Sony set up an online forum where users could share their homemade games, swap programming tips, and ask questions of Sony technical support staff. Many games made by hobbyists on the Net Yaroze were released on various demo discs that came along with the "Official UK PlayStation Magazine" (as well as other official PlayStation magazines in PAL regions) from 1997 to 2004. The last "Official UK PlayStation Magazine" issue, number 108, featured a compilation with many Net Yaroze games. A promotional disc, limited to a thousand copies and featuring a number of user-developed games, was produced by SCEE and sent to PAL-zone Yaroze owners. This disc can only be played on a Net Yaroze since it requires the access card included with the system to work.
