Since firmware update 2.70, Adobe Flash content has been viewable on Sony's Playstation Portable (PSP) game console via the internet browser. The popularity of portable gaming is continuing its impressive growth among an increasingly diverse player base, so the ability to create games and other types of interactive experiences for the PSP is an exciting opportunity for Flash developers who wish to reach this growing pool of players and explore new types of game play.
Like any device, the PSP has strengths, limitations, and unique quirks that game designers and developers need to understand before creating content for it. This article is targeted at Flash developers who have built games for desktop computers or mobile devices, and are interested in developing for the PSP.
