More information: https://www.nesdev.org/wiki/Expansion_Port_Sound_Module While this is a homebrew device, it has already shipped to consumers in this manner. TODO (I'm not sure how to fix these issues myself): - [x] Switching from EPSM back to another peripheral (None or Family Keyboard) unloads not just the additional EPSM-provided audio streams, but seems to break *all* audio from the NES core. - [x] NES 2.0 cartridges can declare that they wish to have the EPSM peripheral installed by default (Extended Console Type 0x04), but I'm not sure how to hook this nicely from the pak data to the expansion port node. - [ ] Missing serialization, but this affects the Family Keyboard to some limited extent already, so... Not urgent at all. It has shipped to consumers, but the amount of software using it is still lacking. --------- Co-authored-by: Luke Usher <luke@usher.cc> |
