WC Hakkers et al demo disk

Demo/intros from the late 80:s/early 90:s.
Found among some dusty MSX1/SV328 disks. Some intros backported to MSX1 from SV328.
And yes, the WC HakKers (Wallsta City Hackers) name was intended as a joke but got stuck.
I think there's some problem with one sub-menu but I didn't investigate because I got bored.
