As far as I know, there are some kinds of sitelock, you may want to unlock it.
If you don't understand what I'm writing here, don't ask me, I'm NOT responsible for answering the question.

Tools:
Firefox plugin - HTTP Live Header
SWF Memory Dumper
SWF Decrypt
UnSWFEncryptUnp
Notepad
A professional Hex Editor such as Hex Editor Neo
SoThink SWF Decompiler
SoThink SWF Editor
Optional but useful: Apache Httpd Server

Here are some kinds of sitelocks, if it is obfuscated, you may find something similar, and you should know how to deobfuscate it using UnSWFEncryptUnp and SWF Decrypt. You need to hex edit the swf instead of using cheat engine.

AS2:
The Simplest one
Hashed Level Names

AS3:
The Simplest one
Binary in SWF

You have to apply AS2: The Simplest One first

Find these 2 functions in SaveFunction

---

? ? ? function getDataFile() {
? ? ? ? ? ? ? var _loc3 = String(_root.gcs + _root.gcid);
? ? ? ? ? ? ? var _loc4 = md5.hash(_loc3);
? ? ? ? ? ? ? return (_loc4);
? ? ? }
? ? ? function getLevelPrefix(num) {
? ? ? ? ? ? ? var _loc4 = String(_root.lpfx + num);
? ? ? ? ? ? ? var _loc3 = md5.hash(_loc4);
? ? ? ? ? ? ? return (_loc3);
? ? ? }

---

Now play through the original game and use Live HTTP Header to capture each level's name, and the name of a file that will load on each level.

---

? ? ? function getDataFile() {
? ? ? ? ? ? ? var _loc3 = String(_root.gcs + _root.gcid);
? ? ? ? ? ? ? var _loc4 = md5.hash(_loc3);
? ? ? ? ? ? ? return (_loc4);
? ? ? }
->
? ? ? function getDataFile() {
? ? ? ? ? ? ? return (%The name of file that will load on each level%);
? ? ? }
And
? ? ? function getLevelPrefix(num) {
? ? ? ? ? ? ? var _loc4 = String(_root.lpfx + num);
? ? ? ? ? ? ? var _loc3 = md5.hash(_loc4);
? ? ? ? ? ? ? return (_loc3);
? ? ? }
->
? ? ? function getLevelPrefix(num) {
? ? ? ? ? ? return (String(num));
? ? ? }

Now, Download the swf that always load on each level and all levels files, rename each level to 1, 2, 3...., place them in correct relative folder structure as it is in it server and you are done.

Open game swf with SWF Editor,
Search for binarydata, you will be brought to DefineBinaryData tag,
Right click and save as "original"

---

Edit with hex editor
you will see
XX XX XX XX (Old Binary Data) 00 00
Delete the first 4 bytes and the last 2 bytes of 00
Save it.

---

Using SWF Memory Dump, open the game, look for an approx. 200KB file, dump and uncompress it.
Do AS3: The Simplest One on this smaller swf.
Compress it, open it with hex editor.
Copy the first 12 byte of original and insert it at the begining.
You will see XX XX ?? ?? ?? ?? XX XX YY YY YY YY (here is your new binary data, it looks like 43 57 53 ........ )
Count the length of your binary data starting from YY YY YY YY and write it to ?? ?? ?? ?? in little endian

---

In the game swf, replace the whole original hex code with the whole new hex code.
Scroll to the begining of game swf, there is XX 57 53 XX ?? ?? ?? ?? ....
Count the number of byte of the whole swf and write it in ?? ?? ?? ?? in little endian.
Save it and it is done.
