Help with folders/names for "random" textures (in SD card)

[Rajam]

Hi; While searching for textures, I've found some nice effects and stuff (like Red Thunder for Pikachu, Dedede's helpers with textures, etc etc) but I have no idea in which folders, and with which name should those textures go in my SD card... I have already searched some guides here but nothing on these 'random' textures... I need help with this; thanks in advance
