Overview
Play Mappy offline in a focused NES popup with verified controls and a local Loot Drill mode.
Play the original Mappy NES adventure directly from a focused Chrome toolbar popup. The game and its readable local NES runtime are packaged inside the extension, so the main experience does not download executable code or an emulator while running. Original is selected by default and fills the playable area. Press Enter to start, guide Mappy through the mansion, bounce between floors, recover the stolen items, and use doors to create space between the mouse police officer and the pursuing cats. Included features: - Original Mappy NES game as the default and dominant mode - Fully local readable JSNES runtime - Game-first 560 × 600 popup with no scrolling required - Verified keyboard guide for movement, NES A, NES B, Start, and Select - Session-only Favorite control with no persistent tracking - Working Share, PastPlay game-page, and PastPlay home actions - Local Loot Drill HTML5 mini-game as a clearly secondary mode - Stable Restart control for both the original game and Loot Drill Keyboard controls: - Arrow keys: move and steer while bouncing - X or J: NES A / open doors - Z or K: NES B - Enter: Start - Shift: Select Loot Drill is a small locally written HTML5 mini-game. Recover six items across five floors, use side trampolines to change floors, avoid patrol cats, and open nearby doors. It is not presented as a replacement for the original game. The extension does not inject content into websites, change browser settings, request Chrome permissions, or read browsing activity. External webpages open only after the user activates a clearly labeled Share, PastPlay, or Home control.
