Well, as most will probably know: Super Mario Bros2 for nes is actually super doki doki panic (sp?) with mario sprites, and the real smb2 never left Japan. So I finally decided to give it a try. From the 6 roms mentioned in GoodNes only 2 can actually be started in the emulators, and only one is without sprite errors. So far so good, however in that sole working version, the game freezes after the 4th level Guess I could switch to Lost Levels on the SNES, but I've heard it is easier (you can load for example), so I wonder if anyone managed to play the true smb2 on a NES emu. If so what version of the rom did you use? What Emu?
