Please have 3x more frames. 8 are not enough for this fidelity:

I know NEO-GEO has used alot more frames than most consoles, games or even arcade's but most explosive effects were done with 4-8 frames. This is meant as a higher quality but not a smooth pack like that. I'm certainly looking into making smoother packs for that effect, and appreciate the reference you provided.
