Only versions 1.0 and 1.5 firmware PSPs can run homebrew. 2.00 firmware version can run partial homebrew in userspace (most homebrew requires more than 64kb of memory).
Can I downgrade my 2.00 PSP?:
Yes. Check out http://www.pspupdates.com/ for more information. Files will not be provided here.
Can I downgrade my 1.51, 1.52, 2.01 or 2.50 PSP?:
Yes, yes and no. 1.51 and 1.52 will have to be upgraded to 2.00 then downgraded to 1.50. Version 2.01/2.50 is currently not downgradable.
