* Fix cart info if ejected not in drive menu * Fix a couple ramdrive issues - Unmount ramdrive if Slot-2 RAM is ejected - Fix potentially reading from the wrong location if numSectors > 1 and crosses between locations - free ramdLoc on regular DS too - Use calloc to 0 initialize, I saw it mess up occasionally on DSi too * Update time in the Vblank handler
