Arachnophobia is not a very common game. I had never even played it until a few years ago. The game uses a lookup sheet for it’s copy protection. I did buy an original copy from Ebay to get these sheets:

ELITE by FIREBIRD just seems to ADVANCE for 1985.
There was a few different versions with different copy protection.
Here in the USA one verions was GMA with extra tracks 36-40
Another version used Lenslock and a manual Symbol look up.
Here is that sheet to help you.

Die Hard 2 used a code sheet for it’s copy protection.
The game will ask you for the arrival time of a flight and here they are:
