I was recently inspired to capture some sprites from Capcom's Gem Fighter/Pocket Fighter game. There are some fantastic animations in this game.
Most of the animations are pretty basic, 2-3 frames each, but Felicia's MegaMan transformation was a bit more involved. Here's what I came up with.
Feel free to grab these, but please give credit if you use them, and definitely do not link directly to them. Thanks!
