gbos.git/tools/gbjoin, branch master gbos - a tiny Unix-flavored OS for the Game Boy Color (kernel, shell, coreutils in C, RAM filesystem) https://git.sl0p.foo/gbos.git/atom/tools/gbjoin?h=master 2026-07-17T12:26:06Z tools: gbhub --daemon + gbjoin - interactive multi-Game-Boy networking 2026-07-17T12:26:06Z user user@clank 2026-07-17T12:26:06Z urn:sha1:584b19508b31f444ae02a974b96d1a50b8e650a2 gbhub gains a --daemon mode: instead of spawning headless emulators, it just runs the switch/router/DHCP and accepts link connections, handing each a lease from a pool (10.0.0.2..) and freeing it on disconnect. The link socket is made world-connectable so unprivileged emulators can join. gbjoin (no root) launches a *windowed* Game Boy and plugs its link into the running hub, with its own ROM copy so battery saves don't clash. So you get real interactive Game Boys on one network: term 1: sudo tools/gbhub --daemon term 2: tools/gbjoin # windowed GB -> 10.0.0.2 term 3: tools/gbjoin # windowed GB -> 10.0.0.3 (on each: SELECT for the OSK, then e.g. ping 10.0.0.3) Verified two GBs join the daemon and get distinct leases; routing is the same code path as the (already-verified) spawn-mode GB<->GB ping.
