While native to Switch, emulation on Yuzu/Ryujinx matured in 2021. Autosplitters for SMO had to read emulated RAM rather than native PC memory. The GitHub repositories from this year specifically note: "Updated for Yuzu EA 1500+."
These tools are often built as scripts, a simple scripting language that allows creators to define memory addresses to watch. autosplitter+games+github+2021
: 2021 marked a transition toward using WebAssembly (WASM) for auto splitters. This allowed splitters to run in LiveSplit One (the web and cross-platform version), making them safer and more portable than traditional DLL-based splitters. While native to Switch, emulation on Yuzu/Ryujinx matured
If you are looking for a specific autosplitter from a game played in 2021, here is your treasure map: : 2021 marked a transition toward using WebAssembly
Many 2021 autosplitters are still the best available, but GitHub’s dependency changes (e.g., LiveSplit Core updates) broke some. If you’re maintaining a splitter, check if it’s from that era – it might just need a recompile.
An autosplitter is a script (usually written in ASL or C#) that hooks into a game's memory. Instead of relying on a human to press a button, the script watches for specific memory values to change—such as a loading screen starting, a boss’s health hitting zero, or a level ID changing.
In the speedrunning world, every millisecond counts. Manually hitting a timer (like LiveSplit) is prone to human error. Leo’s goal was to create a script that would: Detect the exact frame a boss died or a level loaded.
