Navi Customizer Programs - Compression Codes
To enter these codes, have the desired Navi Customizer Program highlighted in the Navi Customizer screen. Hold the Right (->) button on the D-Pad, then enter the 10 button code (Composed of different combinations of the buttons A, B, L and R) for that NCP to compress it. Once compressed, the Navi Customizer Program's size will be reduced by one block, or square. Only non-textured programs can be compressed (AutoRun cannot be compressed either), and inputting the code again will decompress it.
