Memory sticks/cards don't suit N+1 separate save files the way Linux's filesystem does, so add an opt-in SAVE_DEVICE_DATA_RAW mode: settings and all save slots get serialized to JSON, concatenated, zlib-compressed, and framed with a magic/version/checksum/generation header, then read/written as a single blob through one combined platform hook instead of four. - PSP and Dolphin's SD/NAND backends write via a temp file + atomic rename, so a crash mid-write can never leave a half-written save behind. - GameCube memory cards have no rename or resize primitive, so they ping-pong between two fixed files instead, picking whichever is valid and has the higher generation counter on load. - Linux is untouched (still four separate JSON files); saveslot.h/ savesettings.h drop their now-unnecessary pack(1) now that nothing persists them as raw bytes.
