Golden Yoshi's Island is a ROM Hack of Yoshi's Island built to be played for live audiences in a speedrunning setting. It's a modified version of SMW2+2 by Golden Yoshi (with his full consent).
This hack features several optimizations to make it a faster run than its source material, based on feedback from the Yoshi speedrunning community:
-36 levels hand-picked from the original ROM Hack's 50 and rearranged into 4 worlds.
-Default egg aim setting is now Hasty
-Transformation sequence has been sped up
-World-clear cutscene has been removed
-Message box upon collecting first flower has been removed
-Autoscrolling sections removed
-New tech to skip vehicle sections
-Various other sections of levels have been modified for brevity and consistency
-Entering the top secret code now triggers the credits sequence
-Brand new title screen and credits sequence, courtesy of Mattrizzle
