At 14 years old, I spent my night fixing the Hollow Knight v1.5.12620 modding crash and successfully converted DebugMod into a Standalone BepInEx 5 plugin! (No Modding API/Lumafly required)
Hi everyone,
Like many of you, I was super frustrated when the latest official Steam update (v1.5.12620) completely broke the modding ecosystem, Lumafly, and the classic DebugMod due to the new native Unity engine and D3D12 updates. The old BepInEx setups kept throwing MissingMethodException crashes in the Preloader logs because of outdated 2022 MonoMod dependencies.
So, last night, I decided to take matters into my own hands. I stayed up until 1 AM reverse-engineering, decompiling, and syncing the core dependencies to completely rewrite and convert DebugMod into a 100% Standalone BepInEx 5 plugin!
🚀 Key Features:
* No Modding API Required: Bypasses Lumafly entirely. Less bloat, zero version-mismatch crashes.
* Native v1.5.12620 Support: Fully patched to work flawlessly on the latest official Steam build.
* Clean & Independent: Just drag, drop, and play.
⚠️ Current Project Status (Beta Build):
This is currently a 99% complete Beta build.
* The default hotkey to toggle the menu is F1.
* Note: A few minor KeyCodes are currently mismatched due to the new Unity Input System updates. Everything else is working perfectly! I am actively working on re-mapping the remaining keybindings for the final release next week.
🛠️ How to Install:
Make sure you have a clean, updated version of BepInEx 5 installed in your game directory (if you get preloader crashes, completely wipe your old BepInEx/core folder and replace it with the latest 2026 build).
Download the DebugMod.dll from my GitHub release below.
Drop it into: Hollow Knight/BepInEx/plugins/
Launch the game and press F1!

As a 14-year-old solo dev, this is a massive milestone for me. Please test it out, give it a star on GitHub if it helps you, and let me know if you run into any bugs outside of the ongoing KeyCode fixes!
