6.8.1 What is an area map

game, but usually the music changes as the scene changes. As music changes, the way the sound data is placed (how to use the 512KB sound memory) also changes, so the area map determines what kind of data is placed in the scene. Since there are only three types of data to be placed: "tone data", "sequence data", and "DSP program", an area map that determines where and in what size these three types of data are placed on the sound memory is. Also, when using DSP, "DSP work RAM" is required, so specify the location and size of DSP work RAM as well.

Normally, if there is two map information of tone data and sequence data in one area map, sequence playback is possible, but if you divide frequently used songs and SE etc. into different arrangements, memory efficiency and development efficiency will be improved You can build a good system.

As long as the game scene changes, the sound will change, so you need as many area maps as there are game scenes. However, the area map mentioned here is an area map viewed from the sound, so it does not necessarily correspond to the game scene one-on-one. If the sound of the game changes, the area map does not need to be changed if the sound is the same, and the area map does not need to be changed if only part of the sound data needs to be replaced.
