Hi Darkchylde,
First of all, thank you very much for taking the time to reply.
Now, this is strange, but your suggestion actually works!
Ah, I realise this doesn't sound quite right, so please let me explain:
I had already downloaded the "arf-arf" version, and, at Qbix's suggestion, had tried to launch the game using the hamgam z command. It seems that the music or the intro sequence -or some combination of both- was the source of my problems.
The thing is, the first couple of times I tried the hamgam z command nothing happened. Then, after reading your post, I thought I should give it it one more try and, what do you know, the game runs perfectly.
Apparently I was doing something wrong before, but the timing was...well, amazing, really.
Again, for taking the time to reply, and for some extra good karma that got Hammer of the Gods running, thank you 😁
