This isnt PSP news but being as the Dreamcast Scene and more importantly the DCEmu network was founded by the Dreamcast site its worth a plug.
Today saw the relaunch of a site that is 360 pages in size featuring every emulator and all the Homebrew for the last 2 years.
Heres a screenshot:
If you thought the PSP was great for easy to use Homebrew and Emulation then the Dreamcast is the perfect console to carry that dream along. the scene still trives even after all these years since Sega ditched the console.
Most Dreamcasts can be picked up for $40 or less and then you enter a world of free software like no other. Check out the worlds premier Dreamcast Site at http://www.dcemu.co.uk
