- Cross-build against the Steam Runtime 4 arm64 SDK (build_linux.sh, cmake/steamrt4-arm64.cmake): the executable sits at 0x98000000 next to the game's 32-bit window, with the OpenXR loader and jsoncpp beside it (RPATH $ORIGIN); build_linux.sh also packs a release archive. - OpenXR on SteamVR: EGL surfaceless through XR_MNDX_egl_enable, the Frame controller profile (both names), a flick or a wrist turn as the Wii Remote's shake, the D-pad as look; the refresh rate goes to 120 Hz through vrcmd where the runtime offers only its current rate. - Timewarp in the app: SteamVR shows frames that arrive in time as they were rendered, so at 120 Hz every game frame stood still for two refreshes while the head turned. The game frame's eyes now go into a scene set, and every refresh composites the last finished set turned to its own head pose (timewarp.h, checked by tools/timewarp_test and by the simulator's PETARI_XRSIM_WARP); sharpening runs once per game frame; the pacing changes only after a new display period has held. - Fixes found on the way: libstdc++'s <cstdio>/<cwchar> against the MSL renames (compat.h), language archives a disc carries damaged (cook.py takes another language's), host allocations on the DVD and DSP threads, quitting without waiting on the game's threads, case of two include names. - ANLEITUNG-STEAM-FRAME.md: the player's guide in German.
