Hacklet 22 – Retro Console Projects

Everyone loves arcade games, and it didn’t take long for designers to figure out that people would love to take the fun home. The home gaming console market has been around for decades. Through the early days of battery-powered pong style consoles through Atari and the video game crash of the early 80’s, to the late 8 and 16 bit era spearheaded by The Nintendo Entertainment System and The Sega Master System and beyond, consoles have become a staple of the hacker home. This week’s Hacklet features some of the best retro console projects from Hackaday.io!

52001We start with [ThunderSqueak] saving the world with her Atari 5200 Custom Controller Build. For those who don’t know, the Atari 5200 “Super System” was an 8 bit system ahead of its time. The 5200 was also saddled with on of the worst controller designs ever. The buttons would stop responding after a few hours of game play. With 17 buttons, (including a full number pad), that was a pretty major design flaw! [ThunderSqueak] hacked a cheap commercial fighting game stick to make it work with the 5200. 12 individual buttons were wired in a matrix to replace the telephone style keys on the original 5200 controller. Atari’s non-centering analog stick was converted over to a standard 4 switch arcade style stick. [ThunderSqueak] did leave the original pots accessible in the bottom of the enclosure for centering adjustments. Many 5200 games work great with the new setup.

 

snes[DackR] is bringing back the glory days of Nintendo with Super Famicade, a homebrew 4 SNES arcade system inspired by Nintendo’s Super System. Nintendo’s original Super System played several customized versions of games which were available on the Super Nintendo Entertainment System (SNES). [DackR] is building his own with parts from four SNES consoles. He’s also adding a few features, like a touch screen, video overlay, and enhanced RGB.

He’s going to add custom memory monitoring hardware, which will allow him to check how many lives a player has left and handle coin operation, all without the original Super System Hardware. If you’re curious what the original Super Systems looked like, check out Hackaday’s Tokyo Speedrun video.You might just catch a glimpse of one!

rgb[Bentendo64] is improving on the past with RGB For ‘Murica. European systems have enjoyed the higher quality afforded by separate red, green and blue video lines for decades. North American gamers, however were stuck in the composite or S-Video realm until shortly before the HDTV age. [Bentendo64] had an old hotel CRT based monitor, and decided to hack an RGB input. After opening up the back of the set, he removed the yolk board and added direct inputs to the video amplifiers. We’re not sure if this mod will work with every CRT, but it can’t hurt to try! Just be sure to discharge those high voltage capacitors before wrenching on these old video systems. Even if a set has been unplugged for days, the caps can give a seriously painful (and dangerous) shock!

snes2[Ingo S] is also working to improve the SNES with SNES AmbiPak, a mod which brings ambient lighting and “rumble pack” controller feedback to the vintage Super Nintendo. [Ingo S] used the popular SNES9X emulator to figure out where game data is stored while the SNES is running. His proof of concept was the original F-ZERO SNES game. [Ingo S] found that Every time the player’s car hits the wall, the system would perform a write on address 3E:0C23. All he would need to do is monitor that address on the real hardware, and rumble the controller on a write. The real hardware proved to be a bit harder to work with though. Even these “slow” vintage systems clock their ram at around 3MHz, way too fast for an Arduino to catch a bus access.  [Ingo S] is solving that problem with a Xilinx XC9572 Complex Programmable Logic Device (CPLD). CPLDs can be thought of as little brothers to Field Programmable Gate Arras (FPGAs). Even though they generally have less “room” for logic inside, CPLDs run plenty fast for decoding memory addresses.  With this change, [Ingo S] is back on track to building his SNES rumble pack!

It feels like we just got started – but we’re already out of space for this week’s Hacklet! As always, see you next week. Same hack time, same hack channel, bringing you the best of Hackaday.io!

  1. You guys probably already know this, but the image on the ‘blog’ list looks like a bunch of blue pixels, and when you click the article you can actually see its the ‘Hacklet #22’ banner style image, seems that on the blog it zooms in to it for some reason, luckily that banner had a nice bit of blue in the middle, might look a bit odd if there were some image or text there (major pixelation)

  2. What would work best on the 5200 controllers is modifying the bottom housing to take four PCBs with SMT microswitches, positioned so that the original buttons can press them.

    I’ve some ideas for a modification to make the sticks self centering but I’d need a controller to work with.

    I used to have a 5200 and spent quite a bit of time getting the controllers to work. Had to solder pieces of wire across broken traces and also had to try several different glues to find something to stick pieces of aluminum foil onto the undersides of the fire buttons where the carbon coating had worn off.

    1. I fixed the bad keys on my remote by using aluminium foil from a blister pack. The foil has a plastic cover, but a scrap with a blade would remove enough, but still leave some insulation so it doesn’t short normally. I used a hole punch to cut it and tape that on top of the PCB on one side making a flap. That works much better than trying to glue/paint stuff on silicon.

    2. I did play with the idea of redesigning a pcb to fit into the controller housings that I cannibalized for the above project. Another silly thought was simply adding springs to make the joysticks self centering. :)

      Maybe after I finish a few of my other projects first ^^
