Eucfgbin
EUCFGBIN is a binary encoding format with the following core characteristics:
A valid .eucfgbin file begins with the bytes: 45 55 43 46 47 42 49 4E (ASCII: “EUCFGBIN”).
In continuous integration, temporary binaries are often named by concatenating environment variables:
Example: eucfgbin might be generated by a Makefile rule: eucfgbin
$(EU)_$(CFG)_$(BIN): ...
(Assuming this relates to European server configs or game settings)
Post: 🇪🇺 EU Settings Update!
Just pushed the latest EU Cfg bin updates to the server. 🚀 The ping should be significantly smoother for everyone connecting from the region. EUCFGBIN is a binary encoding format with the

A minimal EUCFGBIN file containing "sensor_period_ms": 500, "region": "EU-DE" would be encoded as: A valid
| Field | Hex Dump (excerpt) | Meaning |
|---------------------|----------------------------------------|---------------------------------|
| Magic number | 45 55 43 46 47 42 49 4E | "EUCFGBIN" |
| Version | 01 00 | v1.0 |
| Payload length | 00 00 00 1A | 26 bytes |
| TLV: key "period" | 04 00 (key len=4) 70 65 72 69 6F 64| "period" |
| Type int32 | 03 | int32 tag |
| Value length | 04 | 4 bytes |
| Value | 00 00 01 F4 | 500 |
| TLV: key "region" | 06 00 72 65 67 69 6F 6E | "region" |
| Type utf8_euro | 10 | UTF-8 Euro |
| Value length | 05 | 5 bytes |
| Value | 45 55 2D 44 45 | "EU-DE" |
| Checksum (CRC-32C) | A3 B1 C2 D4 (example) | |
Total size: 8 (magic) + 2 (version) + 4 (len) + 26 (payload) + 4 (checksum) = 44 bytes.
Equivalent JSON would be ~60 bytes, but parsing EUCFGBIN is ~8× faster on ARM Cortex-M4 benchmarks.
