Re: Fortress Scrolling
Oh I did quite a few including:
Chuckie egg (you can find this on bagshot row)
Citadel
Galaforce (I even rewrote this in c#/opengl - completely works - pixel perfect conversion, just no sound)
Knightlore
Jetpac
Wizadore
If I feel generous I may even stick them online one day

The easiest way to get a cable in my experience is just get a modem lead from the beeb, 5 pin domino to 25 pin rs232, then just plug that into a pc null modem lead. 25/9 pin to 25/9 pin. No soldering needed
