PSIO began as a concept in August 2010, and development did not start until late 2012 where the first prototype was designed from scratch. It took many revisions and prototypes until the end product was developed. Here are just a few of the several revisions we went through. Everything was hand soldered from scratch with component and equipment funding coming from our generous supporters.


It appears that some games will require patching before working with the PSIO.  While it’s understandable that some games might require special treatment, it seems quite a large portion of the console’s library will require specific patching for this device.  

CybDyn claims 99% Compatibility across the PlayStation Library.
