Just an FYI - I haven't "failed" once at reversing anything out of the newer clients, just inferring that the amount of effort required (writing a VMProtect de-obfuscator) doesn't really seem worth it for the relatively small gains. If you and your dev partner feel that it's worth the effort...

Because it seems like no one has stepped up to release fully unpacked Themida and VMProtect stripped and de-obfuscated clients since I stopped (like a year ago). I'm not saying that others aren't capable of doing it, but if people are, then they're keeping it to themselves. Reversing anything...

I had plans to do this with my server too, but I sadly have so little time for MapleStory these days. I swear that I've wasted more than a whole year (as in more than 8760 hours) of my life just coding and reverse engineering :( So is the concept of your "backporting" just downgrading a higher...

Hey TigerXp4 can you please stop begging Im so need it I'm not some localhost making witch. Why not try to make it yourself rather than constantly asking me for it?

No worries. I can't remember exactly what I patched, but I know there was a bug in this client that made it crash when it tried to upload the last exception log. I think that was on client run though, not login to game server. Meh, either way if it's working then don't question the miracle :)

I'm using the v28_noaes.exe client that someone uploaded before. I've probably made some edits to it though, so just incase here's the download - You must be registered for see element. Relevant game login stuff (from my server, but I'm sure you can figure out what it should be doing :))...

Seems to work fine for me :) You must be registered for see element.

So far as I can tell, the encryption is exactly same code as 0.53. There are a few (really) minor implementation differences that might be enough to make it not match up, but the custom encryption and AES key are the same (starts 0x13, 0x0, 0x0, 0x0).

Pretty sure it either doesn't have the custom encryption, or it's different. I can try to reverse engineer the encryption function a bit later on.

LEN was patched at around v115 and I haven't made a working version since v12x. I would love to make it and release it to the public / sell a private version, but it's now almost impossible to reverse engineer the VMProtect'd stuff to figure out what's going on. It would take more time than I...

There's never enough going on to keep me entertained enough to stick around :(. Plus each time I come back and release some amazing new tool to help the scene it ends up making things 1000x harder (for everyone) than they were before I came back. Examples: I accidentally leak a packet...

v.28 localhost - You must be registered for see element. DXWnd - You must be registered for see element.

I'll just leave this here - You must be registered for see element.. P.S. I appreciate it's a few months after you asked for it, but I was bored :)

The earliest version of LEN was not packed nor protected in any way. This release is both packed and has virtualized functions. Here's the unpacked: You must be registered for see element. Also: You must be registered for see element. Also: You must be registered for see element.

This does not use LEN. It may have ripped some of LEN's code, but I can assure you guys it is not LEN. The DLL appears to be Delphi or BC++. LEN is written in C++.
