Detailed patch notes for Conquer Online, from version 2.0 to 3.0, and excluding patches that only add new servers, new temporary events or fix bugs. When targeting a patch, take the highest before a feature you do not want. Also, note that † denotes protocol changes, but only patches between 5016 and 5078 are identified because that's the range I personally target in COPS X Emulator. Later patches (above 5100) are a bit less exhaustive, because at that point, TQ were releasing a lot of daily quests, a lot of boxes and other pay-to-win content. So it would be quite bloated... I'm also less interested in those.

Yeah was used, I was toying with it. I think there is still a bit of leftover for items. Otherwise, take a look at the original COPS v6 release, or here is the commit that introduced Mongo, you may be able to restore a bit of the old code. ab31589b0e4be0cf7cb3103e8368bc87f8fa0e76.diff

You can try to edit the MFC resources directly in Resources Hacker. You won’t find them in GUI.ini

From what I remember, the old login layout was one of the rare GUI to be solely based on the MFC resources + code to position elements (i.e. it checks whether it is in 1024x768 and if so, move some elements).

Yeah you should be able to use the library as-is.

It's an old implementation, but it should do the trick: https://github.com/conquer-online/co2_core_dll/blob/master/src/IO/WDF.cs

Any kind of spoofing in general (there is a shitload of checks that are done client-side but can be bypassed). Think of things like reviving early, jumping further, jumping over walls, walking/jumping on invalid tiles, going through gates, jumping while transformed (i.e. in robot/golem), using other items then mets/DBs to upgrade in TC, etc. One interesting one is that most sources have fixed indexes for the NPC "pages, so you can bypass a lot of checks by spoofing the right index (instead of starting at 0). So for example, you can upgrade items in markets without doing some checks, etc.

You send the caster/attacker ID, and the casted position of the line skill (i.e. where they clicked). The client will compute the DDA line between the caster position (as known client-side) and the casted position (as received in the packet) to render the animation. No explicit direction is sent. This was likely added to Eudemon after the code bases forked.

Event_Server_Start does not exist in the Lua context (i.e. nil value). Make sure that if it is a C# function, it is properly registered/exposed to Lua. If it is a Lua function, make sure it is actually defined.

Yes, the view range is also hard-coded client-side. The client will discard out-of-range entities and remove them without the server telling it to do so. The server still has final say on which entities are shown or not, but it cannot exceed the client-side view range without modifications.

The soul source code is a decent base for money / item drops (excluding things that are specific to CO like mets, DBs, blessed items and such). There are minor differences, but it would be near enough for regular drops without reverse engineering the TQ bins. For the tasks / actions, these are used for "special" drops (like Pheasants dropping PK tickets and such). There is a death action that is triggered when a monster is killed by a player-owned entity (like a player or a pet).

For an offline CO experience, take a look at https://github.com/conquer-online/cops-serverless (but it requires C++)

There were multiple leaks around the patch 5065/5072/5095, but they are Chinese databases. Then, you have more recent leaks with English databases, but a lot has changed since then, so they are not always useful. Depends what you want to do with them. The database you see in my old source is actually from 4356 and in English, but it isn't public nor shared.

For really old client versions, TQ used UPX to pack the executable, which is often flagged by antivirus as an obfuscation method used by viruses. So, you can always unpack the executable. For patches around 5017-5065, some still get flagged even if not packed. At some point, there isn't much that can be done and the best is to recommend to all players to exclude the folder. As many are just using Microsoft Defender, you can normally run a PowerShell command in your installer to auto-exclude the folder.
