Back then, I loved watching my young son happily pull off <a href=\"https:\/\/www.google.com\/search?kgmid=%2Fg%2F122b4b9m&amp;q=%E7%9E%AC%E7%8D%84%E6%AE%BA\">Raging Demon<\/a> command inputs\u2014it's still one of my favorite memories.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fast forward to recently: we picked up <a href=\"https:\/\/www.google.com\/search?kgmid=%2Fg%2F1yjg7x54d&amp;q=%E3%82%A6%E3%83%AB%E3%83%88%E3%83%A9%E3%82%B9%E3%83%88%E3%83%AA%E3%83%BC%E3%83%88%E3%83%95%E3%82%A1%E3%82%A4%E3%82%BF%E3%83%BCIV%EF%BC%88%E3%82%A6%E3%83%ABIV%EF%BC%89\">Ultra Street Fighter IV (USF4)<\/a> for another 500 yen, and our fighting game passion reignited instantly. I dusted off an old arcade stick (made by Sanwa Supply) that I had bought years ago at a Hard Off in Kurume for 1,500 yen and had sitting unused. When I hooked it up, it worked wonderfully! The clatter of joystick levers returned to our household.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I wanted to get SF6, intending to buy it on the upcoming Switch 2, but my son\u2014now a 6th grader who gathers all kinds of gaming news on YouTube\u2014came to me with some serious advice:<br>\"If you're playing fighting games, PC (Steam) is definitely better\u2014there's no frame drop or lag!\"<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Spurred on by his words, I impulsively bought the PC version of <a href=\"https:\/\/www.google.com\/search?kgmid=%2Fg%2F11sqhzkld6&amp;q=%E3%82%B9%E3%83%88%E3%83%AA%E3%83%BC%E3%83%88%E3%83%95%E3%82%A1%E3%82%A4%E3%82%BF%E3%83%BCVI%EF%BC%88%E3%82%B9%E3%83%886%EF%BC%89\">Street Fighter 6 (SF6)<\/a> Year 1 &amp; 2 Pack for about 5,000 yen.

This intense drive\u2014\"I want to play the latest game in the best environment, and on a modern leverless controller!\"\u2014became the driving force behind this scratch-build project.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Three Technical Challenges Undertaken in This Build Project<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In executing this custom build, this blog series will connect all the dots from the various testing and design concepts I previously shared individually, covering the following points:<\/p>\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Preliminary Modding of an Arcade Stick to Validate Construction Methods<a href=\"https:\/\/175.41.248.22\/games\/post-199-5838\/\" target=\"_blank\" rel=\"noreferrer noopener\">\"Pre-emptive Arcade Stick Modding\"<\/a><\/strong><br>To verify if the techniques I brainstormed for this leverless would hold up under actual gameplay, I used the 1,500-yen arcade stick from Kurume to perform durability testing by adding extra buttons (expanding to 11 buttons and adding a thumb Drive Impact button).<\/li>\n\n\n<li><strong>[First Reveal]<a href=\"https:\/\/175.41.248.22\/games\/post-200-5850\/\" target=\"_blank\" rel=\"noreferrer noopener\">Full Validation of an SOCD Cleaner Using <\/a>\"74HC132\" Logic ICs!<\/strong><br>At the climax of this series, I will take the custom SOCD cleaner circuit\u2014<strong>which utilizes two standard 74HC132 logic ICs and was previously detailed in a theoretical blog post\u2014<\/strong>and actually install it into this controller.

But the moment I found an acrylic panel of perfect dimensions at Seria (a 100-yen shop), the design process kicked off with the decision to use it as the top plate. After upcycling a broken controller and obsessing over layout aesthetics, here is the final list of parts gathered through trial and error.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Main Parts List for the DIY Leverless Controller<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Except for the key switches and button caps, the entire housing, top plate, wiring, and circuits were crafted and cut out

These feature a \"pig nose\" stem shape and seem designed for arcade buttons, with a unique pin layout. Thus, they aren't compatible with standard switches. V2 uses standard cross-shaped stems and common pin layouts, giving more freedom in choosing caps. The photo above shows test holes drilled into MDF for pins and alignment posts to check the process.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Millimeter-Precision Struggles and Priorities in Material Selection<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The list looks simple, but once I started gathering materials to build, plenty of real-world DIY solutions and traps were waiting for me.<\/p>\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Riding the Bargain Wave at Kaho Parts and Cosmic Noise<\/strong><br>For the key switches\u2014the heart of any leverless\u2014I grabbed \"Kailh Low Profile V1 Pink\" switches, which were surprisingly cheap at Kaho Parts Center. For button caps, I scored fifteen 20.8mm clear caps on sale at Cosmic Noise. This allowed me to acquire the core components on an insanely low budget.<\/li>\n\n\n<li><strong>Selecting MDF for the Internal Plate and Bottom Base<\/strong><br>For the internal mounting board, a 3mm MDF clipboard from Seria was a massive success, offering great strength and workability. However, when I picked a commercial MDF board labeled \"6mm thick\" for the bottom plate, measuring it with calipers revealed it was actually only 5mm thick (lol)! I was shocked by that 1mm discrepancy.<\/li>\n\n\n<li><strong>Creating Enclosure Walls with Tamiya Plastic Beams<\/strong><br>To create the perimeter walls for internal clearance (depth), I stacked Tamiya 3mm hollow square plastic beams in two layers. For the plunger mechanism of the four sub-buttons (tactile switches for menus), I cut and fitted pieces of Tamiya 5mm solid square plastic beams.<\/li>\n\n\n<li><strong>The 1mm Screw Battle<\/strong><br>I originally planned to use 15mm truss screws to secure the enclosure, but during assembly, I discovered they were 1mm short! I hastily switched to M3 16mm low-profile screws. However, options for low-profile screws at that awkward 16mm length were limited, making them a bit pricier than expected... By combining these with M3 nuts and repurposing 16 existing M4 nuts as spacers, I finally achieved the perfect clearance.<\/li>\n\n<\/ul>\n\n\n<p class=\"wp-block-paragraph\">All the pieces are in place. In the next post, I'll share actual work photos showing how I designed the button layout on Seria's acrylic panel and processed the prone-to-cracking acrylic material in <strong>\"Part 2: Design, Acrylic &amp; Case Fabrication\"<\/strong>\u2014stay tuned!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hello!
