Save State System

Service Overview

The Save State system captures complete emulator state including RAM, CPU registers, GPU state, and audio buffers. Unlike traditional save states, TruchiEmu's implementation includes rich metadata, screenshot thumbnails, and integration with your game library for seamless organization and retrieval.

Basic Save State Usage

1. Save State Usage

   Use Cmd+F1 to save to slot 1 and F1 to load. Loading is instant - the game resumes exactly where saved. Use F2-F12 for slots 2-12, or use the save state browser for higher slot numbers.

2. View Save State Browser

   Open the save state browser with Cmd+Shift+S to see all save states with thumbnails. Hover over states for metadata preview showing creation time, game location, and playtime.

   
3. Organize with Slot Banks
