Summary	06953: x68000: Doesn't recognize changed disk when the changed disk directly (without eject first)
Description	http://mametesters.org/view.php?id=6942 related to this bug. MAME now recognized 'new' disk so it can make new data disk in Sangokushi III. but after that, when I change disk to game disk C, MAME doesn't recognize changed disk. Edit: It works when I changed 'empty' disk and then insert the disk. but when I try change the disk directly, it doesn't work. I think this is related the 'feature' of X68000 that auto-eject the FDD when it needs change disk.
Steps To Reproduce	1) Play Sangokushi 3 (Data disk A in A:, data disk B in B:) 2) Change B: drive disk to game disk C when message appears 3) When main menu appears, make new data disk to new xdf disk 4) New data disk make works 5) But after change game disk C when message appears, MAME doesn't recognize changed disk (wrong disk message appears)
