Distribute home-made games on your PSP

Despite the major firmware upgrade the PSP got last month in Japan (and iwll be getting here soon), Sony Computer Entertainment platform development chief Izumi Kawanishi is already talking about what may be possible for the Sony PSP in the future. Those Sony guys, not the type to underplay much. They are looking into adding Macromedia Flash and extended Javascript support to the PSP web browser as well as releasing some USB peripherals. What piqued my interest is the fact that Kawanishi stated that they're thinking about making games downloadable (hello PSP game piracy) and it would be interesting if users could make and distribute their own "simple" games. Hell to the yes. That would possibly boost PSPs street cred. As of now, the PSP is getting whumped by the DS. Where's the PSPs answer to Nintendogs?
