I found the game only a few days ago, and of course I'm blown away by how awesome and how much fun it is.
Welcome in MM8BDM, and the Forum.
1. Some servers say "make sure you are using the exact same wads" and wont let me join. But I downloaded the newest release and have no idea what the hell i need to do.
These Servers use as you guessed Special Wads for Special Maps/Gamemodes. In this moment, i guess you will just need the roboenza.wad and the Ivory Pack, there arent many servers using special Wads i guess, only Deathwinds LMS and DM Server. You can get the Roboenza File from the
Homepage of Cutstuff. The Ivory Pack is at the Top of the Homepage as well.
2. How can I play as Helmetless Mega Man or Break Man?
Those Skins you see are Custom Skins. They have to be added into the Game and can be found
here.There are also many Skins, but most Skins cant be seen if you dont add them into the Game, so much Players wil be seen as Megaman.
If you search another Skin, try out
This Topic, there are much Skins, more than you need i guess.
Tipp: If you put the Skins in a "skin" folder in your MM8BDM Folder, you mustnt ever add the skins single. Or (Like the others said) you can unlock them in the Console Ingame. type in "Skin Protoman-Break" or "Skin Megaman-Hair". But you can unlock 3 Other Skins. type in Skin Wilyskullsuit, Alien and Auto.
