eeu.ctr — Country Table
Status: ✅ Cracked · 1.6 KB · NOT_COMPRESSED · 35 records
The closed list of countries this disc's "EEU" (East Europe) dataset covers.
Layout
- Same 94-byte header.
- Fixed 43-byte records, 35 on the reference disc:
| Bytes | Field |
|---|---|
[0] |
Sequential index (0–34) |
[1:36] |
Name, UTF-8, NUL-padded |
[36:39] |
ISO 3166-1 alpha-3 code |
[39:41] |
ISO 3166-1 alpha-2 code |
[41:43] |
2 trailing zero bytes |
Validation
Record 19 is "BALGARIA", codes BGR/BG — an exact match against a
reference photo of the real unit's own Address Entry Country screen. The
full 35-country list decodes cleanly, including one country listed
twice: Russia, once transliterated "ROSSIYA" and once in Cyrillic
"РОССИЯ", both correctly RUS/RU.
Practical relevance
eeu.cty's own per-record "country tag" field (bytes [57:59], see
eeu.cty) partitions all 939,351 city records
into exactly 35 groups matching this table — used by the map viewer's
Country → City → Street address-entry scoping.
