Overview Of Creating Score Data; Setting The News System Working Environment - Nintendo GAME BOY Programming Manual

3.3 Overview of Creating Score Data

Original BGM can be played with the SGB sound program by transferring score data to the APU using
system commands.
Fifty-seven sounds can be used in BGM, and the score data can be up to just under 8 Kbytes in size.
The method used to create a musical piece is nearly identical to that of the standard Super NES.
When the NEWS system is used, score data is created using Kankichi-kun. When IS-SOUND is used,
score data created by an external sequencer are processed through MIDI and converted to create score
data supported by the standard sound driver KAN.ASM.
In addition the SGB score data format has been made openly available, allowing those using original
tools to create score data in this format.
In creating musical pieces, please refer to Section 4, SGB Sound Program Source List, when selecting
sounds. Please do not change the order of these source data.

3.4 Setting the NEWS System Working Environment

Working Environment Settings for the NEWS System
1. Rename the current sobox directory.
% mv sobox xxxxx
2. Create a new sobox directory.
% mkdir sobox
* SGB can use only specific sound objects. Thus, special SGB source data must be installed. A
sobox directory for SGB use must be created to prevent loss of previously installed source data
files with the same names as the data files to be installed.
3. Move to the sobox directory.
4. From the installation disk, install soread in this directory.
% tar xvf /dev/rfh0a soread
5. Next install the sampling data files (xxx.so . . . ) in this directory.
% soread
Executing the above command causes the sampling data to be automatically installed.
6. Create a new SGB working directory at any location.
% mkdir #####
7. Move to the SGB working directory.
8. From the installation disk, install the following files in the working directory: sgbt.asm,
sample.kan, check.kan, kankichib.hex, and kan.equ.
