Hi,

I just bought a compatible mp3 "cd player". It can play "MP3 CD", but I
have
not much idea about such thing.

Usually the unit will have a manual which will describe what an "MP3 CD" is.
But very quickly, it's simply a CD-R (or CD-RW, if your player supports it)
burned as a Data CD with a bunch of MP3 files, optionally sorted into
folders. Your mp3 "cd player" will likely have limits on how many MP3 files
can be on the CD and how many folders you can have. Also, there may be a
limit to the depth of subfolders you can have, so keep it simple when you
burn your CD-R or CD-RW.

I have mp3 files, and I usually burn my
cd with the Unix burncd tool. I wonder wether I have to do something like
burncd -f /dev/acd0 data file1.mp3 file2.mp3 ... fixate
or use first mkisofs for producing some cd.iso file and then
burncd -f /dev/acd0 data cd.iso fixate

Could someone help me?

I've got zero experience with burning CD-R's in Linux. Maybe you should use
a CD-RW to play with so you can your Linux commands right without throwing
away a bunch of coasters.
