Medic File Mod Merger - Install and Combine File Mods 1.0.1

A Mod for Helldivers 2
Medic File Mod Merger - Install and Combine File Mods akl_mod_preview_image
Install and combine settings-file mods in one click. Works after the EAC update.

Since the October 20 update, gameplay mods (vaulting, water, movement, stratagems...) change the game's settings files. Each of those mods brings its own installer, and two mods that change the same file can't both be active: whichever runs last wins, or one refuses to install.

This app fixes that. It reads the mods, merges their changes into one file per game file, and writes them straight into the game. No loader, no launch-and-quit, no mod manager needed for these mods. One click undoes everything.

How to use
  1. Quit the game. Start Medic-File-Mod-Merger.exe (no install needed). It finds your game folder by itself.
  2. Drag mod zips or unzipped mod folders onto the window.
  3. Order matters: when two mods change the same value, the one higher in the list wins (^ and v buttons). Mods with options get a drop-down.
  4. Press APPLY CHANGES. Start the game. Done.
To change or remove mods: change the list, press Apply. Uninstall all puts the stock game files back.
If one of these mods is also ticked in your mod manager, untick it there and deploy - the app warns you about it.

Mods it can read
  • Mods built on the HD2 file-mod installer: Stratagem Balls Stay Put, Consistent Vaulting, Shallow Water Diving, Jump Pack Recharge, Slidedivers / HELLSLIDERS, RoComp packages...
  • Alice's Enhanced Stratagem Collection (all 15 combos, with the English names next to the Chinese ones)
  • Packs that keep several game files in one .stream with toggles (the toggles become a drop-down)
  • Mods that ship plain generated_*.dl_bin files (one variant per folder)
Not merged, by design:
  • Lua mods, models, sounds, Treasure Radar, Objective Tracker... - they don't change settings files, keep them in your mod manager. The app tells you.
  • A mod that changes a file's length (Jump Pack Recharge) can't be mixed with other mods that change the same file. It is installed as it is, and the app tells you which mod was left out.
  • Programs that edit the game files themselves, like SHODAN or the Stratagem Extra Pairs configurator. Use them after this app. To change mods here later: press Restore in that program, Apply here, then Install in that program again.

Conflicts
When two mods set the same value, the app shows a CONFLICT line and the mod higher in the list wins - you pick by changing the order. Example: Consistent Vaulting raises the slide angles (you slide less), HELLSLIDERS lowers them (you slide more). Put the one you want on top; everything else from both mods still applies.

After a game update
Updates replace the game files, so file mods stop working - nothing breaks, the game is just stock. Open the app: mods made for the old version show NEEDS NEW VERSION. Add the updated versions and press Apply.

Safety
  • Never writes over a game file it can't identify, and never puts an old stock file back over a newer one.
  • Keeps its stock backups and a log in <game folder>\MedicFileModMerger. Steam > Verify integrity of game files always gets you back to stock too.
  • Windows may say "Windows protected your PC" the first time - the exe isn't code-signed. More info > Run anyway.
  • Tested in game with mods from three different authors installed at once (Medic3038, Alice, HELLSLIDERS).

Bug reports
Please include <game folder>\MedicFileModMerger\log.txt.

Credits
  • The authors of the mods above, whose formats it reads (it doesn't include any of their files).
  • Built in Rust with egui; third-party licences are in the download.
  • Me... Duh.

So I'd like to use Vaulting, Balls stay put, and shallow water diving. I merged them into a zip to use with Arsenal. When I install it with Arsenal, it conflicts with Boot Mod Loader. Any idea how to fix it so they play nicely together?
You merge them and deploy/install them in the merger itself. You dont have to install it with arsenal.

Feel like when merging many mods with hellslider, the vaulting seem to be impossible and player slide on every single rocks. (´・ω・`)

Well regarding that, the vaulting mod rn is kinda buggy with certain terrain and might get worse with the hellslider, I'll add an update soon regarding that.

Good morning/afternoon/night, sir. May i ask, since im using a mod manager and i used the option to merge into a pack ¿Do i have to do launch the game, esc quit, then rejoin to load the mods? or is launching enough?

If you're talking about the qol file mods, you put them in the merger, install them and launch. Dont need to esc quit or rejoin. If you're using a mod manager like hd2 or arsenal and you deploy using those, you would have to do the esc quit and restart.

Is there a particular reason the functionality to merge mods with different file lengths was left out? It doesn't seem like a technical limitation but an intentional choice

Yeah that was intentional, the merger does merges by offset, different file lengths mean either data has been added or removed and merging these two based on offsets wouldnt be possible or atleast wouldnt be safe, will need to have a comparision between stock and a given mod and then note the offsets of each mod and then decide on a merge. Its like matrix addition, you cant add matrices of different dimensions, only same dimensions can be added.
