How would i go about decrypting a game that crashes sothink swf decompiler? I already have tried using swfdecrypt, but it says "sorry something went wrong while recovering". I obtained the game using swf dump. The game loads up in swf decompiler, but when i try to search all .as files or when i try to look in certain .as files it crashes. is there a group of opcodes i could search for to nop out that would stop it from crashing, or am i just screwed? :?

it is as3, i have looked through it and i think i have found some bytecode that doesn't look right, i think it may be confusing the swf decompiler.
Code: [Select] 24 00 74 63it's a jump to nowhere. |

Just from what you wrote, it makes sense:
24 00 - pushbyte 0 74 - convert to unsigned int 63 - setlocal Missed a byte at the end. Translated into AS, it'd look like: _loc# = uint(0) Incredibly stupid, but nothing which should confuse a decompiler. Anyway, things that usually work for me is trying to compress/decompress and then run SWFDecrypt. Sometimes even UNSWFEncryptUNP (or something like that) works. If all fails, it's time to stress these neurons and base your hacks on the p-code and/or bytecode. P.S. an excellent reference of AS3 opcodes: http://www.anotherbigidea.com/javaswf/a ... tions.html |

wow, now that i look at that i really need to brush up on my opcodes lol, i was thinking 24 was jump when it is actually push, anyways i'll try what you said.
any links to that UNSWFEncryptUNP program? i've googled it but it results in a chinese or japanese wares forum that i can't read. :?: |
