NFS:Underground
 

I'm trying to play nfs underground using the exe file in the original disc.

Thus as always I created the image file(*.mdf) of disc 2 using alcohol 120%. From my understanding Underground uses safedisc 2.90.040 so I couldn't use daemon tools for emulating safedisc because it only supports up to safedisc 2.70. I tried using alcohol's safedisc emulation but doesn't work either.

How do I play Underground without using a fixed exe file?

It will not help you, but playing NFS Underground without a fixed EXE is possible with the Original CD in your CD-Rom-Drive !!!
