Out of convenience, bytes are written using the hexadecimal base (any values using this will be noted with the prefix 0x), rather than an inconvenient succession of eight bits using the binary system. As you can see, it gets long and impractical very quickly.Įverything in game ROMs - be it programming, graphics, sound, text, assets, and anything else - is written in bits (zero or one), with each group of eight bits called a byte. If this sounds too complicated, you can load Calculator in programmer mode to do conversions between decimal and hexadecimal. Typically, hexadecimal numbers are written with the prefixes 0x or h so that they are not confused with decimal equivalents (e.g., 0x10, decimal 16). On the other hand, the hexadecimal base is base 16 and goes in the following sequence: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A (a single 'digit' meaning ten in decimal), B (eleven), C (twelve), D (thirteen), E (fourteen), F (fifteen), then finally 10 (sixteen, (1 * 16) + 0 or (1 * 16^1) + (0 * 16^0)), 11 (seventeen, (1 * 16) + (1 * 1)), 12 (eighteen, (1 * 16) + 2), and so on. The number ten can be mathematically represented in decimal as (1 * 10) + (0 * 1) or (1 * 10^1) + (0 * 10^0). Our normal counting system uses the decimal base, or base 10, and goes in the following sequence: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and so on. 5.11 Super Mario World 2: Yoshi's Island.
