the original protected version? I was only aware of a "Tekken 3 Special" which had no protection
similarly all previous dumps that I've seen around for Wu Kong Wai Zhuan and for Feng Kuang Tao Hua Yuan / Insane Paradise came from unprotected carts or had protection hacked out, which maybe have the advantage of being playable in every emulator out there, but do a very poor job at documenting the original versions who were produced with copy protection wirings
hence, for me cah4e3's dumps are really welcome
