Pokemon Z-A Shiny Stash Live Map

A Nintendo Switch homebrew application that reads the Shiny Stash from Pokemon Legends: Z-A in real-time and displays each entry's spawn location on an interactive map.

What it does

• Reads the Shiny Stash block (up to 10 entries) directly from game memory via Atmosphere's dmnt:cht service
• Displays an interactive list of all stashed shiny Pokemon with species name, Pokedex number, and spawn location
• Shows the selected Pokemon's spawn point on the corresponding map (Lumiose City, Lysandre Labs, The Sewers, The Sewers B)
• All other stash entries on the same map are shown as gold dots for an overview of your shiny locations
• Decrypts PKX-encrypted PA9 data and converts Gen9 internal species IDs to National Dex numbers

Compatible game versions

The application automatically detects the running game version and adjusts accordingly. Supported versions:

• 1.0.3
• 2.0.0
• 2.0.1
• 2.0.2
