a "Hello, World!" message. For us, that metric is determined by how long it takes to get a Sega CD emulator running on the system. For the PSP Go, that period of time has been finalized: 43 long, lonely, Night Trap-less days.
A YouTube video by "Neon" from "Team Typhoon" (is that some sort of gang?) appears to prove that on some PSP Go, somewhere in the world, one can play Sonic CD. Don't get your hopes up -- the video's annotations repeatedly promise that the hack will not be released to the general public, so for the time being, you're going to have to keep playing that old copy of Wirehead on your clunky, Voltron-esque home console. Still, our heart swells knowing that our wildest dreams are possible -- if not slightly out of reach.
