Summary 08900: oric1, telstrat, orica, prav8d, prav8dd: Floppy disks cause crash at start
Description Most floppy disks (over 90% of my collection) will cause MAME to dump at start.

Works with other emulator.
Steps To Reproduce An example disk

>mame oric1 -ext microdisc -flop e:\data\tangerine\dsk\aiglon.dsk

I'm not sure if the prav8d/prav8dd are compatible, but they still crash the same as the rest of them.

Tried some floppies on the "oricutron" emulator, and everything seems ok with it so far.

It's been over a month and nobody could be bothered, so I'm confirming it.

000cf3b50e9e4639dbc40276eba515fe3d152516 fixes the crash and allows at least AIGLON.dsk to load.

I'm not sure this fix is quite correct for Oric, since many users seem to refer to 3.5" discs.

Thanks for looking at that. I'm able to run quite a few disks on the oric1. I have a bunch of disks with 99 tracks and of course they are all being rejected.

Additionally, telstrat crashes when a fdc is attempted to be attached, although I don't know if that was a problem before. I can raise a new report after the next release, unless you want to look at it now.

Since the emulation no longer crashes I'll mark this as fixed - even though there's still related issues.
