I'm trying to run this game typed from the legendary Finnish MikroBitti magazine. It works with a real VIC-20 of the fellow who had typed it and kindly sent me the files, but with the latest VIC-20 core my IPS Dell loses sync and says it cannot display the image. Other VIC-20 games I've tested work just fine. How could I get this working? What could cause the problem?
The game actually starts and I can get to the menu but pressing F1 to start the game apparently changes the display mode or something like that and Dell loses sync
The prg-file is attached, if someone wants to try it out (it's in Finnish, though).
