Does MAME support raw floppy disk images?

I'm trying to get 231 to boot CP/M for a Kaypro 4/83, but no luck. It attempts to boot with a TD0 or IMD image, but never does get to a prompt. So that is the first issue. If I could get it to boot, then can it also support using just a raw disk image like .dsk, .img, etc.?

It's always a good idea to look into the software list, to see what's already known to work. So, the 4/83 is known to MAME as 'kayproiv'. The software list has one entry, a CP/M boot disk.
software name="kiv22" CP/M 2.2 for Kaypro IV sharedfeat name="compatibility" value="D" part name="flop1" interface="floppy_5_25" dataarea name="flop" size="0x056639" rom name="kiv-22.imd" size="0x056639" crc="99182539" sha1="d4b5a6a0a0038fc12aa39a7dd17006f1c71198df"
So, find that disk and you'll be good.

This is good advice - I did this and it does work. What I was trying to do is find good/working software for a real Kaypro 4/83 and hoping MAME could help me do that. One issue is trying to get images in the right format and without errors. In this case, MAME rejects the TD0 file I downloaded, but I finally found a tool called samdisk that when converting it to an IMD, it will work under MAME.
I am really surprised though not to see a raw file format, that would have been helpful yesterday.

Not sure what you mean by raw. If you mean a sector dump with no headers or gap bytes, yes we do support that. The extension used is "kay", although dsk can work too.

I've tried both dsk and kay, and they won't boot. Maybe the raw image needs to be in the interleaved disk order and not flat?
Thanks!
