Install OG Sound Remaster

136 megabytes and one rule: the OGSound folder has to sit beside the DLL. Get that right and there is nothing else to configure — this plugin deliberately has no settings, no interface and no config file.

OG Sound Remaster v1.0.1\ wrapper — do not copy this folder itself
- BepInEx\plugins\OGSoundRemaster\
  - OGSoundRemaster.dll 90 KB — the plugin
  - OGSound\ 136 MB — the audio bank. Must stay beside the DLL.
    - AVoice1\ Avoice2\ Avoice3\ Avoice5\ 105 files — the four American squad voice packs
    - Voice\ 30 files — German patrol lines and the dog
    - HitSounds\ 30 files — bullet impacts by surface
    - Briefing\ 30 files — all mission narration
    - Music\ 26 tracks plus the original songs.txt playlist
    - Derived\ 3 files — the only synthesised audio in the package
    - (root) 302 files — weapons, explosives, vehicles, ambience, interface
- README.md design notes and the full 1.0.1 fix write-up
- MAPPING.txt every single binding, generated from the plugin's own tables
- Source\ plugin source, the WAV/ADPCM decoder, and two verification harnesses

Copy the BepInEx folder from the archive over the BepInEx folder in your game directory and merge when prompted. Because the whole plugin lives inside a single OGSoundRemaster folder, there is nothing here that can collide with anything you already have.

The finished layout, and the only one that is correct:

Where the plugin and its bank must sit

<game folder>\
  DeadlyDozenReloaded.exe
  BepInEx\
    plugins\
      OGSoundRemaster\
        OGSoundRemaster.dll
        OGSound\            <- 526 audio files + songs.txt

02 Launch and read the report line

Start the game. On the console you are looking for the bank size, the memory budget it chose for itself, and a hook count:

The three numbers worth checking

[Info   :   BepInEx] Loading [OG Sound Remaster 1.0.1]
[Message: OGSoundRemaster] OG Sound Remaster v1.0.1 - StixsworldHD (StixsmasterHD4k)
[Info   : OGSoundRemaster] Indexed bank: 526 files
[Info   : OGSoundRemaster] Memory budget: … MB   decode threads: …
[Info   : OGSoundRemaster] Hooks installed: 33/33

Line	Expected	What a wrong value means
Indexed bank	526	Anything lower means files are missing. Anything at 0 means the `OGSound` folder was not found — check the nesting.
Memory budget	96–384 MB	Derived, not configured: 6% of system RAM, clamped to that range. Realistic steady-state footprint is around 110 MB.
Hooks installed	33 / 33	Three sit on the audio hot path (`AudioSource.Play` and both `PlayOneShot` overloads); the other 30 are one-shot bindings on the game's own `Awake` and `Start` methods.

03 Confirm it in-game

Start mission 1. Three things should be immediately, unmistakably different if the plugin is working:

The briefing narration. The 2002 voice actor, not the remake's. This is the loudest single tell and it happens before you have moved.
The mission music. Mission 1 plays sneaky02 and tension01 — read verbatim from the original game's own songs.txt, not chosen by ear.
Your squad's voices. Order any soldier to move and you get one of the four original American voice packs, cycled across your squad.

04 The report file

While the game runs, the plugin writes a diagnostic file next to itself, refreshed every 30 seconds and again on exit:

<game folder>\BepInEx\plugins\OGSoundRemaster\OGSoundRemaster.report.txt

It records, in order of usefulness:

Which hooks applied and which did not — a game patch shows up here first.
How many fields and clip sets were bound, and how many loose sound players were matched by name.
The indexed bank, resident clip count, and memory used against budget.
Every clip matched by name, with a confidence score.
Every remake sound that had no confident original counterpart and was deliberately left alone.

That last list is the one to read. If something in your game still sounds like the remake and you expected it not to, its name will be in there — and that is a far more useful thing to report than "a sound is wrong".

The file is diagnostics only. Deleting it changes nothing; it will be written again on the next launch.

05 Why there is no config file

This plugin never calls Config.Bind, so BepInEx never creates a .cfg for it. There is nothing to tune and nothing to open. If you go looking in BepInEx\config and find only BepInEx.cfg and the Ungodly GFX file — as in Plate 05 — that is correct.

Everything that would normally be a setting is derived at runtime instead:

Would-be setting	How it is decided
Memory budget	6% of system RAM, clamped to 96–384 MB
Decode threads	`min(3, CPU cores − 1)`, minimum 1
Which sounds stay resident	Anything ≤ 3.5 s is pinned; longer clips load on demand and are evicted after 25 s idle
Loop vs single-shot weapon fire	Read from `fireSound.loop` at bind time
Mission music	Taken from the original game's own `songs.txt`
Vehicle recordings	Chassis family inferred from the vehicle root object's name

Under the hoodWhy three files in Derived\ are synthesised

The 2002 original ships burst loops for the three automatics, not single shots. Reloaded triggers fireSound once per bullet, so feeding it a one-second loop would stack a dozen overlapping copies into mush.

The shot rate was measured out of each loop by transient detection and one clean shot was cut from it: MP40 at 684 RPM, Thompson at 1250 RPM, MG42 at 1148 RPM. That MG42 figure landing near the real weapon's ~1200 RPM is a good sign the detection measured what it should have.

These are the only synthesised files in the package, they live in their own folder, and the plugin only reaches for them when it sees fireSound.loop == false. If a future patch makes those sources loop, the original loop files are used instead, automatically.

Before moving on

BepInEx\plugins\OGSoundRemaster\OGSoundRemaster.dll is in place.
OGSound\ sits beside that DLL, not one level deeper.
There is no OGSoundRemaster\OGSoundRemaster\ anywhere.
The log reports an indexed bank of 526 files.
The mission 1 briefing narration is the 2002 voice.
Squad orders play the original voice packs.
