Sent: Wednesday, September 23, 2009 2:54 PM To: submit@mamedev.org Subject: Tiny speed up in 'src\mame\video\neogeo.c' Hi, here is a patch against 'src\mame\video\neogeo.c' This patch give a tiny speed up in neogeo rendering and, IMO, gives the source code more readable. This is achieved by unrolling a loop in 'draw_fixed_layer' Doing so, the logic inside the loop is simplified, less arithmetic is performed and branches are avoided. Hope this helps, Best regards, Christophe Jaillet
