I’ve been following the nightly builds as much as I can and recently updated to the latest Android nightly release at the time of Monday (dated 2015-05-28) as well as the then latest GXP libretro core (2015-05-08). I was hoping I could play Mega CD titles with oggs without the subsequent audio coming out like white noise like when I last updated, but it seems the end result is still the same. I made sure the cuesheet was setup correctly and that it was identifying the tracks as OGG rather than WAVE. Do they have to be encoded in a very specific way or has it just not been implemented?
A real shame as I know the Windows port has been able to play oggs without a problem for ages now. Was hoping that certain support functions like this one would be ported across all platforms at around or at least as close to the same time as one another, not many months.
