From: Paul Cercueil Date: Sat, 21 May 2022 16:52:47 +0000 (+0100) Subject: dfxvideo: Restore support for big-endian arch X-Git-Tag: r24~359 X-Git-Url: https://notaz.gp2x.de/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ae097dfb64926c50902b08b681cbf805b98e3751;p=pcsx_rearmed.git dfxvideo: Restore support for big-endian arch The hardware registers, emulated RAM or emulated VRAM are all in little-endian format. Therefore, each access must be done with one of the byte-swap macros, for the plugin to work on big-endian systems.
