What GameDiary is

GameDiary records PlayStation Portable game sessions in the background and turns them into playtime statistics. Its PSP release has a kernel-mode tracking plugin and a user-mode application. It tracks native PSP games and PlayStation 1 classics running through POPS, then shows time played by game and across the library, session history, and activity graphs. The plugin also extracts game icons from EBOOT and ISO files. GameDiary includes web tools for visually editing sessions and combining backup files from multiple Memory Sticks or PSP consoles. To use those tools, export a backup.json file from the PSP app; the responsive web interface can be opened on a PC or smartphone. The interface supports English, Spanish, Portuguese, Russian, German, French, Italian, Japanese, and Chinese, with language detection based on PSP settings. Game data, logs, settings, and icons are kept in the Memory Stick’s GameDiary folder. Installation requires a PSP 1000, 2000, 3000, or Go with custom firmware, plus a Memory Stick or MicroSD-to-MS adapter. The project is free and licensed under MIT. Some homebrew may temporarily pause tracking intervals, and the tracker status overlay may briefly cause flicker or visual artifacts in some games.
