Hello, In my free time I made an Auto Splitter for the Wonder Boy III: Monster Lair SEGA Mega Drive/Genesis version.

It works with the following emulators:

• Kega Fusion v3.64
• SEGA Mega Drive/Genesis Classics
• SEGA Game Room

You can find it here: https://github.com/Devilquest/LiveSplit-AutoSplitters/tree/main/Wonder%20Boy%20III%20-%20Monster%20Lair

If you find some bugs or any issue please tell me, I’ll do my best to fix it.

Hope you find it useful.
