I have now tested the "small table" bitwap with a 320 kbps file, and it worked just fine on a player, so now Recorder tests could be of interest.

I've also looked a little on an assembler version, and I believe it would be possible to write more efficient code (like half the size or so, compared with the output from GCC 3.1.1), but I'm not familiar enough with embedded assembler in GCC (or SH1 assembler, for that matter) to complete it. Some stuff must be in r0 AFAICS, which complicates things.
