The Net Yaroze project started in March 1997 and was Sony’s attempt to allow bedroom coding for the PS1, making it something of a predecessor to Microsoft’s Xbox Live Indie Games. Basically, a dev kit, the $750 USD package contained a special black-colored debugging PlayStation unit with documentation, software, and no regional lockout. A computer was still used however to write the code, compile it, and send the program to the PlayStation.
