Neopets Mobile

Neopets Mobile does not refer to the 2021 interface of the website, but the 2006 flip phone application that has long been discontinued.

Attempts to reverse engineer the long-defunct API

TODO (The jars are all minified, but perhaps I can extract the API URLs from them and document what the application expects to get back)

The META-INF/MANIFEST.MF for the Nokia 6280 version specifies a Java version of 1.4.2_04.

The decompiler used is quiltflower: https://github.com/QuiltMC/quiltflower and the javax.microedition classes were copied from https://github.com/mcpat/java-microedition-libraries

Nokia 6280 V02.30.00 (en) Singtel

m.java contains two calls:

• http://npprod-singtel.in-fusio.com/data-np/
• http://npprod-singtel.in-fusio.com/singtel/check?session= followed by RecordStore.openRecordStore("data-i", true).getRecord(1) as a String if not null, else ""

The session check appears to return one of the following values, with anything else as a failure code of -1:

Response	Treated as ID
SUBSCRIBED	1
UNSUBSCRIBED	2
REVOKED	3
SECURITY	5

Nokia 6111

m.java contains one call:

• http://npprod.in-fusio.com/data-np/

Both

In b.java for the 6280 version and m.java for the 6111 version, there is code for the following POST request (taken from the 6280 version):

   private static final void a(HttpConnection var0, p var1, boolean var2) throws IOException {
      var0.setRequestMethod("POST");
      var0.setRequestProperty("content-type", "application/x-www-form-urlencoded");
      var0.setRequestProperty("connection", "close");
      if (a != null) {
         var0.setRequestProperty("x-up-calling-line-id", a);
      }

      DataOutputStream var3 = var0.openDataOutputStream();
      if (var2) {
         a(var3, "session=" + b);
         a(var3, "&");
      }

      a(var3, "client=NEOPETS/2.8");
      a(var3, "&");
      a(var3, "game=" + c);
      if (a > 0) {
         a(var3, "&");
         a(var3, "center=" + a);
      }

      if (d != null) {
         a(var3, "&");
         a(var3, "language=" + d);
      }

      a(var3, "\n");
      var3.writeShort(var1.a);
      var3.writeInt(8 * var1.a());
      var1.a(var3);
      var3.writeShort(255);
      var3.close();
   }
