Translation of this text by ghost_jp:
Some time ago, a guy (illegally) making a copy gave us a phone call. However, who says which software maker feels delight against a guy making a copy, stupid! At seeing such a guy, I have an urge to punch to him. To somebody who read this (he means this message on the ROM), never do making a copy. I can't understand what is on the mind of such guys making a copy. By PAC FIREE.G.K.1
I filled in gaps some words in () for your understanding.
