I want to buy a PSP or Dingoo and i wanted to ask your opinion of which you think is better. Here is my criteria of what i am looking for. I like old school games, preferrably games for NES, SNES or SEGA Genesis. I own a GBA SP and Nintendo DS Lite. I tried to play Sega Genesis (JenesisDS) on my DS Lite and i didn't think the quality was great, there was a lot of choppy images and it wasn't worth playing. My favorite games on JenesisDS were emulated horribly. With NES games, i used NESDS emulator on the nintendo ds and i thought it was ok on some games, but i like Pocketnes emulator much better, but the games that i really wanted to play, were a little choppy. For NES, Mike Tyson punchout, tecmo bowl 1 and StarTropics were some of my favorite games of all time and i could find a handheld device that plays those games perfectly, i would be very happy. For Sega Genesis, RBI Baseball 1 and Tecmo Bowl 1 are my favorite all time games, and i would be happy to know which handheld system plays these games perfectly. thanks for your input.
