This script recreates Zelda 2's Inventory Menu in Lua using Bizhawk. This is actually a zip with a ".lua" extension. Cannot normally upload zips here so added ".lua". Just rename to zip removing ".lua", then extract again.

Ganbare Goemon - Ooedo Daikaiten (Japan) double jump glitch at line 83300.bk2
This bk is originally from me just playing the game normally and encountering the glitch.
For one, I am not sure if that works outside of towns
but the idea is that you jump, attack, then you can press and hold jump. Holding jump is like jumping in a lot of games where you hold it and you jump higher.
