From d524be28c5933a9d7605955a2368212a31c72d16 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?In=C3=A8s=20Varhol?= Date: Sun, 15 Sep 2024 14:57:00 +0200 Subject: [PATCH] hw/display: Fix mirrored output in dm163 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit DM163 is an emulated 8x8 LED matrix. This commit flips the image horizontally so it's rendered the same way as on the hardware.
