    Client 1.25.0 (first retail release)

    I was reading through UO98 forum and come to this thread A few tidbits | JoinUO Forums Guy called Kair uploaded an archive with all packets descriptions. It is really comprehensive :) and it contains description for 0x81 packet: 0x81 - Login OK --------------- Client->Server:No...

    Displaying jpg images ingame using a gump

    I don't think this is possible with regular client aside from patching client files. But maybe community clients such as OrionUO or ClassicUO can display html <img> tag in the gump.

    UOKR research

    I think that bugs were the main reason why KR was abandoned, and enhanced client uses old graphics. So, I wouldn't be surprised. Fidling with the bin data could be the way. Useful info about KR data structure can be found here: https://www.uodev.de/viewforum.php?f=66

    UOKR research

    Couldn't it be a bug in the KR client? I don't think we can get a packet log. Disassembly is probably the only way to find out (but I'm not that skilled).

    Client 1.25.0 (first retail release)

    I was trying all the flags :) 0x5D, 0xFF, 0xCC, 0x64, it doesn't work. The point is that this version of client doesn't know 0xA8 packet (otherwise it would be in the packet table). The login sequence must have been different in those old days.

    Client 1.25.0 (first retail release)

    Seems 0x5D is a client packet. Don't know how should I send it from server. But maybe I'm missing something.

    Client 1.25.0 (first retail release)

    I was playing a little bit with the first retail Ultima Online 1.25.0 release and found some info willing to share: The login client keys doesn't follow the known algorithm. I had to find them via disassembly: Login Encryption Key #1: 0xF1A372D5 Login Encryption Key #2: 0x3A1FD527 Otherwise...

    Wow, it seems you've managed a way to create gumps dynamically on the client side. Good work! Please keep us informed. I'm really excited to this.

    Hi

    Sorry to necroing this, hope it is not prohibited. I have found some info https://github.com/KonssnoK/ultima_online_misc/wiki/Hacking_SotA Personally I dislike the idea of selling ingame items. But the point is that the game itself (without this silly fundraising things) is not so bad and the...

    Map Converter (ML to KR)

    I have improved the conversion process. It is now more than 4 times faster (on my computer, it takes 30 seconds for trammel) and requires approx. 200MB RAM. Without fast mode it only requires about 40MB RAM. Also I have release the source code. It is now part of UltimaKR tools, you can find it...

    CoreUO

    Thank you very much for your feedback. I have encountered the circular dependency problem in the beginning. In order to prevent it, only launcher project can reference other projects and more important, all handlers (Handlers.cs) are made static. Under this condition, message project can pass...

    CoreUO

    Hello everybody, I would like to introduce you CoreUO server. It is my experiment to write server from scratch. Don't see it as a competition, because it really isn't. Writing a server from scratch is very time consuming. For now it only allows to move with character. Every other actions...

    After sometime, I'm back working on game encryption. I have followed instructions from https://www.uodev.de/viewtopic.php?f=66&t=5330&sid=88cdbfcb5ad4c57eb495435fe1765342 and result is strange. Like if I try client 10 times, it successfully decrypt at least one time, but it's totally random. I...

    I've decided to start from the beginning... so here is the first part: How to connect with UOKR (2.58.0.6) client First, we have to somehow change the IP of server. There is no login.cfg. We can find out what address the client is trying to connect: Now we can look into client.exe and try to...

    From what i know Enhanced client uses old CC graphic, but KR client uses it's own high resolution textures. This is why i think that KR is better and can bring new players. New players won't start playing a game with outdated graphics. You can run KR on Windows 10 with 4k resolution and it still...
