Notes about the GSV file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The GSV file type is primarily associated with 'GameShark SP' by Mad Catz, Inc.. This file is created by the GameShark SP PC software and is transfered to a Gameboy Advance or Gameboy Advance SP using the game cheat device GameShark SP. Everything needed to transfer the game is included with the GameShark SP.
