Fixes game detection, which 5.4.5 broke — and makes Game Activity work.
- Games are identified correctly again. 5.4.5 changed how the helper
reads a game's ID and got it wrong, so IDs came back with the first four
characters missing. Anything that asks "which game is this?" was affected:
the process list, cheats, and play-time tracking. Reverted and checked
against two consoles. - Game Activity records play time. Verified on a real game: launches,
seconds played, and a live "playing now" marker. - Game Activity knows what you're playing right now. The screen asked
the console for the current game and the console never answered, so it
could not tell a session in progress from a finished one.
