D81 write to disc

Sorry If it's lame but I still can not figure this out after trying many ideas.
How can I write a .d81 disk image to 3,5'' disc (1581)? Is there a tool for this?
I have U1541 and .d81 image on a SD card. How to...?

Yes. I'm talking about Ultimate 1541-II. what else? ;)
It can emulate IEC drive (f.e. device #10) so I thought this feature could be exploited somehow. I'm pretty aware ultimate can't mount d81. figured it myself ;)

I think I saw some thread here where somebody mentioned some tool to write d81 images from SD2iec device to regular 1581 drive. Or was I dreaming?

any help actually is appreciated.
and no - old PC's are not the option here.

Here's another Windows-based option that utilizes PC's own floppy drive by installing custom driver for it, used this myself for years with success.

It's possible to use my d81 writer plugin if the 1541U-II is up(down)dated to emulate an IDEDOS cartridge.

Not straight forward, but doable.

...and again this is not exactly what you asked for, but at least it is a different kind of option:

Warpcopy06 D81 [bugfixed]


MMC64 D81 writer

Maybe one of those caused the dream you had?

Zipped or gzipped d81 images can be written with:

all programs look promising and probable they are what I'm looking for but:
Iec drive emulation under ultimate 1541 probably causes issues (thats my guess).
I have the .d81 image on device #10 which is software iec device emulated by ultimate 1541.
when I run gunzip ant it asks for input file form device #10 and #8 as target 1581 device I get an error on reading this file (31.Syntax error)

I think I'm close to the solution but probably the gunzip tool can't talk to software iec drive or ultimate emulates the tool badly.

anyone here copying d81 images to the physical discs using ultimate-1541 card?

Currently Ultimate IEC doesnt support all commands that are needed for using theese Tools.

afaik theese tools use byte read, which is currently not working and due that you get the syntax error from ultimate iec.

I needed to test myself as i wasn`t in the need of this before.

Since you have a standard d81 and dont own a mmc all the tools listed before are not suiting your needs at all.

So i checked some other Tools available.

CBM-Command Version 2.3

will successfully write a d81 from sd2iec within 17 Minutes on a Jiffydos equipped 1581.

but still no Ultimate IEC support.

yeah. I've found this CBM Command tool mentioned in some forum thread and tested it yesterday. but no luck. Same problem - Cant read dir of IEC #10 device.
I was able to read the main dir of IEC #10 device once or twice but it didn't displayed (found) the .d81 images on the main root catalog. only subdirs.
