Detailed Description

Tilemap structure for SNES tile-based graphics management.

The Tilemap class provides comprehensive tile management for ROM hacking:

Key Features:

• Atlas bitmap containing all tiles in a single texture
• Smart tile cache with LRU eviction for optimal memory usage
• Tile metadata storage (mirroring, palette, etc.)
• Support for both 8x8 and 16x16 tile sizes
• Efficient tile lookup and rendering

Performance Optimizations:

• Hash map storage for O(1) tile access
• LRU tile caching to minimize memory usage
• Atlas-based rendering to minimize draw calls
• Tile metadata caching for fast property access

ROM Hacking Specific:

• SNES tile format support (4BPP, 8BPP)
• Tile mirroring and flipping support
• Palette index management per tile
• Integration with SNES graphics buffer format
