I'm sad that I never came up with a way to convert my animation files from Amiga to a PC-friendly format. I did record them to VHS via a genlock, and recently digitized the VHS tape to a PC file. But there were glitches on the 20 year old VHS tape, of course.

If you can still read the original files, try
Multishow. It uses Java, so it's platform independent, and I just used it to recover a lot of old files ... including that wonderful image of Legion's Phoenix that I'd downloaded and saved a decade-and-a-half ago. It will even display IFF Anims and supports register cycling. Maurice's method of saving animations frame-by-frame is superior, but possibly tedious, especially if you lack access to the original software. So I used Multishow and a screen recorder at several different FPS settings and have pretty good captures of the animations, and could break them down to individual frames from that for later reconstruction.
Here's a hand-drawn picture of the motion picture Enterprise that I made using DeluxePaint in high-res, interlaced mode back in 1986-87. It's the first time I've seen her in in nearly 20 years!
