Record PPSSPP save-state crash comparison on console

Browse Source 
10x with 8x MSAA still faults after loading the affected state. Balanced defaults and the saved 6x/MSAA-off profile pass repeated loads and a save/load round trip; 6x/8x and 10x/off controls also pass.

Evidence: evidence/ppsspp-balanced-state-run/. Verified with the isolated console harness, format/evidence gates (54 captures), and git diff --check. Raw console captures and backups remain ignored.

**God of War: Chains of Olympus (PPSSPP):** a user on firmware 5.02 reported an
intro crash at 10× and working play at 6×. Their logs show 10× geometry, 8× MSAA
pipelines and a null-pointer fault. The new default uses 6× with MSAA off to
reduce rendering cost. The logs do not establish the underlying crash cause;
the new profile still needs a console regression run.

A subsequent **Ghost of Sparta** console save-state test still reproduces the **null-image
fault at 10× with 8× MSAA** on the balanced-default build when those saved
settings override the defaults. The same state passed repeated loads and a new
save/load round trip at 6× with MSAA off, 6× with 8× MSAA, and 10× with MSAA off.
Each passing run lasted 80 seconds and exited normally. This verifies the
balanced profile for that reproduction; it does not fix the underlying image
creation failure or establish stability for every game. See the
[console test record](evidence/ppsspp-balanced-state-run/).
