I've been sort of assuming the YM2151 is, at this point, pretty much good to go, but I noticed the current version of the FAQ mentions the final audio implementation is still up in air a bit:
Is it to soon to get some clarity here? Asking because I'm one of the composers for the FF-style RPG being worked on and the approach there has been to use the 2151 for the music, and the other options, whatever they may be, for the SFX. As a musician this isn't as ideal since I'd like to mess with the SAA1099 for sure But from a practical standpoint makes sense since we have readymade tools (Deflemask namely) we can use to compose music for the X16. It's not perhaps the most ideal but is the "best" option for now given it exists and there isn't (yet anyway!) a tracker solution on the X16.
All said, if there might be a chance the 2151 might NOT be used, that would have implications for the RPG. Obviously the X16 is still being engineered but the wording of the FAQ spooked a bit in this regard and thought I would ask.
I guess, in short, can we assume at this point that it is likely (though I understand not certain until the hardware is fully complete), that the YM2151 will be one of the sound solutions used in the X16?
