View source for Ledge Clip Jump

Ledge-Clip Ghetto Jumps (LCG) are commonly used in TAS runs. They are a notoriously precise exploit. LCGs are possible to perform non-TAS, but not consistently. If you break down the components of an LCG, as the name implies, it consists of a Ledge-Clip, followed by a Ghetto Jump. A Ledge-Clip occurs when Samus jumps up towards a ledge, and lands on the ledge while still ascending. You can think of it like her feet clipping the ledge on the way up. Precise micro-positioning is required to achieve a Ledge-Clip in most circumstances, although some Collision Geometry is more lenient than others. Definitively speaking, a Ledge-Clip entails landing with upward momentum, and when this is done, there is a single frame where Samus will enter a grounded state before losing her upward momentum. If a jump is imitated on this frame, Samus will carry over the vertical speed she landed with into the new jump. This is where the Ghetto effect comes in, as it produces results identical to what Ghetto Jumping on a slope does: it gives your jump a higher initial starting speed. Instead of a vertical speed of 0, jump can be initiated with a max speed of 11.667 or 14 vertical speed (depending on whether or not Space Jump is in your inventory).
