+# gc-pedometer-emulator
+
+Game Boy Advance homebrew designed to emulate the Inrou-Kun, a GameCube pedometer.
+
+## License
+gc-pedometer-emulator is Free Open Source Software available under the 2-Clause BSD license. See the LICENSE file for full details.
+
+Background images were taken from Public Domain sources.
+
+## Overview
+
+The Inrou-Kun worked exclusively with the GameCube title Ohenro-San: Hosshin no Dojo. To use this homebrew ROM, copy the file to an appropiate flashcart, then attach the GBA-to-GCN Cable (DOL-011) to the Game Boy Advance. Finally, attach the cable to Controller Port 4 of the GameCube or Wii system.
+
+From the Main Menu, select "Edit Data" to edit information the Game Boy Advance will send to the GameCube. Use the D-Pad to edit specific entries (Up/Down changes values, Left/Right edits specific positions of certain values). Press the A button to move down the list, and press the L or R triggers to switch between pages. When finished, press the B button to return to the main menu.
+
+To actually send data to the GameCube, select "Send Data" from the Main Menu. Only when the Game Boy Advance displays this screen will the ROM emulate the Inrou-Kun pedometer. The process is automatic. Press the B button to return to the main menu.
+
+## Compiling
+
+This ROM requires DevKitPro and DevKitARM to build.
