==Changelog==
==Changelog==
'''2005-06-12'''
'''2006-03-03'''
* Successfully reverse engineered the reading of compact flash cards
* Improved NMMC (MK2 / MK3) driver
* Optimised LFNs into loops, thanks to dwedit
* Optimised SuperCard SD CFC7, thanks to Cory1492
* Added file attribute support
* Added read only M3 SD support, thanks to SaTa and Moonlight. Disabled by default due to incompleteness
* Fixed SuperCard SD reading, thanks to Loopy
* Added EFA2 support, thanks to CyteX


'''2005-06-13'''
'''2006-02-09'''
* Started work on file system driver
* Fixed file and directory names starting with a dot ("."), or containing more than one dot
* Added Neoflash MK2 / MK3 support, thanks to www.neoflash.com
* Modified CF access routines to mask of the high byte of the status register, hopefully improving compatibility
* Added disc caching, thanks to www.neoflash.com . It can only be enabled on the DS (not GBA) since it will consume 128KB of memory on the default setting. It is advisable to call FAT_FreeFiles() before shut down if caching is enabled, to flush any writes to disc
* Added Supercard SD test code. It unfortunately doesn't work, and is disabled by default
* Added FAT total size and type functions
* Added file creation and modification functions. Disabled by default, see gba_nds_fat.h for more info
* Fixed AddDirEntry bugs:
* should no longer corrupt a directory when adding a new file
* no longer puts garbage into a short file name's extension, thanks to 0xtob
* long file names with less than 12 characters now work, thanks to DragonMinded for pointing it out
