I suggested the -c option as all your options were added to the commandline of dosbox
(the -c mount and the rayman.bat)

Ah, I got you;
dosbox c:\Rayman1\Rayman.bat -exit -fullscreen -c "CYCLES=9000" -c "MOUNT D Q:\ -t cdrom -usecd 0 -ioctl

Thanks again, but I wonder that you missed "=" mark in the command you recommended. Please post your idea specifically.

because the = is optionally ?

Yes, you are correct.
"=" mark in optional in the command line.

Ok, it worked !! Thanks for your kindness.
All my issues on Rayman are now solved.
