The PAL versions of all 3D Classics games on the Nintendo 3DS except "Xevious" and "TwinBee" run much smoother at 60 Hz unlike the Wii's Virtual Console versions which only run at 50 Hz, mainly due to the fact the 3DS versions are semi-modified ports of their original NES and arcade versions. The Ambassador and full release versions of the NES games on the 3DS also run at 60 Hz, but NES games on the Wii U eShop are again running the PAL 50 Hz version.
