Instructions
Create an online portfolio of your game development projects and accomplishments. You will not be able to obtain an official Sony developer's license if you do not have any game development experience.
Contact Sony directly and express your interest in developing for the PlayStation Network. Provide them with information regarding your online portfolio. Wait until you're granted an official Sony developer's license.
Purchase a PS3 or PSP development or debug kit directly from Sony. The cost of a kit can be as much as ten thousand dollars depending on the size of your development team. Access the SCE DevNet for more information once you have been provided with login credentials.
Read the PhyreEngine documentation to learn how PlayStation development works. Each development kit comes with a free PhyreEngine license.
Develop your game using PhyreEngine and the official development kit. Contact Sony through the SCE DevNet to submit the game for approval when the game is complete.
