Case doesn't correspond! It's a japanese Super Famicom 1CHIP board into the case of another Super Famicom. The board has been recapped BEFORE old capacitors started to leak. New capacitors are Through-hole Rubycon bought from Mouser. This sale includes: Recapped 1CHIP board inside of a Super...

Shipping to EU only This is useful to pump the volume of the standard MiSTer build so you don't have to turn the TV volume too high getting a background noise. Not really needed if you use a decent external DAC, but useful anyway to get a more granular control of the volume with one knob...

Shipping to EU only. For sale these PSU cables for Minigun Supergun and early Pacogun prototypes. Since I now use a 2x4 connector I won't need these anymore, they are brand new without any use. Gold plated crimp tins for lower voltage drop and better wear resistance Raychem 16AWG tinned copper...

Shipping to EU via Mondial Relay or courier. Price: 20€ + shipping. Sold locally. The joystick is the Universal model if I recall correctly but I'm not sure. Both the joystick and the buttons are made by Industrias Lorenzo (IL) and were purchased from Arcadexpress. I stopped this build...

Shipping to EU only. For sale this Sega Saturn HST-3200 in working condition. The mainboard has been recapped using good quality THT capacitors since original ones that came with the console are problematic. Remember you need a step down converter since this console is japanese, so it will...

Hi! I'm using a MiniFit-Jr connector in my Supergun and after much use I'm experiencing some voltage variation when I touch the connector, up to 0.2 Volts with hungry boards. I'm not sure if this is expectable, maybe due to normal wear in the connector or because I'm currently using a somewhat...

I propose to share Arcade related Kicad footprints with the idea of making easier to design new devices and promote rookies to start learning how to design PCBs with this free software. These are mines, shared as Public Domain. They're uploaded as .zip since the forum doesn't allow .kicad_mod...

This is a video buffer to connect arcade boards to CRT tv sets. It's based on a THS7374 with DC coupled output for RGB, color calibration and a 74HC14 sync buffer outputting 75Ω ~400mV for SCART or TTL CSYNC. It's based on THS7374 documentation, RGB's sync message, viletim's sync message...

Hi! this is the upgrade from a Shadow Warriors to latest Ninja Ryukenden. This is the version with two PCBs; I've seen another board with a 3rd EPROM board and a 74LS138 that has JP6 bridged. The only changed eproms are the labeled ones. I can confirm that this board works fine as seen in the...

Hi, I came across a Double Dragon 2 copy. It works fine but the music sounds heavily distorted, specially in some tunes, and there is an annoying background buzzing noise. Maybe the YM3012? the opamp? bad caps? https://vocaroo.com/buAtVK1qOIZ https://vocaroo.com/hJsa5aomlfl

Hi! I've found this article and I'm a bit confused about what's the best option: To AC couple or not to AC couple? That's the question! I'm doing some tests with different TV sets and games and it works with both AC coupled and DC coupled outputs. Is it really convenient or adequate to AC...

I'm looking to buffer CSYNC coming from arcade boards with a Schmitt trigger. I'm doing some experiments with a 74AHCT1G17 (single Schmitt trigger buffer) followed by a voltage divider. I've tried different boards and I get a stable ~350mV output. They work perfectly, that's very nice... but...

Hi! I'm selling adapters like this one to burn 27C301 as AM27C010 without bending pins. It just swaps pins 2 and 24, and also features a footprint for a ceramic decoupling cap. They are ready to use, no soldering needed. Just select 27C010 profile to read or write NON-JEDEC 27C301 EPROMs. You...

I'm using LW-S28A2G from Taiwan. They have some gold plating and a perfect grip, and they have a good price. Looking for an improvement I've ordered a pair of Sullins connectors, the EBM28DRXH and EBM28DREH. EBM28DRXH is cheaper than EBM28DREH and I think the pins can be succesfully soldered to...

Initially when I made this post it was called Machinegun Supergun and the design was simpler, but it has evolved into Pacogun. It pretends to be a simple, safe and cost-effective way to connect JAMMA boards to SCART TVs and audio amplifiers or speakers, with a focus on audio and video quality...

Hello, I'm working on a new setup and I'd like to know if someone can recommend me a reliable and accurate three gang pot for the R,G,B video signals. I've found P083N-071S1CBR1K at Mouser, with a Gang Error of maximum +/-3 dB (-40dB to 0dB). I'm not sure if this is good enough to get accurate...

Hi, looking for a ER5911 alternative I found this thread at arcade-museum where Riptor shows the 93C46 as an alternative. I've found there are 93C46A (128x8) and 93C46B (64x16). In the MAME driver it seems that ER5911 in Sunset Riders uses 8 bit configuration; in other place I found there are...
