Now that the working week is over, I've tested the crunched / compressed disk some more (see
post #25) and it works with the following configurations in WinUAE:
... A1200 (2MB Chip RAM only) but turn "Cycle-exact" off.
... A500, OCS / ECS, 1MB Chip RAM, KS 3.1 (though runs slowly).
@meynaf; I presume that when going through the code to do this port you came across the "Codes"? Is there only one to access "Mission 2" or is there also one for the "Epilogue"?
Would be cool if you posted these so that I can test and add to the "arctic.readme" file
