Problem with disk for PC game

I used alcohol to open up a megaman x8 ISO file and installed the game. the problem however is that whenever I try to run the game, it tells me that I have inserted the wrong disk. I used mount on device for both disk 1 and 2, but it still doesnt seem to work. Is there something I’m doing wrong here?

Edit: it also seems to say “Loading Alcohol device drivers failed! Emulation options and native driver interface of Alcohol 120% will not be available” whenever i load up alcohol.

What copy protection does the game use? Scan with Protection ID and let us know. Also, how did you make the .iso images?

What OS are you installing on, try downloading the latest version to see if you still have the same problem
