Reverse of L2LogD.exe is finished, all classes are defined, except for Memory allocator package. I'm exporting code and working to make it compile. I think, it might take next month or two.

This is in private repo so far, so PM me if you contributed, and want L2LogD sources earlier.

 

If someone wants try to reverse memory management unit - you are welcome, I can share IDA file (be sure you have some reputation, though). Otherwise, I think, I will use some 3rd party allocators (they are used for std and IO buffer pools in L2LogD)

Two branches were added: with changes for C1 and C4 client https://bitbucket.org/master_toma/lineage2-c1-harbingers-of-war/branches/

Tested with C1 Client and  C1 SINA server + C4 Client and l2server_fyyre.exe server.

Thanks smeli for help.

I found "hidden" feature in LogD.exe - performance monitor. perfmon.ini is needed to activate it. It checks for RAM usage, Processor's usage, etc, and adds results to DB

Original L2LogD.exe has problems with x64 PC (which I have). I'll fix it, but meanwhile could anyone check it on x86 PC? perfmon.ini file to be added in root, near to L2LogD.exe:

[PerfMon]
CheckPerfMon=1
Count=1
Interval=6000
Memusage=1

Perf1Title=Title
Perf1ObjectName=Processor
Perf1InstanceName=0
Perf1CounterName=% Processor Time

performance monitor feature not hidden, it just not working cause of bug

i fixed this bug via extender on server.exe

also it is on logd, cached, npc - everywhere the same bug

I'm working on BCP (bulk copy from log files to MSSQL server) feature from LogD binary. It has quite sophisticated logic, related on files from chat/ and in/ directories.

I would appreciate, if you could sent those log files for test purposes to master.toma87@gmail.com. I want to test different combinations. Ofc, all those data will be used confidentially

L2LogD source code will be ready on weekend. There will be also some minor but important fixes for PerfMonitor, ports, etc.

 

About 90% of binary is decompiled. However, I need some help here. What is not finished yet:
1. Memory allocator units (you have to be skilled enough, to define structures and provide proper names to members, variables and methods). 
2. More easier task. L2LodD.exe has 3-5 methods for parse item.dat, skills.dat, etc. I didn't touch this functionality yet, left it for volunteers. It shouldn't be complicated, since structure of those files is known, so it might be a good task for beginners (ofc, you have to be skilled in c++ still).
 

If you want to help me, I could send you my IDA database for L2LodD.exe. It contains all structures, renamed methods, etc. 

 

I will share sources (L2LogD and other in future) for all, who take participation.

During testing L2LogD, one more fix for origin L2AuthD.exe  was added:

https://bitbucket.org/master_toma/lineage2-c1-harbingers-of-war/commits/a7b736d7641348e7592e25c2018db5b338a6e5fc

 

Now L2AuthD.exe sends proper DB audit type for L2LogD. Looks like this bug in C1 AuthD was due to some incompatibility.

    • Thanks for the collection and the free advertising! These files have been in the public domain for a long time — you just saved people the trouble of searching. A true fan. 😄 Just to clarify for everyone reading: these files have nothing to do with this topic. They are 10+ year old builds, and since various third-party modifications exist in the wild, we cannot guarantee what may have been added or changed in those versions. Use them at your own risk. We have absolutely no judgment toward those who are on a tight budget and can't afford our current builds — these old shared files might genuinely help you get started. Just use them carefully and at your own risk. And please don't judge developers for the mistakes they made early in their careers — every developer goes through stages of growth, and what you see in those old builds is simply a snapshot of where we were back then. We've come a long way since. If you're interested in our older builds, we have a dedicated thread for that with significantly reduced prices — very accessible for any budget. We have also recently resumed full technical support for legacy builds, handled by a separate team that doesn't interfere with our private development direction for larger projects. You can find our legacy builds here: Our OLd L2-scripts Packs Actual revisions Our current private sources are a completely different story — which is exactly what this thread is about. Too bad all your time goes into collecting other people's old code instead of developing your own project. Though judging by "L2MID is currently offline, we will come back soon in 2026" — you clearly have plenty of time on your hands. 😉
    • SHARED alreaxy! Are these files yours? https://fex.net/ru/s/kdop2z4
    • You asked for examples of coping projects, we provided them, you asked for feedback from our clients, some of them wrote their reviews on the same mmodev, what else can I prove to you? you just asked your friends from mmodev to write nasty things, they have never been our customers and never will be, because they are used to downloading only free products and hacking it. You just don't respect the work of others, this is the conclusion that can be drawn from your inflammatory topic on mmodev, where there are many people who once could not buy our assemblies or whom we kicked out of work or for some other reason. But you are completely wrong and you are behaving very lowly. But let it be on your conscience. Good luck, keep busy with your project, and don't interfere with others.
    • I will never use L2J as the basis for my project but what i saw in MMODEV was enough for me. GL
