Great, I'm glad you were able to get someone to rip it for you!
I don't think this will be added to the archives in flac form, though, since we try to save the format that the music was originally distributed in. For an Android/iOS game, it seems unlikely that the music was in flac or an uncompressed pcm format that you could make a flac from.
We'd prefer to have the original .adx files, before decryption with degod; vgmstream should be able to play those directly.
As a curiosity, I found some rip (quite old I think) where the frequency was at 44Hz, I estimate that because is a mobile game and are in constantly updated, so one day they decided to change the audio to 28Hz, is it possible?
