Have you downloaded it from an abandonware site, unzipped it and ran it straight away? If so, the game will hang up at the memory scan bit because the game isn't properly installed.
Did you run the install program in order to configure your soundcard? Make sure you do so, as the install program also generates additional data that the executable file needs to read in order to run. If you don't do so, it will freeze at the startup like you mentionned. Oddly enough, this was the only thing I needed to do in order to run it under DOSBox.
This should work, although I suggest that you save regulary, DOSBox sometimes crashes when you finish a level. Although it doesn't happen that often, it always happen in those unwanted moments (like going through an entire tribe without saving, finishing the last level with only gold medals and BANG, DOSBox generates a warning error and crash, extremely annoying!). Apart from that bug, the game is pretty much all playable in the latest versions of DOSBox.
