Conversion is for multi5, for other versions here is manual steps to do so. (This is for advanced users, maybe someone wants to write conversion for other versions based on this)
get iscab, use iscab in my conversion for example
1) make list.txt with command
Code:
ISCAB data1.cab -lx -i"list.txt"
notice
-lx instead just
-l, this will list ALL files, most importantly IPS files
2) Extract IPS files only
3) Edit IPS files with notepad and add
ID_DISC2=Please insert disk 2 that contains the file data3.cab.
This would give window with title "Setup Needs The Next Disk"
and text in window "Please insert disk 2 that contains the file data3.cab."
without error
Instead with window with label "Setup Needs The Next Disk"
and text in window "ID_DISC2"
and error before that
4) Run add and replace command to add modified IPS files back to cabs
Code:
ISCAB.exe data1.cab -a -i"list.txt"
