Well, I have some good news, finally. I managed to recover the file for Volcanion's sprite, but it's the unfinished version, unfortunately.

I really don't have it in me to recreate what I did... I'm usually great the first time around if I do something, but if I have to do the exact same thing again, I suck at it... You could sort of call it "beginner's luck." (Also the reason why I am devastated if I forget to save a game before I turn off, let alone if I lose the save file.) I really hope my sprite could be of some help... If it's possible, anyone that wants to could finish the rest. I pretty much have all the colors that are needed, so that wouldn't be a problem. Sorry that it's in this condition
Now, on another note, I need help from any fellow animator that is in this thread... For a few things I am doing, I have a few custom sprites that play a big role in a ROM hack I'm making, and using the sprites, I'd like to have them animated BW style, for the front page of the site I'm posting this on. (Trust me, I would do this myself if I could, but I don't even have a program for animating, so I would have to make a picture file for each frame and then make it into a gif). The main Pokémon I'd like to have animated are Riolu, Ralts, Eevee, and a Fakémon of mine, Petaw, who I envision to have a similar animation to Pansage. I already have Ralts's sprite done. Petaw's and Riolu's are also done, but I'm thinking of redoing them.
Again, I apologize for the non-transparent background, but it was either that, or a full white background, and that would have caused some issues considering that Ralts is also white. Plus, the background color has to be something completely different than the sprite itself for the game to read the transparency from the sprite. Otherwise the in-game sprite would have a big box around it. If you're interested in any way to help out, please don't hesitate to PM me.
Anyways, that's all I have to contribute for tonight... Sorry for my leave, but I hope to try to get things back in order on my end. I might start working on
Hoopla Hoopa next, if I can.
