Config memory is reset to 0xff and initialized with 'factory defaults' if
a valid header & checksum is not found. Config version number is only
increased when information is _relocated_ or space is _reused_ so that old
versions can read and modify configuration changed by new versions. New
versions should check for the value of '0xff' in each config memory
location used, and reset the setting in question with a factory default if
needed. Memory locations not used by a given version should not be
modified unless the header & checksum test fails.
Rest of config block, only saved to disk:
0xAE fade on pause/unpause/stop setting (bit 0)
0xB0 peak meter clip hold timeout (bit 0-4), peak meter performance (bit 7)
0xB1 peak meter release step size, peak_meter_dbfs (bit 7)
0xB2 peak meter min either in -db or in percent
0xB3 peak meter max either in -db or in percent
0xB4 battery capacity
0xB5 scroll step in pixels
0xB6 scroll start and endpoint delay
0xB7 bidir scroll setting (bidi if 0-200% longer than screen width)
0xB8 (char[20]) WPS file
0xCC (char[20]) Lang file
0xE0 (char[20]) Font file
0xF4 (int) Playlist first index
0xF8 (int) Playlist shuffle seed
