Sharp X68000: How to boot from floppy after a reset?

[HazukiXX]

So, I'm playing Akumajou Dracula and I'd like to be able to soft or hard reset it in the middle of the gameplay. The only way I managed to do so is by entering "UI Controls" mode and pressing F3 or Left Shift+F3. However, doing so sends you to this screen:

Translation:
"Akumajou Dracula UserDisk Creation / HD Install version 1.00 Copyright 1993 KONAMI"

"This software is only effective when booting from a floppy disk to prevent operational errors.
Reset the computer and boot from "floppy disk 0."

So, I'm guessing mame is booting the system from Hard Disk by default. How can I make it so it will boot from Floppy?

Can't find a manual handy, I speculate a game reset can happen with a button combination if not by physically pressing the NMI reset? (which is unhandled by driver on a quick glance)

The game automatically ejects disk one after it starts so you have to reinsert it when you reset.

And what would be the commandline argument for that?

[sairuk]

doubt there is one, you probably want to look into leveraging the lua subsystem to detect the reset and reinsert the disk you are after.

I suppose there's also no way to add an extra command at the initial boot to make it so the system wouldn't automatically eject disk 1 after the game starts?

Alternatively, it seems like the game also has a native soft-reset function. You simply have to press start+select. However, I don't know what are the default mame keys for those.

Pressing only "start" in a real X68000 pauses the game, and pressing Keyboard Number 2 or 3 in mame also does that, so I'm guessing those are the equivalent keys for it in the emulator? (not sure why there are two instead of only one). But I have no idea what the equivalent key for "select" is. Which one is it?

Systems with powered eject floppy drives tend to get very grumpy if disks don’t eject when they should.

Well, I guess I'll close this then since there's no apparent solution.
