dumped Internal rom from an Oversea (English) region "Oriental Legend 2" cartridge confirming only the region byte changes in that case. [Jeremy Romine, Peter Wilhelmsen, Morten Shearman Kirkegaard]

Other regions, including Japan single PCB need confirming to see if there are further changes in those cases or not. As the Oversea version ignores the Card Reader MCU we can mark it as working, so New Working Machines Oriental Legend 2 (Oversea) [David Haywood, MetalliC, Jeremy Romine, Peter Wilhelmsen, Morten Shearman Kirkegaard]

+	Holographic Stickers
+
+	The IGS036 CPUs have holographic stickers on them, there is a number printed on each sticker but it doesn't seem connected to the
+	game code / revision contained within, it might just be to mark the date the board was produced as it seems to coincide with the
