Yes, yes, I meant Dark Half. And it's already kicking my ass. It's full of fancy graphic tricks that I now have to learn to capture. But it's going OK so far.
As for Ys 5 I used BGMapper. Go here:
http://pikensoft.com/And download and read about the BGMapper tool you find there. BGMapper is great for sucking hidden or distorted graphics out of lots of SNES games. If a game looks like it's using a graphic trick BGMapper can usually show what's really going on.
Energy Breaker mapping is what I'd call bizarre difficulty. The over all mapping is easy but applying all the graphic layers and arranging the rooms gets really complicated real fast. You'll find yourself reworking the same spot over and over. I'd love to go back to it but it's just to huge a project.
