Converting 4 Disc PC games, to 1 DVD PC Game

[allegro16]

Hi, i opened data.tag in notepad, but only got this:

[TagInfo]
Company=Fox Interactive
Application=The X-Files
Version=1.00.15
Category=Games
Misc=

So, that's of no use..

I try some other things later today..

Thanks,

Allegro.

UPDATE

I opened SETUP.INS with notepad, and i think i found the call for the cd:

"
CD_INSTALL_PROMPTR–ÿ$
R–ÿb–ÿa
$
Ršÿb–ÿb›ÿ* bšÿA
ÿÿ! 2•ÿA
 )
(
2”ÿB•ÿA A
" pI •B”ÿA  R™ÿb
a AÒ 2™ÿR™ÿ/ b™ÿ! 2™ÿB ! 2˜ÿA / a XFiles#! 2”ÿB (
2”ÿB™ÿA B”ÿ" pF •B”ÿA ! 2—ÿA 
2”ÿB™ÿA
 (
2“ÿB—ÿA B”ÿ" pF •B“ÿA y R˜ÿA R™ÿB—ÿA
 R›ÿa
y "

Noticed the # after the word XFiles? Looks likes thats where the cd number is placed. However, if i change it in notepad and resave it (saved as SETUP.INS, All files, ANSI) (remove the # for instance) it seems to install, but after some time get the message "corrupted setup.ins" And install fails.

Tried with various other programs (Hex Editors, etc), but everytime get the error: "I:\XFILES\SETUP.INS file has become corrupted. Unable to load installation instructions. Error 704"
It looks like it should work (change the path it looks for) but there seems to be something that checks the integrity/checksum of the file. Even if i just open it an resave without altering it..
