I've been working on making a universal storage system for all my arcade PCBs to minimize the handling needed. Basically they are just a 3d printed boxes I resize and the I drill small holes in the base where I want things to line up. I use M3 heat inserts and thumb screws for the HAS V5...

I need some help getting this board going again. I messed up one of the EPROMs and need to reprogramed it however it seems to be running a non standard rom set. I thought it would be as simple as dumping the roms and figuring out what rom set it has and reprograming the missing rom. My rom...

This board wasn't booting but I was able to resolve that issue. I thought it would be as simple as replacing the encrypted chip with a z80b and replacing the A7 eprom but no dice. I do ear a small hum that gets louder or quieter if I turn the volume pot. Z80b 6 clock = pulsing 16 INT = L 17...

I'm finding mixed info about shinobi and the encrypted chips. Some of the info I am finding is that Shinobi will just lose sound if the battery fails. I am capable or replacing the CPU and reflashing the eproms without an issue. I was just wondering if Shinobi with no picture can be related...

I decided to start a project to make it easier to store and play my recently collected arcade boards along with take up less space. In cringe every time I remove the bubble wrap from them. Obviously I am designing it to play with the top off which makes sense for cooling anyway. The HAS...

Made this because this game needs a dedicated joystick. Print the custom graphic borderless on 8x11 photo paper. I included a template for drilling the holes printed on 8.5x11 paper. I'd upload the fusion file for the base but it is too large. 8.5x11 1/8" 3mm acrylic sheet - No need to cut...

I included a screenshot of the map it is happening on. On occasion I see patches of small white dots like static. I have seen this happen before with other games when an EPROM is failing. Any idea what eprom it could be or any other ideas as to the cause. Trying to avoid pulling them all and...

I'm looking to make a Karate Champ arcade stick for my HAS. Bolt patterns and such don't matter as I will 3d print a case for whatever I use. I'm looking for something aftermarket that would have the closest feel to the original that is readily available. No need to use original Data East...

I just designed this model that incorporates 1/8" 8.5x11 Plexiglas over a borderless printed 8.5x11 photo any inkjet can print. Amazon sells the plexiglass in that dimension already so you just need to drill the holes and buttons. I'll share the files and build list soon after I print another...

I figured I would put this out there because I didn't see anything like it on the usual 3d printing sites. First 3d model I ever made so sorry if it's rough. I included an STL without the HAS support. I traced around the solder point's so it shouldn't put pressure anywhere you wouldn't want...

I purchased a few boards so I can practice learning how to troubleshoot arcade games. This one is a Wrestlefest that was "untested" from eBay. When I plug it the supergun I can see the screen pop like it registered power was plugged in and nothing else happens. I dumped all ROMs except IC 0...

Solved - To anybody that may ever see this thread. The primary issue was caused by cold solder joints at IC36 SN74LS25N logic chip. I also had bad PCM sound chip M5205 which causes popping on some sounds. There is good information below on the troubleshooting involved in fixing it. I just...
