor of the Game Boy Advance that was also a cell phone. And for that reason it had more buttons than a four-player arcade cabinet, which has led to things like this custom controller.

Most N-Gage gaming these days takes place on emulators, this build is specifically built for the emulator experience. The original system had so many buttons that it’s difficult to get even a standard 102-key keyboard mapped comfortably to it, so something custom is almost necessary. [Lvaneede], the creator of this project, took some parts from an existing arcade cabinet he had and 3D printed the case in order to craft this custom controller. The buttons he chose are a little stiff for his liking, but it’s much better than using a keyboard.

In the video below, [Lvaneede] demonstrates it with a few of the N-Gage’s games. It seems to hold up pretty well. With backing from Sony and Sega, it’s a shame that these gaming platforms weren’t a bigger hit than they were, but there are plenty of people around with original hardware who are still patching and repairing them so they can still play some of these unique games.

Thanks to [Michael] for the tip!
