Further to Sony's announcement of its Minis program of small downloadable games on PSP, a two-page PDF marked Level 2 Confidential, and detailing the basic technical requirements and approval process for the service, has leaked onto the internet.
In this, Minis are described as being "fun, affordable, creative, easy to play, and different".
Interestingly, Sony details the process by which Minis are submitted and approved. There is "no requirement for content approval," apparently.
Games will, however, go through a shortened quality assurance process to make sure they work properly on the various PSP hardware.
Significantly, this process is labelled as being "transparent, trackable and predictible", with developers setting their own release dates.
This suggests Sony has learnt from Apple's approval process for the App Store, which is regarded as being neither transparent, trackable nor predictible.
When it comes to the business model, Sony says developers will be paid on a monthly basis, and there's no penalty for minimum sales or bandwidth charges
However, they will have to pay €1200 for a PSP development tool.
