Player usernames can be encoded and decoded as a long with the following methods:

public static long encode_37(String s) {

== '''Packets''' ==
|
|
The packet opcodes are unchanged from previous revisions, presumably this was before the protocol was being regularly modified to deter the developers of bots such as [[AutoRune]]. The payload/structure is quite similar to most other RSC revisions.

Notes:
|
|
|
|
* "ranseed" does not seed anything. RSC135 does not use ISAAC ciphering. It is an applet parameter or read from uid.dat. Presumably, it was used to identify players connecting from the same computer.
|
|
* Opcodes marked with * are preceded by 215. |
