Hi,
I have just been trying this game on my machine. I completed the first mission and then the game asks for disk C - there is also a small screen glitch which leads me to believe it's crashed. It doesn't progress from there.
Specs:
STE - TOS 2.06 - 4MB
HDDRIVER 9.10 on CosmosEx.
I will try under TOS 1.62 and report back.
Same under TOS 1.62...
This is marked as C on adapts table - what means that is complete - someone played thoroughly. In 10 years since it is released did not get some problem report. And I'm sure that I played more than first mission when tested it.
So, it may be that something is not so reliable.
I recommend to go in HDdriver settings and lower it's RAM usage (it gives a lot when detects 4 MB).
On this page bottom is help for that: http://atari.8bitchip.info/GamexUsage.html (http://atari.8bitchip.info/GamexUsage.html)
