fixed bug where floppy data buffer from previous session would be saved to next session's floppy buffer when cartridge loaded. added xml parsing option for remapping dos added FDC_RESET_STANDBY debugging output, however standby and clock functionality are not implemented yet. added debugging output detecting whether a floppy disk image already exists for a current rom, and creates a new disk only if one doesn't exist.
