Transfer File Example - Nintendo GAME BOY Programming Manual

5.2 Transfer File Example

With sampling data consisting of a single sound with a sound number of 002h, the Directory data
would be the 4 bytes beginning at 4B08h, and the sod data would occupy the 6 bytes beginning at
4C3Ch. In this case, ensure that the score data begin at 2B00h. Starting these data at any location
other than 2B00h would cause a loss of program control. The sampling data (audio data) should be
transferred to the area between 2B00h and 3AFFh.

When using multiple sampling data items, also transfer the Directory and sod data specified for each
item in Step 2.
Note: Be careful not to rewrite the Directory and sod data used by the system.
