Parchment (specifically the IFDB auto play-online) appears to break on the split-screen approach taken by scott2zil. Notably, although the game loads fine to the generic splash screen, when the player hits enter and the split-screen begins, the screen goes blank.
Regular ratty old frotz doesn’t seem to mind the split-screen approach. Is there something unique and exotic that @heasm66 has overlooked in his split-screen approach? Or is this an interpreter-side problem?
