openbv is early. The game runs and plays locally; online play doesn't exist yet.

Works

Start-up: the RndLabs intro and every main menu page (News, Profile, Game Browser, Host, Map Editor, Options, Credits), in openbv's redesigned look: 16:9, flat panels, one accent colour, the Rubik font. The game renders at the window's 16:9 size (1920x1080 by default); gameplay is the original's.
Settings: bv2.cfg and bv2.db changes saved in gasm storage.
Hosting a game: the server in the same process, the client joining it (tried with free for all on CTF-Daivuk; the other game types and the map rotation not yet).
Playing on a hosted game: spawning, moving, weapons, projectiles, particles, the HUD, the minimap, the console.
Sound: effects (2D and 3D) and music.
Keyboard and mouse as DirectInput read them; the first gamepad's sticks and triggers.
The browser: /play/ runs the same module on WebGL 2, with the data from the site (cached after the first visit) and the settings in the browser's storage.
Determinism: identical video and audio hashes on gasm's native and Node runners and in the browser player (tools/web-play-test.mjs: the menu and a hosted game, played).

Online play. Hosted games are reachable by the game itself only (gasm guests can't listen). The openbv server (Go, many sessions, an admin page) is in progress.
The Game Browser. It needs a master server; the original one is gone, and the openbv server will take its place.
LAN search, server pings, remote admin. They used baboNet's peer-to-peer UDP, which has no transport on gasm.
Gamepad buttons. Only the sticks and triggers are mapped.
The Prozac mod's data runs with openbv's font (Prozac ships fonts/font.tga where the game loads fonts/babo.tga; openbv's own font covers both); the rest of Prozac's changes to the game aren't ported.
The HUD's redesign. It is laid out for 16:9 but keeps the original's look for now.
The account server (profiles, friends, clans, stats) is gone; those requests fail as an unreachable server did.
