Importing a .rec file

package main

import (
	"log"
	"os"

	"github.com/redraskal/r6-dissect/dissect"
)

func main() {
	f, err := os.Open("Match-2026-03-26_21-19-17-21932-R01.rec")
	if err != nil {
		log.Fatal(err)
	}
	defer f.Close()
	r, err := dissect.NewReader(f)
	if err != nil {
		log.Fatal(err)
	}
	// Use r.ReadPartial() for faster reads with less data
	// dissect.Ok(err) returns true if the error only pertains to EOF (read was successful)
	if err := r.Read(); !dissect.Ok(err) {
		log.Fatal(err)
	}
	print(r.Header.GameVersion) // Y11S1_Alpha03
}

Updating Operator Data

When new operators are added to the game, regenerate the operator roles mapping:

go generate ./dissect/...

This scrapes the current operator list from Ubisoft's website and updates dissect/operator_roles.go.

I would like to thank stnokott for their work on r6-dissect, along with draguve & other contributors at draguve/R6-Replays for their additional reverse engineering work.
