From patchzyy/Wiicompiled 6f14bde (#244), runtime and translator parts only: - Keep KD and NCD devices available while networking is off; only IP and SSL need the network. - Run RFLiIsWorking's alarm pump in a private interrupt context so callback register writes don't clobber the caller, and release the alarm recursion guard before rescheduling. - Share one LR continuation dispatch per translated function when it has several continuation calls. The renderer half of that commit is left out: it conflicts with the stereo renderer, and upstream reverted part of it (e409d9f) for stutters. (cherry picked from part of commit 6f14bde26a4ed6390d4f18e1b3a9c1be6819d589) Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011tcyLz63pXjoYEwsFjfg8F
