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.
The Menu System did not start development until 2013, but it too went through many designs. 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 system. It was programmed in the C programming language (with some specialised routines written in MIPS assembler for speed and size efficiency), and it consists of over 50,000 lines of code which were written from scratch.
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.
