Speedrun timer with autosplitter for fxpak/sd2snes

About

This is a simple barebones re-imagining of LiveSplit + autosplitter for SNES (sd2snes/fxpak + qusb2snes or SNI). It's named for the phylum of segmented worms, because segments.

It currently only supports Super Metroid, but other SNES games could be easily added. The Super Metroid support is based on SuperMetroid.asl.

It's written in Rust using egui. This means it should work on Windows, macOS, and Linux. However, I've only tested it on Linux.

Dependencies

You will need qusb2snes or SNI so that the autosplitter can read the SNES memory (console or emulator). Beyond that, it should build and run on Windows, macOS, and Linux.

Getting Started

The easiest way to get Annelid is to download a release build for your OS: Releases

Once you have Annelid running, you can right-click to import a layout and splits from LiveSplit. Then use the Autosplitter editor to create an autosplitter logic that matches your splits.

Linux

Your user account will need to be in the input group. This is so we can support global hotkeys. You can check if your account is already in the input group by typing:

id <your username>

For example, my username is dagit:

$ id dagit
uid=1000(dagit) gid=1000(dagit) groups=1000(dagit),4(wheel),8(floppy),10(lp),11(dialout),12(audio),13(video),16(cdrom),17(optical),24(kvm),25(input),101(xbuilder),984(vboxusers)

Notice 25(input), that means my account is part of the input group. To add your user to the group if it's not already there, use this command:

sudo usermod -a -G input <your username>

Once you've added your user account to the input group you may need to reboot or log out of your graphical session.

Building

You'll need to install Rust. I recommend using rustup. Once you have the rust toolchain installed, clone this repository, and then type:

cargo build --release

If the build is successful, you can run it with:

cargo run --release

If you see the message:

Error: "No devices present"

That means you need to turn on your SNES and make sure that qusb2snes is connected to it.

TODO

• Settings editor. A tree view with checkboxes should work pretty well for configuring autosplit behavior.
• Named settings that can be saved/loaded
• Right-click menu for:
  • Settings editor
  • Save/Load splits and settings
  • Way to select your usb2snes server
  • Toggle for latency display
• Keybindings for skipping a split, undo, pausing, and stopping. Whatever livesplit supports.
• Make sure the logic for starting a new run starts from a fresh snes state
• Implement comparisons
• Fix the horizontal sizing, currently hard coded
• Allow it to start up without a connection and stay running when the connection dies
• Do something to avoid refiring splits in the case of reset or death mid run.

Cross compiling

For Windows

sudo xbps-install -Su cross-x86_64-w64-mingw32
rustup target add x86_64-pc-windows-gnu
cargo build --target x86_64-pc-windows-gnu
wine ./target/x86_64-pc-windows-gnu/debug/annelid.exe

For macOS

This fails because it needs all the Apple frameworks and there is currently no way to test it from linux. So cross compiling to macOS effectively doesn't work yet.

However, it may still be useful to list the target in case those things change.

rustup target add x86_64-apple-darwin
cargo build --target x86_64-apple-darwin
