.SLP File Extension

SLP files save references to the source media files, layers, edits, and applied filters. SpectraLayers Pro was developed by Sony until it was sold to MAGIX in 2016, and then was acquired by Steinberg in 2019.

Project Slippi is a fan-made extension to Super Smash Bros. Melee that adds several features. One of the features Project Slippi adds is the ability to automatically save match replays as SLP files.

With this feature enabled, after a match played using Project Slippi concludes, the program automatically saves a replay of that match and the match's statistics in an SLP file. Players can watch the replay by transferring it to their PC and opening it in Slippi Launcher, which is available for Windows, macOS, and Linux.

You can open an SLP file in Slippi Launcher (multiplatform) to play the replay it contains. The easiest way to open an SLP file is to place it in the ~/​Users/​YourUserName/​Slippi directory, select Slippi Launcher's Replays tab, and then open your SLP file.

To import an SLP file into StormLoader, select the Add button located in the program's upper left-hand corner. You can import any number of SLP files before launching a modded game of Stormworks (by selecting StormLoader's Launch button).
