ok so i was already looking at a PSA guide here http://www.smashboards.com/showthread.php?p=7684133

but which actual program do i use? do i have to use ASH? or is there a more specific one? what you described seems pretty simple, im just not sure which program to use since there are several listed in this guide.

ok, so i downloaded a custom texture and moveset, but the character is way too powerful. 

What program can i use to adjust the power of his moves, while leaving the character moveset unchanged?

(Basically, i just want to perform a damage nerf)

i tried searching briefly but couldnt find much, if its pretty obvious i apologize.

thank you in advance!
