Create content/Saturn and system/Saturn at startup. Route the default core system directory and menu BIOS preflight consistently, retaining custom paths. Patch Saturn's x86 code pools to use the SDK executable allocator and release. Keep cropped frames in core-owned storage to avoid resized lent texture reuse. Include the patch in core stamps, provenance and shipped notices. Two deliberate frontend patch blocks increase the expected count 232 to 234. Verification: bash tools/verify.sh, all five gates PASS, 96 tests. Evidence: evidence/saturn-runtime; replay with python3 tools/evidence.py compare evidence/. Console: 100s controlled gameplay with clean captures; final frontend repeats 100s boot/demo and exits0; explicit BIOS preflight passes. Settings restored.
