How to make disks for a IIGS?

I think I just figured it out! I just made a GS/OS boot disk!! So, I put the files onto a flash drive and then put the flash drive onto my Rev. B iMac G3 (which runs Mac OS 9.2) then put those files onto a floppy disk (via a USB floppy drive) then transfer it to a older machine, one with a floppy drive and that can format to Prodos disk (I used a Power Mac 4400/200). Then, on the older computer, you get another 1.44 floppy (preferably one you don't need) and put tape over the hole on the right side of the disk and insert it, it'll ask you if you'll wanna format it to ProDOS version. Then take the first floppy and copy the files from the first floppy and put it onto the second. That should be it!
Been struggling a lot to make a boot disk because everything I find is in .2mg format, which Disk Copy 6.3 and DiskDup+ can't do anything with. I even tried Disk Copy 4.2 and that didn't work either.
I know Apple had ProDOS disk images for GS/OS hosted on their site, is there a backup of those images?
EDIT: I tried using a program called CiderPress to convert a .2mg to a .dsk but the .dsk file isn't being recognized by Disk Copy 4.2 either.

I have a variety of Macs that can write images back to floppy. I mainly use a Beige G3 desktop for that because it has a decent sized HD and USB. I wrote my IIGS disks using that.
Curious though, my Apple IIGS floppy drive says 1.4MB near the eject. It is an Apple drive but it only reads 800k. Didn't Apple sell an interface board that you had to plug the 1.4MB drives into because the built in one can never work with a full 1.4? IIRC that is the expensive part. I could be wrong because I was never really into Apple that much until later on.

What is the model number of the drive? Apple sold an external Superdrive in the same case as the 800k drive, the model numbers are G7287 (1.44mb) and A9M0106 (800k) respectively. The Superdrive version will work with a IIgs but, yes, to use it at its full capacity you need a rare interface board. Otherwise it's functionally identical to the 800k drive.
Reactive Micro sold a clone of that interface board and, yes, it cost a fair chunk of cash.
I have a picture of it on my MacBook here so I have attached it so you can see the front of the drive. I don't have a picture of the model number, though. I will check it when I get home.

Hmm. Mine is the A9M0106. Weird it is 800k model but the label on the drive says 1.4MB. I haven't opened it in a while. Do these drives also work with Macs that have an external floppy drive connector?

Yes.
As olePigeon noted it's possible someone changed the internal mechanism and labeled it appropriately. Inside those drives is a normal MacII-era mechanism cabled to an adapter board that provides the daisy chain function, a SuperDrive cables right up.
Cool. Thanks for the info. This is the first Apple II I have ever owned. I used them in high school but that was the extent.
It's for apple ii emulators. It's basically like a .img (or .vdi on how you look at it) for apple ii, kinda
