Seriously, as I said, I have an Amiga sitting right here, and I can easily make DMS images (barring any read errors on the disks). Just get the disks to me, and if they are indeed standard Amiga disks without protection (I am 100% sure that if they are indeed Amiga disks, then they are unprotected), then I'll DMS the disk, and distribute the images completely unmodified. I'll also dig up some Amiga disk tools (DiskSalv was my favorite back in the day) and investigate to see if there are any deleted files that can be recovered (the chance is high - on a semi-unrelated note, it's a well known fact that early Kickstart disks have some deleted development files on them).
Get me the disks. Unless they're not Amiga, I will make DMS images of the disks available. I've never used Disk2FDI, but that's quite overkill if these are standard disks (and I can't imagine them using DPaint with non-standard disks). I know other systems did have a port of DPaint (including, IIRC, the PC, Apple IIgs, and Atari ST), but the Amiga was most known for being the best machine to run DPaint on. And, if they did use DPaint, then the files should be standard format - either IFF ILBM images, standard DPaint brushes, or ANIM5. It'd be especially interesting if they used DPaint's animbrush feature to test how a sprite would look while animated - it's a breeze to create a simple mockup in DPaint using the automatic Move function with an animbrush.
