User:Dinoguy1000/.YGC, .YGL, and .YGR files

.YGC, .YGL, and .YGR are file extensions used for the Tag Force games for (downloadable only?) cards, status lists, and Deck recipes, respectively. These files seem to always be named YGTF###.YG_, where ### is a three-digit number counting up from 000 and _ is one of C, L, or R as appropriate for the type of file.

.YGL

Cards seem to be sorted such that Forbidden cards are listed first, followed by Limited, and then Semi-Limited (but not always).

string(4) - header YGTF

byte(4) - unknown 1

int32(4) - Offset to card count (count_offset - this is a decimal offset, not a hexadecimal one!)

List names/descriptions (one name? plus one description for each of English, German, French, Italian, and Spanish, in that order)

int16(2) - Length of name (name_length)

string(name_length) - Name (stored as UTF-16 or some other two-byte Unicode encoding; this means the length in bytes is equal to name_length * 2)

byte(2) - unknown 2

int8(1) - Card count

For each card

byte(1) - unknown 3 (usually 0x00)

int16(2) - Card ID

int8(1) - Allowed number of copies (0x00 = Forbidden, 0x01 = Limited, 0x02 = Semi-Limited; sometimes other values)

byte(1) - null (always?)

byte(n) - unknown 4 (to end of file, normally 4 bytes?)
