Here's the first release of this project. It has been tested and is working fine, so just enjoy!
NOTE: I recommend using 1k resistors for R1 through R10. I have checked on a real PsOne and that's the value it uses, so I guess we should do the same. This will be fixed in the next release.
Note that the released gerber files are password-protected. The original reason behind my projects was to allow anyone to make their own retrocomputing accessories cheaply. Instead of this, what I achieved was actually fuelling greedy people grabbing my work, making boards for a couple of bucks and the selling them at outrageous prices ($15 for a badly-soldered OpenC64Cart that costs $2 to make is just ridiculous).
I still believe in free software and open hardware, and that is why my projects will remain as such. I am no longer providing ready-to-use gerber files, but you can still generate them from the KiCad project or ask me for the password, if you think you don't fit the above statement.
If all you want is to get boards made, I would really appreciate if you did it as explained in the Support section in order to get them cheaply while supporting the project, i.e.: just click on this button:
Note that you are still allowed to sell these boards, I have nothing against that as long as you do so at an "ethical" price. This is why I am adding the following restriction (inspired by DiagROM): if this board is sold at more than 8€ (as of today), 25% MUST be donated to a LEGITIMATE charity of some kind. I suggest research against cancer, but feel free to choose whatever suits you best.
