Right now, on sd2iec (the firmware that uIEC uses), I implemented file 
positioning by taking advantage of the fseek functionality of the 
underlying FatFs library.  To get to record 5 (with each record 50 bytes 
long), I just fseek to 5*50 and read 50 bytes.  As an added bonus, the 
'P' function works for non-REL files as well (it just positions to the 
actual byte in the file)

Yep, though I still need to implement REL files in D64 images, which 
will require using the side sectors... :-(
