This Tut is mostly for nameless but hopefully it helps others too.
What we are going to be learning is how to easily turn a set of screen captures from a 3D fighter like SSB and tuning it into a sprite. :-*
What you need: Photoshop (or paint if your poor and willing to work a bit harder.) and a free demo version of Game Maker (this comes with almost all features of the program and has to time limit :D). To get Game Maker follow this linkhttp://www.yoyogames.com/gamemaker/try
Step one, get a screen capture from a side angle (easy in SSB, little bit harder in other games) with the image you want to make into a sprite and SAVE it.
Step two, open the image in photoshop/paint and remove the background (this can be done in paint with the free form select tool)
Step three, open the image in Game Maker's sprite editer and say Image>>Outlune(remove image)
Step four, using the screen shot as a reference, fill in the outline. (im to lazy to finish filling it in but this should get the poit acrosss)
hope this helps :-X
