Hello there, since i'm using windows 8.1 i can't actually tell anything about win 10 in general, i had never used it and probably won't use it as well.. I had issues trying to play this game, but everything got fixed just by placing it to a C:/Dino/gameitself It helped me to launch the game, but i think it was more of an individual cure
Also, i know literally nothing about DOSbox, simply never tried it myself.. I'm using digital copy of the game, not physical, to be more specific As for me - we should all be using some "conditions" for the speedrun, so movies is a must, if your Videos folder is just not there, i can help you by uploading entire folder to file-sharing site, if the problem you have just stops the game from loading them in general - i can help as well, just need to know the exact case
