doing some ICQ research and I found that LICQ's homepage is still online, with zero hint that it hasn't been updated in 11 years:

HOWEVER they used frames and an imagemap for navigation, and the internet archive didn't get the image. which makes navigating it a bit of a pain

@yuki it works with the later versions of ICQ, which were basically just ICQ-themed versions of AIM. So it's not what I'm looking for

got as many pages from there as I could (one is missing, the chat one), and got this for v5 info:

and the v2 spec is here: https://web.archive.org/web/20010126060900/http://www.d.kth.se/~d95-mih/icq/spec/v2/icq091.txt

apparently v3 never was really used, so the important versions are v2, v4, and v5.
I think that ICQ 99a/b used v4, ICQ 2000 used v5, and previous less common versions used v2/v1.

well ICQ99 seems to work on windows 10, so that's good. Sadly I can't register my ICQ number.

fun fact about this era of the ICQ protocol: It's apparently entirely UDP based, and I think it does UDP directly between users as well, rather than the server.
In other words, it's exactly the kind of internet program that only made sense in 1996-1999 before NAT was a widespread thing

@foone
... Are you planning to relaunch ICQ with a new server as a service for anyone who still has a client?? -
replied to DHeadshot's Alt last edited by
@ddlyh thinking about it yeah. specifically for the 1999-2000 clients, before it became AIM-flavored

replied to Foone🏳️⚧️ last edited by
their were proxies almost immediately, which used a local program that talked over HTTP to a remote server that then did UDP to the target (or their proxy) because any NAT, firewall, or proxy situation completely broke this

why doesn't my "gaming laptop" have wireshark already installed. this system is barely usable
-
replied to Foone🏳️⚧️ last edited by@foone it used a centralized server for identity and finding clients and then established a direct p2p connection between clients (that could be trivially spoofed)

a computer needs a hex editor, packet capture, Good text editor, SSH client, ghidra or ida, decompilers for C# and java, C compiler, pythons (2 and 3), binxelview, Dependencies viewer, DOSBox, UNP, at least one unity unpacker, debugger, relative-searcher, yychr, and emulators for at least 12 consoles & home computers.
otherwise it's just a toy, like a Nintendo.
