I’ve created Python & Pygame script that lets you walk around the overworld map of the original Legend of Zelda game on the 8-bit Nintendo. There are no monsters or levels or items; it is simply a walking tour. The Link walking sprite animation is implemented by my Pyganim module.
More importantly, this program does provide the raw map data the entire world map (something I haven’t been able to find on the web.) Getting this from the Zelda ROM is actually a pain due to the tricks used to store the map info. The game doesn’t store individual tiles and their XY location, but rather have one of three color schemes for the border and a color scheme for the center tiles. Even then, the game only stores columns of tiles, and then each room references which columns it uses. (You can notice the same columns being used in different rooms, even though their color scheme may change.)
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
