I remembered whhen I first got my GHz Pandora a 13 months ago, I thought to myself there is no way Pandora could emulate PSP. So yeah, PPSSPP has come a long way.
Yeah, even I was very skeptical at the time, especially following the first PPSSPP builds where nothing was running well. Now... all I can say is "WOW"
Of course, there are still many games that don't run well or crash, but still... the amount of playable ones is quite large already.
