I just tryed what some people from other web have been traying out. It is monkey island in a PSP now, the game dosent play, but it shows how close we are of getting a NES emulator or other games on PSP.Sponsored Links
if you want to try it out do this:
download monkey island file below
then put it on G:\PSP\GAME\TEST(make folder)
then try it.
(I don not take any credit for any of this)
