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
