From cec2bad823ffd06b216dc5858a99d67bc4936f69 Mon Sep 17 00:00:00 2001 From: Angelo Salese Date: Sun, 12 Oct 2008 22:07:28 +0000 Subject: [PATCH] Done most of the protection work for Double Dealer It appears to use a funky video register setting involving locations $8c1e0-8c1ef range for cards movements so it isn't playable yet. --- src/mame/drivers/ddealer.c | 331
