This repo contains a Livesplit USB2SNES Auto Splitter config file and a Livesplit split definition for room by room splits for ALTTP NMG Any%.

Download and setup Livesplit, QUsb2Snes, and the USB2SNES Auto Splitter according to the instructions on each of their pages (see links at bottom).

In Livesplit, right click, go to Open Splits > From File... and open alttp-splits.lss from this repo. Now add the USB2SNES Auto Splitter component to your layout (see Troubleshooting section below), and edit its settings. For the config file, open alttp-room-autosplit-config.json from this repo. Make sure the component is connected to QUsb2Snes by clicking Autodetect and the name of your device should appear in the textbox next to the button.

You'll also want to make sure your layout is using the Subsplits component instead of the Splits component so that the subsplits display properly.

Note that the autosplitter component should add a red/yellow/green line showing the status of its connection to QUsb2Snes.

Everything should be good to go at this point! Start a new save in game and the splits should start automatically as soon as you select the save.

• The Auto Splitter component spams modal dialogs as soon as I add it, saying that an empty config file name is not allowed.

  • You'll have to fight the Auto Splitter component to get the config file specified. Keep spamming the actions you need to do, hitting OK to dismiss the dialog every time it appears. Holding down Enter briefly may also help.

These splits watch the values of a few different memory addresses:

• 0xA0 - current underworld room
• 0xA9 and 0xAA - current quadrant of underworld room (needed for multi-room supertiles)
• 0x0100 - Link's current sprite (useful for post-boss cutscenes)
• 0x040A - current overworld area
• 0x0AA4 - sprite graphics index (used to detect overworld vs. underworld)
