About

PSIO began as a concept in August 2010. During that time, research and development was carried out and after deciding whether or not it was feasible to continue with the project, work commenced in late 2012 where we had managed to then make the first prototype. It took many revisions until the end product was developed and was finally shipped to users in 2015.

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 own private funds and also from our generous supporters.

The Menu System did not start development until 2013, but it too went through many revisions. The end result was a Menu System that has high functionality whilst still containing an early nineties embellishment that ties in well with the PlayStation aesthetics.

The Menu System was programmed from scratch in the C programming language (with some specialised routines written in MIPS assembler for speed and size efficiency) and it consists of over 60,000 lines of code.

The idea behind PSIO is simple. It’s a flash cartridge that offers high-speed software booting capabilities over the old and generic CD-ROM assembly. This means that software may be loaded via an SD Card, or by the built in USB port on PSIO directly.

The final outcome from thousands of hours of work resulted in avoiding issues such as skipping and or freezing of software on the console itself due to old failing disc drives.
