bnetd is compatible with starcraft remastered. i'll update my blog as i continue to investigate using an internal server. internally nothing important has been broken from 1.19 to 1.20.6 so far.
the game is usable but profiles, friends, MMR, and the right window for league and MMR and game stats is broken in the Ranked menu.
using Wireshark to find the proper IP addresses and what to insert where, i have successfully forwarded a clone of Fish Server from April 2017. the "^^" bot does not work and stats are not recorded, but that is because i have not completed a full setup. it is a secondary computer running Arch Linux.
this was achieved by modifying the hosts file in Windows. this will break all Battle.net function until you remove it from the hosts file. alternatively if you have a server grade modem to do this for you. but this is very specialized equipment.
i have not figured out matchmaking to a concrete solution, but Wireshark is make me believe the following:
1. matchmaking can be simulated in bnetd with future modifications
2. matchmaking has a unique IP address, where users are in a pool. this pool is a web of users, and two users with lowest possible ping within a time-dependent-expanding MMR threshold is decided and removed from the web, to be placed together.
3. the game marks a win and a loss on the respective users. this is entirely broken on bnetd
my blog will be expanded much much much further as time goes on. but my investigation has concluded why Fish Server did not support matchmaking and that it maybe easy to forward a server from 1.16.1 to remaster. perhaps iccup?
maybe an executable with a button to click enable-disable hosts modification should be made to a Remaster third party launcher for servers. this will break all Battle.net functions. including the website in your browser.
