When posting sprite packs please label what game they are from, the company, credits, and if there is any color separation. Me or someone from staff will add them to this post.
If you wish to share or require some single animations/sprites to particular characters you should look in the Spritesheet Expansion Thread (http://mugenguild.com/forum/topics/spritesheet-expansion-thread-146532.0.html).
For many custom states such as electrocution or midnight bliss animation you should look in the Midnight Bliss and Shock Project (http://mugenguild.com/forum/topics/midnight-bliss-and-shock-project--79126.0.html)
