Getting a very old client to run

it works for me , client return an error but it continue to load so.. Its just matter of time to get everything to work , dont think you are only one who can do it ;)

If you using wrong opcodes client will crash immediately or will stuck .
I will check that out in a free time. I need correct opcodes, structure will be matter of time cause joymax mostly change data type byte>word and so on. Only time its needed to research on this. You can get opcodes list from sro_client i have tool to make it auto but it wont work (it seems too old client) so you have to take opcodes manually from sroclient via ollydbg.

Nah
I tried different opcodes and the Client doesn't crash
It just sends the keep-alive packets and that's it

correct (no error) characterlist:

Creator.Append "0201"
Creator.Append "01" '# of characters

PacketsSender Creator.ToString 'sending to client and adding size of packet

Let's create a site with all documentation of all the packets so zeteris can't be all like
hurr durr I'm the only one who got it working durr

I love the atmosphere of this thread, and I love how zeteris doesn't want to give something stupid as this out. This tells me a lot about you as a person zeteris, I know people who would give much much more than you could ever give out, just for a friendly question. But yeah, I can understand you, it's not only your fault if it wasn't for all those leachers...

It's clear that this community is hopeless, unless something big changes the complete mentality

I have used zszc packets to reconstruct old structure(this is structure of zszc packet) , there is much points where can be a differences between this packet and beta needs to research. Opcodes are 100% fine(i took them from client via olly).

Remember character list difference ?:
thats how it looks at BETA CLIENT:

I still dont know what it means , if someone of you know whats mean those packets write about it, its difference wich will appear in init game packets too for sure.

Hi guys,
well i never used olly and i am too lazy to look for tutorials :D but is it right that this is the opcode list of this client?

found about 129 of them...

ah and i wondered a while ago if someone have such an old beta client :D

Yeah those are the packet opcodes.

I have tryed in last nights to reverse entering the game packet but i didnt success fully with it, i stuck on the end of loading with an error, when i have fixed this error client close itself(idk why yet). To make it to work you need to know zszc packets well and much time to test it out, zeteris made bot for zszc so he is at better position than me.
Currently i have no time to sitting on this so i hope someone of you will keep trying and success with it , i have to finish coding statuses on pvp in my SSE project.

And another news its i will make website with all packets documentation (opcodes lists , packets structure descriptions and so on ). I have base from last 5 years , i hope you will like it.
+ I will relase sse walker and it will be open source . Its my help for real silkroad online fans.

Well zBot wasn't created for zszc. I just have many logs from different sro versions, so I can compare them.

just spitballing but did you change the region? It's definitly not the same as zszc ones. In zszc the jangan area would probably be something like 168, 98. Just like in all the new versions. But in this one it's all china only based so to spawn in the grassland of jangan you can use:

X Section: 78
Y Section: 50

I got these section values from the minimap so i'm pretty sure that these are working. Also I picked an area outside jangan and without mountains ect so you don't spawn inside a building or something so any xyz position should be fine.

Well like I said just an idea which you might check.

I think about a formula to calculate xpos in game.
Thats may be a problem.
For new version is:
Creator.Append Inverse(Float2Hex((DaneGracza.XPos - ((DaneGracza.xsection) - 135) * 192) * 10))
and 135 mean the center of the map on x.

I took coord of npc tp in Jangan
168-135=33
76-33=43
So maybe 43 is a section of the center of the map on x in old client.

Creator.Append Inverse(Float2Hex((DaneGracza.XPos - ((DaneGracza.xsection) - 45) * 192) * 10))

Well, I've took sectors from minimap too, gonna check the formula today ( I'm at school right now ), because old one isn't working. It shouldn't be so hard, just need to find correct values.
