This is a document with miscellaneous notes about the sound engines in various Sunsoft games. It doesn’t cover data formats, but for each game there is misc. info, like bankswitching, DPCM usage, and Init/Play (or other) addresses. For some of the games there is info about datas in RAM. (Including current address of BGM datas, which might help for those wanting to hack music).

There are comments based on comparisons between the different games, and theories about how much the sound programmers re-used or changed code between games.
