&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{Wip}}&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;McRegion&amp;#039;&amp;#039;&amp;#039; is a [[Minecraft:mod]] created by Ryan &amp;#039;Scaevolus&amp;#039; Hitchman in 2010 that adds a new file format for storing chunks in [[Minecraft:Minecraft]]. McRegion was integrated into vanilla Minecraft as the [[Minecraft:region file format]], and Ryan Hitchman is credited in the [[Minecraft:credit sequence]] as &amp;quot;additional programming&amp;quot;.&amp;lt;ref&amp;gt;http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/mods-discussion/1346703-mod-mcregion-v5-optimized-saves-1-2_02#p2619453&amp;lt;/ref&amp;gt;&lt;br /&gt;
==Features==&lt;br /&gt;
The mod&amp;#039;s new file format functions the same way as the region file format. This is the [[Wikipedia:Binary file|binary file format]] for storing Java Edition [[Minecraft:chunk]]s from [[Minecraft:Java Edition Beta 1.3|Beta 1.3]] to [[Minecraft:Java Edition 1.1|1.1]]. Each file stores a group of 32×32 chunks called a &amp;#039;&amp;#039;&amp;#039;region&amp;#039;&amp;#039;&amp;#039;. The format took the place of the [[Minecraft:Java Edition Alpha level format|Alpha level format]], which had been in use since the [[Minecraft:Infdev]] development phase, where chunks were stored in individual files on the file system. The file does not begin with a [[Minecraft:wikipedia:Magic_number_(programming)#In_files|magic number]], unlike [[Minecraft:wikipedia:List_of_file_signatures|other file formats]], and begins directly with the header. The format has been superseded by the [[Minecraft:Anvil file format]]; however, the Anvil file format made changes only to the [[Minecraft:chunk format]] and changed the region file extensions from &amp;quot;.mcr&amp;quot; to &amp;quot;.mca&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
The McRegion format was adopted nearly unchanged, except for the addition of a table of chunk update timestamps. [[Minecraft:JahKob]] has claimed that this format is up to 7 times faster than the previous system.&amp;lt;ref&amp;gt;http://www.pcgamer.com/minecraft-dev-diary-new-block-magic-fiddles/&amp;lt;/ref&amp;gt; The difference in a world&amp;#039;s total file size between the Region file format and the Alpha level format is negligible.&lt;br /&gt;
