building game for other platforms

[psychicgoldfish]

Hi! I couldn't find information on this anywhere. I'm a noob, so forgive me if the answers are obvious.
How do I build my game for devices such as the PSP? There is also the "Future Possible Platforms" list, if it's already possible to port to any of those then that'd be cool too.
Thanks in advance, this engine is super cool and I look forward to using it more.
