1) the firmware is the new R4 firmware coming out, that has built in action replay cheat device.
2) you dont name it CHT, that gets done by the editor, when you use it, oh lol that reminds me, people on gamefaqs were wondering what CHT meant, as there were many users they have faced with it. It took a while for someone to say what it meant.
Hope that cleared some things up for you.
well if it a firmware for R4 thn i am so waiting for it ^^
BTW where do u get tht info tht R4 will have action replay support??
