* Bring over updated fat lib from DE kernel. * Updated Write_SD_sectors function to include fail condition check introduced in DE's kernel. * Removed old/unused copies of fat lib. * Refactored button detection routine for skipping autoboot/triggering boot last SD list game. * Press A to boot last played game from PSRAM actually triggers now. Unfortunately it doesn't actually seem to be working right now. Previously due to how the old button detection code was setup, the press A code wasn't triggering at all. * Press B option provided in commented out code for dumping fat table. Compile with this enabled (and the related changes in EZcard_OP.c) to enable dumping fat table to SD prior to booting game. Useful for debugging fat table related stuff for custom kernels/external launchers on DS. Disabled by default as this has no practicle use for end users.
