Change Enemies In Cyberworld
First of all, get a MegaMan Battle Network 4 Red Sun or Blue Moon. You will need two GBA/SP, and a GBA link cable. Go to Ciel's room in the place you go to after killing Omega. Press up in front of the computer. Go to Transmission. In Red Sun/Blue Moon, go to Comm. Go to trade chips, and trade any chip into Zero 3. In Red Sun/Blue Moon, you will get a secret chip. In Zero 3, all Cyberworld enemies will be changed.
