From 593a1cdd66ac83c1cefdd4cc5dd6338006fc202c Mon Sep 17 00:00:00 2001 From: BALATON Zoltan Date: Mon, 9 Jul 2018 19:02:36 +0200 Subject: sm501: Update screen on frame buffer address change When the guest changes the address of the frame buffer we need to refresh the screen to correctly display the new content. This fixes display update problems when changing between screens on AmigaOS.
