How to play custom maps?

Hi, I'm fairly new to the whole source port thing, and I have no idea whatsoever how to get custom maps to work with Doom Legacy. I'm trying to play some of the dwango maps multiplayer and can't figure out how to get it working in Legacy. Can someone help me out here? Thanks.

Well, I don't use Legacy, but I can tell you this much. Put the .exe file and the pwad in the DOOM or DOOM2 directory. Then, click start, then run, then type in something like this:

C:\DOOM2\zdoom.exe av.wad av.deh

That's what I do when I want to play Alien Vendetta.

Hope that helps. =/

I think for Legacy you'll have to do legacy.exe -file something.wad -deh something.deh. Or you could just use the launcher.

Yeah, I figured out how to do it using the launcher - thanks though. I've started using jDoom anyway, it's so much nicer with the hires textures and the 3d models. Now I need to get it onto my schools computers for some old school deathmatch fun - and we don't have any cd-rom drives. Floppies it is then...
