i don't understand the point.
Basically a lossless format work a bit as an archiver (winrar, 7zip) with special algorythm optimized for samples.
So a FLAC samples must be exactly the same as the original uncompressed audio file.
About playing a MP3/OGG on a 030. I remember i could play an MP3 on 030 but unfortunately as low quality (11khz, 8bit....) so i think it's better to directly download original module and play them natively on your miggy
