Quick Answer
Install Maskoliver's original UsefullInfoUI package from Thunderstore through a separate r2modman profile. Launch the modded profile and press F1 to switch between Default, Detailed and Hidden views. Do not install MelonLoader and BepInEx together in the same game folder.
Current Version and Compatibility
Trusted Download Source
Use the original Maskoliver UsefullInfoUI page on Thunderstore. Confirm the author, package name and dependency string before installing.
- Prefer the package page's manager install button over a third-party mirror.
- Review the package's Versions, Changelog and Analysis tabs before an update.
- Do not run a separate installer claiming to be required by this small DLL mod.
- Back up your save and keep leaderboard attempts on a clean vanilla profile.
Recommended Install: r2modman + BepInEx
- Create a separate Megabonk profile. In r2modman, make a test profile named with the current game version. Keep your clean profile unchanged.
- Install the original package. Open UsefullInfoUI from the Megabonk Thunderstore catalog and choose the manager install option.
- Confirm the loader dependency. The profile should use BepInEx 6 for IL2CPP. Let the manager install declared dependencies instead of adding a random loader build manually.
- Launch modded. Start Megabonk from r2modman's modded launch button, enter a low-stakes run and press
F1. - Verify before adding other mods. If the overlay works alone, add other packages one at a time so a conflict remains identifiable.
Manual BepInEx path
If you deliberately install the DLL manually inside a manager profile, the package readme specifies:
<profile>\BepInEx\plugins\UsefullInfoUI\UsefullInfoUI.dll
Alternative: MelonLoader Install
The package also lists MelonLoader v0.7.1 support. Install that loader into the game directory, then place the DLL at:
<game>\Mods\UsefullInfoUI\UsefullInfoUI.dll
How to Use the Overlay
Default → Detailed → Hidden.
Applies config changes without a restart.
Enlarges both overlay panels.
Shrinks both overlay panels.
The left panel can show run counts such as Shrines, Chests, Vendors, Microwaves and Moai. The right panel can show Damage, Crit, Attack Speed, Luck, Difficulty, XP/Gold Gain and other player stats.

| Symptom | Likely cause | What to do |
|---|---|---|
| No overlay after F1 | Vanilla launch, missing loader or wrong folder | Launch modded from the correct profile and confirm the DLL exists in that profile. |
| Game crashes on launch | Loader conflict, stale dependency or new game patch | Remove one loader, disable other mods and retest UsefullInfoUI alone in a fresh profile. |
| Config file missing | The mod has not loaded successfully yet | Fix the loader/package first; the config is written on the first successful run. |
| Config changes do nothing | Wrong profile, unsaved file or invalid key | Edit the active profile's file, save it and press Ctrl+R. Copy names from its comments. |
| Overlay is too large | Scale value or UI scaling | Press Ctrl+Down or lower both scale values in the config. |
| Worked before an update | Game/API compatibility changed | Disable the mod, confirm vanilla works, then check the original package for a newer version. |
Clean Uninstall
- Close Megabonk completely.
- In r2modman, disable or uninstall UsefullInfoUI from the affected profile.
- For a manual install, remove
UsefullInfoUI.dllfrom the relevant BepInEx or MelonLoader folder. - Optionally delete
UsefulInfoUI.cfgif you do not want to preserve your layout. - Launch the clean profile and verify the game before removing the loader itself.
Removing this display mod should not require downloading a replacement save. Keep the backup until the clean game has launched and loaded normally.
Safety and Leaderboard Boundaries
- Use only the original author package and a known mod manager.
- Scan manual downloads and reject unrelated executables or password prompts.
- Keep a vanilla profile for clean saves and leaderboard attempts.
- After any Megabonk update, launch vanilla first and re-enable mods individually.
- Never publish support logs without checking them for usernames, local paths or private data.
UsefullInfoUI FAQ
How do I mod UsefullInfoUI into Megabonk?
Create a separate r2modman profile, install Maskoliver's UsefullInfoUI package from Thunderstore, let the manager include BepInEx 6 IL2CPP, then launch modded and press F1.
Is it UsefulInfoUI or UsefullInfoUI?
The official package name and DLL use UsefullInfoUI with two l's. Its generated config is named UsefulInfoUI.cfg with the conventional single-l spelling.
Does it support BepInEx and MelonLoader?
Version 1.2.0 lists BepInEx 6 IL2CPP and MelonLoader 0.7.1 support. Choose one loader only; do not combine both in one game folder.
Does it work on the latest Megabonk patch?
The package author only states testing on Megabonk v1.0.19. Treat later versions as unverified until tested in a separate profile or confirmed on the original package page.
Can I hide the overlay without uninstalling?
Yes. Press F1 until the state cycles to Hidden. You can press F1 again later to restore Default view.
