Summary 09264: sbrain, sagafox, sagafoxf80: Regression - will no longer boot a floppy
Description All 3 of these systems used to boot the floppy disk that's in their respective software list.

Now, they just do nothing.
Steps To Reproduce >mame sbrain boot

You should get a screen asking for the disk, hit enter, it boots. But it doesn't ask or do anything now.

>mame sagafox foxcpm
or
>mame sagafoxf80 foxcpm

It will ask to press F or W (F should work), but pressing any key does nothing.
Additional Information It was working in 0.254 - don't know when it broke.

I went back to 0.219 and sbrain always shows like your sbrain.png snap.
0.218 is: Error: unknown option: boot

The breakage happened some time after 0.254, so you need to look between 0.255 and 0.280 .

uh, I'm saying 0.219 looks exactly like your snapshot after 0.254 for me (so no insert disk)

The problem is that now there's just a block cursor at start, and nothing further happens. It used to boot a disk, now it doesn't. That is the reason for this report.

For sbrain:

I should clarify that the first screenshot appears if you start the system without a disk.

Once it shows, use the File Manager to load the disk.

But, in the current state of the driver, that message never shows, it just hangs with a block cursor.
