Timing begins on "Game start" and ends on final hit on last boss.
As of June 1, 2018, Softresetting the game (A+B+Start+Select at once) to skip the first cutscene, before beginning timing, is allowed.
Times on the Super Game Boy are automatically converted to compare with other times on the list.
Visualboy Advance/Visual Boy Advance-M (VBA/VBA-M) in any variation IS BANNED for future submissions since it emulates GB games inaccurately. It is recommended to use Gambatte or BizHawk: https://www.youtube.com/watch?v=doNLo-mn8Pw
