Small tool to extract audio from CV1000 games to .wav files. https://github.com/alamone/cv1000-to-wav/ CV1000 audio uses AMM ("AMusement Music compression"), looks to be a Yamaha proprietary format based on MPEG Layer 2.5, which supports 16000Hz (used by CV1000) and 32000Hz encoding. This is...

Hi everyone, temporarily back from the dead. I've developed a mod for Gradius III (JP) that provides the following: - A numeric lives counter, so you actually know how many lives you have (normally, the game just shows a modulo of your lives to fit on limited screen space) - Display current...

Purchased a PCB from me, payment sent quickly and smooth transaction. Thanks!

Fully working. Asking $750 shipped to US, + shipping cost outside of US. Paypal F/F (or +fees) or Zelle. Currently setup as Truxton II, but can convert it to Tatsujin-Oh if you want. Thanks for looking.

So, anything like this out there? What I'm hoping for is something like camelcamelcamel, but tailored towards arcade PCBs - would show historical sold prices on ebay, YAJ, surugaya, mercari, forums, etc. Might be hard to automate for forums, but ebay and YAJ you could probably use their API or...

My Namco System 1 has died (garbled video, probably CUS123 is dead), looking for a replacement board, let me know if you have anything for sale, thanks.

For sale is a dead Seibu SPI board, no video output when turned on, it used to have a Viper Phase 1 USA cart installed. For parts or repair. Asking $40 + shipping to your location. Thanks.

This is an idea that I was thinking about, using something like LTC6904, which is an adjustable oscillator programmable from 1kHz to 68MHz. The idea is to hook this up to a microcontroller and then replace the existing crystal oscillator that is used to clock the main CPU on an arcade PCB, e.g...

Wondering if there's something out there. A lot of times I'm looking for high quality pictures of PCBs but I have to go search google and all I find is crap low quality pics or dead auctions etc. Ideally I would like a searchable database that would show high resolution pictures of front and...

I have a lot of SPI carts but only one (working) motherboard. Looking for another one so I don't have to swap carts. Thanks.

I made a switch to select Old/New version on Viper Phase 1. Seibu1-4: 27C040 -> 27C801 Seibu5: 27C1024 -> 27C4096 (I did not have any 27C2048 handy) Seibu6: 27C512 -> 27C010 (Need to tie pins 32 and 30 for VCC) Youtube video

Inspired by the Astro City Mini V... I decided to start measuring the "native" lag of PCBs - that is, the lag from sending an input signal (measured by an inline LED) until the PCB recognizes the input. I've only tested a few PCBs so far but I will continue to test my collection. In response to...

Lurker here. I have developed mods mostly aimed at practicing shmups. The Gradius IV mod in particular has a lot of options, including stage/loop select, pause, and full power anytime (A+B+C during pause). The Dodonpachi mod fixes a lot of bugs with the original, especially with regards to 2P...

As in the title. Thanks
