2005-11-06 - Chishm
* Added WAIT_CR modifications for NDS
2006-02-03 www.neoflash.com
* Added SUPPORT_* defines, comment out any of the SUPPORT_* defines in disc_io.h to remove support
for the given interface and stop code being linked to the binary
* Added support for MK2 MMC interface
* Added disc_Cache* functions
2006-02-05 - Chishm
* Added Supercard SD support
2006-02-26 - Cytex
* Added EFA2 support
2006-05-18 - Chishm
* Rewritten for FATlib disc.c
2006-06-19 - Chishm
* Changed read and write interface to accept a u32 instead of a u8 for the number of sectors
2006-07-11 - Chishm
* Removed disc_Cache* functions, since there is now a proper unified cache
* Removed SUPPORT_* defines
* Rewrote device detection functions
* First libfat release
2006-07-25 - Chishm
* Changed IO_INTERFACEs to const
2006-08-02 - Chishm
* Added NinjaDS
2006-12-25 - Chishm
* Added DLDI
* Removed experimental interfaces
2007-05-01 - Chishm
* Removed FCSR
