Dropping more sprites, hit animations that im using for my custom x-pirates modification, but the vanilla set directly modify the standard hit#26-46 for bullet/laser/plasma (ive modified lasers to be blue so they have a blue hit sparks, just more sparks than the standard bullet hit). In the x-piratez mod started with index 256 for the upgraded hits to bump up reasonably past the ones diox has defined
