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.
