Overview

Grid picker window for save state slots.

Displays up to 10 slots in a 2×5 grid. Each cell shows a PNG thumbnail screenshot, the slot number, and the save timestamp —or an “Empty” placeholder. Left-click a populated slot to load, click an empty slot to save. The current quick-save slot is highlighted with a distinct border.

Uses native Tk photo images for thumbnails (loaded via ‘image create photo -file`). Pure Tk — no SDL2.
