- Fixed the actual reason saving never worked on any platform: saveWrite()
never stamped file->header/file->version before serializing, so every
written save file had a zeroed magic header and failed its own
validation on the next load. Confirmed via a manual write/load round
trip that this alone fully explains "saving doesn't work."
- Re-enabled saveInit()/saveDispose() in engine.c (previously commented out
under "Temporarily disable save code").
- Added SAVE.available + saveIsAvailable(), refreshed by every real
save/load/delete attempt. saveInit() no longer treats an unreachable
save medium as fatal to booting - it logs and continues, since a missing
memory card/stick shouldn't prevent playing.
- Hardened PSP's saveInitPSP() to actually detect a missing memory stick
(sceIoGetstat on ms0:/) instead of assuming success, and fixed
single-level sceIoMkdir to build the full PSP/SAVEDATA directory chain.
- Added busy-retry (CARD_ERROR_BUSY) and a not-mounted guard to Dolphin's
live savestreamdolphin.c path, extending the same handling already
backported into savedolphin.c.
- Added a "Save" entry to the game menu wired to saveWrite(0), showing a
clear message on success, on failure, and when saveIsAvailable() is false.
