GameDiary is a seamless background playtime tracker and stats visualizer for the PlayStation Portable. It automatically monitors the games you play (both native PSP titles and PS1 classics via POPS), records your session lengths, extracts the game icons behind the scenes, and presents all your gaming statistics in a beautiful, modern, and fluid UI.

GameDiary operates in two layers:

• Kernel Plugin (PRX) - Tracks game sessions in real-time.
• User Application (EBOOT) - Reads and visualizes collected data.

Features

• Never lose track of your gaming hours.
• View total playtime, session history, and detailed graphs.
• Works entirely in the background without affecting game performance.
• Fully localized in English, Spanish, Portuguese, Russian, Japanese, and Chinese with automatic language detection based on PSP system settings.

Installation

Requirements:

• A PlayStation Portable (PSP 1000/2000/3000 or Go).
• Custom Firmware (CFW) installed (such as PRO, ME, or ARK-4).
• A Memory Stick (or MicroSD to MS adapter).
• The latest release of GameDiary (the App + the Plugin).

Installing the plugin (Tracker):

(PSP Go Users) If you are using the PSP Go internal storage, replace ms0:/ with ef0:/ in all paths.

1. Copy the GameDiary.prx file to your SEPLUGINS folder on your memory stick (ms0:/SEPLUGINS/ or ef0:/SEPLUGINS/ for PSP Go).

2. Enable plugin (ARK-4):

• Open ms0:/SEPLUGINS/plugins.txt in a text editor.
• Add the following line to enable tracking for PSP games:

psp, GameDiary.prx, on

• To enable PS1 games tracking also add the following line:

ps1, GameDiary.prx, on

• To enable Homebrew tracking also add the following line:

game, GameDiary.prx, on

2. Enable plugin (other CFWs):

• Enable for PSP games and Homebrew: Add to ms0:/seplugins/game.txt:

ms0:/seplugins/GameDiary.prx 1

• Enable for PS1 games: Add to ms0:/seplugins/pops.txt:

ms0:/seplugins/GameDiary.prx 1

3. Restart your PSP (or reset VSH).

Installing the application (viewer):

1. Extract the GameDiary app folder.

2. Navigate to ms0:/PSP/GAME/.

3. Copy the GameDiary folder there. Your absolute path should look like ms0:/PSP/GAME/GameDiary/EBOOT.PBP.

User guide

Boot up a UMD or ISO. The plugin silently detects the game ID, extracts the icon if missing, and begins tracking your playtime.

Run the GameDiary Application from the XMB. Scroll through the carousel to find your game, hit X (or O) to view your weekly and all-time playtime statistics.

GameDiary data is stored inside the ms0:/PSP/COMMON/GameDiary/ directory to keep your Memory Stick tidy.

• games.dat: Master database mapping game IDs to playtime statistics.
• sessions.dat: Session log for each game.
• config.dat: User-defined preferences. You can override system language strings or toggle UI features here.
• icons/: Cloned icons representing your played games, automatically managed by the plugin.
