	: Speaking of English.dat (and english2.dat), I noticed we haven't got any documentation for it. From what I can rememeber from a little C++ experimentation a while back, the language file simply loads each null-terminated string into an array of strings and the index for each string is used as the lookup value as seen in files like facil.dat and obdata.dat. I'm not sure if english.dat and english2.dat are loaded into one large string array or if they are in separate arrays. - [[User:NKF\|NKF]]		: Speaking of English.dat (and english2.dat), I noticed we haven't got any documentation for it.

			:: I think english.dat is used by geoscape and english2.dat is for tactical. And yes they are simply null terminated strings in an array. Though interestingly I've noticed that it seems to start at 1 and not 0 in some situations (still investigating this). I say this because the sequence matches what I expect except that the offsets are 1 greater than if the array was 0 based. Possibly a value is 'injected' before all this and contains the 0 slot. I guess we could alter one of the look ups to 0 and see what it comes out to.

Pi Masta: English2.dat Lookup table found!

2007-02-10T03:16:13Z

English2.dat Lookup table found!

New page

==English2.dat==
Hey I think I found the lookup table for English2.dat (or german2, etc) in TACTICAL.EXE. It's at offset 0x5F910, each entry is 2 bytes long. It corresponds with the entry in [[OBDATA.DAT]]. The index in obdata is the offset in this array of 2 bytes. Let me give an example:
(AT OFFSET 5F910)
7B 00 | 7C 00 | 7D 00 | 7E 00 | 7F 00
0 1 2 3 4

0x7B (or really 0x007B) is 123, which in English2.dat is Pistol

For further Proof:

(OFFSET 5F944, 52 bytes from begining, so 52/2 = 26)
95 00 | B0 00 | 00 00 | 00 00
26 27 28 29

0x0095 = 149; english2.dat[149] = 'Stun Rod' (OBDATA[26] Is info for Stun Rod)
0x00B0 = 176; english2.dat[176] = 'Electro-flare' (OBDATA[27] is info for electro-flare)
OBDATA[28-30] are 'empty' unused obdata slots

(OFFSET 5F94E, 62 byte from begining, so 62/2 = 31)
AE 00 | AE 00 | AE 00 | 96 00
31 32 33 34

0x00AE = 174; english2.dat[174] = 'Corpse', Obdata[31-33] are all corpses (with different armor)
0x0096 = 150; english2.dat[150] = 'Heavy Plasma', Obdata[34] is info for Heavy Plasma
