It works anyway even reborn but I will make a note about. "Skill Points Don't Descrease" only works if you have at least one skill point, if you don't have it doesn't works. And the same conditional for "Skill Points Increase When Used" I guess.
Other note is "Infinite Status Points" pressing...
If you are using the new EOS don't need convert to .scc, just download usrcheat.dat from gbatemp's database and put into _dsone folder. If you are using the old OS try with this link
