Converting 4 Disc PC games, to 1 DVD PC Game

[allegro16]

Hi,

I noticed this topic today, cause i'm trying to backup the 7 disc The X-Files Game to 1 DVD-R.
I thought it would be easy, but none of the methods i tried seemed to work. (The Virtual Drive things sounds ok, but not what i had in mind)

I just thought it would be possible to just merge the 7cd's to 1 DVD.
I tried 2 things:

1.Use IsoBuster to extract the cd's to to an empty folder on the HDD (the folder has the name of each cd, so "XFILES1", "XFILES2", etc. Then include the autorun.exe and inf. (So folder contains files autorun.exe, autorun.inf and folders XFILES1 until XFILES7)
Burn it to DVD.

2.Create 1 folder, XFILES. Extract each cd to that folder with isobuster. (So no XFILES 1 to 7 but just the contents of all cd's.
It does not overwrite anything important, because most of the cd's consists of the same movies/audio (same size and dates, etc), only a few things differ and that is copied to the folder without any problem ofcourse. Only cd1 an7 do contain a lot of other data, but it doesn't overwrite anything.
Then burn it to DVD.

Both methods seem to work, but after a while it does ask for the next cd..

The main content of the cd's: (only folders/files marked * are present on almost all cd's.)


DIRECTX
GRAPHICS
MEDINST
MININST
QTW
XN*
XV*
XS*

CDICON.ICO
LAYOUT.BIN
SETUP.BMP
SETUP.INI
LANG.DAT
OS.DAT
SETUP.INS
SETUP.LID
NAV*.NMV*
README.RTF
AUTORUN.INF
DATA.TAG
AUTORUN.EXE
SETUP.EXE
_INST32IEX_
_ISDEL.EXE
_SETUP.DLL
_SYS1.CAB
_USER1.CAB
DATA1.CAB

I know a DVD version exists, but i couldn't find any info about it (the differences) I guess they simply removed the call for the next cd. But what file to crack or patch and how? Most are too big to open in Notepad..

Any idea how to get it to work? (Just like an original DVD or cd without the need to switch cd's??)

Thanks,

Allegro.
