@@ -27,5 +38,4 @@ Entralinked has a built-in DNS server.\
 In order for your game to connect, you must configure the DNS settings of your DS.\
 By default, Entralinked is configured to automatically use the local host of the system.\
 This approach is not always accurate, however, and you may need to manually configure it in `config.json`.\
-If you receive error code `60000` when trying to connect, erase the Nintendo WFC Configuration of your DS and try again.\

+ * Game Sync ID generation process:
+ *
+ * Let's take example PID "1231499195".
+ * Start by storing both the PID and its checksum (35497) in working variable "ugsid".
+ * We do this by simply shifting the checksum 32 bits to the left: ugsid = pid | (checksum << 32) = 0x8AA949672FBB
+ * 
+ * Calculating each character is pretty straightforward.
+ * We just use the 5 least significant bits of ugsid as the index for the character table.
+ * Character 1: 0x8AA949672FBB & 0x1F = 27 = '5'
+ * 
+ * After each character, we shift ugsid 5 bits to the right. Since ugsid contains 48 bits of data,
+ * taking the 5 least significant bits each time gives us enough indexes for (if we round up) exactly 10 characters.
+ * If we take a look at the full value of ugsid (0x8AA949672FBB) in binary and split it into sections of 5 bits,
+ * we'll actually already be able to see the entire Game Sync ID in reverse:
+ * 
+ * Character:        'E'   'L'   'X'   'F'   'E'   'Y'   'Q'   'M'   '7'   '5'
+ * Chartable index:   4    10    21     5     4    22    14    11    29    27
+ * Binary:          XX100 01010 10101 00101 00100 10110 01110 01011 11101 11011
+ *                                           
+ * Adding all of the characters together gets us the Game Sync ID "57MQYEFXLE".
+ * 
+ * Reversing this process to retrieve the PID and checksum is very straightforward.
+ * Simply go through each character, find the index of it in the character table & left shift the total value 5 bits each time.
+ * If we do this with the Game Sync ID we just created, then it should give us back the value of ugsid: 0x8AA949672FBB
+ * To then retrieve the PID, simply do: ugsid & 0xFFFFFFFF = 1231499195
+ * To retrieve the checksum, simply do: (ugsid >> 32) & 0xFFFF = 35497
+ * We can then validate the Game Sync ID if we want to by comparing the checksums.
