 As a rule of thumb:
-  * RAM starts at 0x40000000
+  * RAM starts at ''0x40000000''
-  * There's a mirror of RAM available at 0x00000000
+  * There's a mirror of RAM available at ''0x00000000''
   * Size of RAM depends on model.
-  * 0xCxxxxxxx and 0xDxxxxxxx are ranges where most devices live
+  * ''0xCxxxxxxx'' and ''0xDxxxxxxx'' are ranges where most devices live

 In disassembled code those may look like:
 <code>
+// src holds address of data source in rom
 src = &DAT_e101ced8;
+// loop reads src, writes to dst and increases both pointers by 1
+// as long as "end" destination address is reached
 for (dst = &DAT_00004000; dst < &DAT_00023770; dst = dst + 1) {
