However, I need to provide some important clarification:
I understand you're looking for a of Grand Theft Auto: Vice City to download for the Nintendo 3DS .
Grand Theft Auto: Vice City was never officially released for the Nintendo 3DS by Rockstar Games. The only portable GTA games from that era were GTA: Chinatown Wars (DS/PSP) and later ports of GTA III/Vice City on mobile (iOS/Android) and PS Vita.
