I *think* you should start again again 😀
Make sure you follow the 60 seconds guide almost to the letter and then install the game from within Dosbox and use the same mount/imgmount as you did when you installed.
The reason I'm saying this is because

i mounted e e:\ (another local Drive) just in case of system related issue

makes me suspicous that something is not mounted as it should be mounted.

Back again , i figured out ! i just made another replacement for these folders "fighter" and "bgnd" from MKTrilogy Windows Installation put them again into DOS installation Now GAME FULLY WORKS WITH NO FATAL ERROR! AND OF COURSE ALONG WITH MUSIC TRACKS ! yay FINALLY i Even tried feature "Audio CD" on/off in game opntion with NO problems Woohoo ! i'm gonna beat that SOB shao khan tonite 😁

Thanks guys much appreciated 😁 😎
