Help me [Some wads dont work for me]

[BarakaJack]

Can someone help me? Some wads dont work for me and I dont know what to do. It says W_CacheLumpNum: 3148564 >= numlumps
For example it says this once I get to the top step of level 24 Only One God on the megawad called 1 monster. How do I fix this?

Use the port the wad was made for. Read the text file to find out what port is best to use.

Thanxs I felt dumb asking

Ive downloaded zdoom but i dont know how to upload wads for it to play. Can you tell me?

The simplest way is to drag the wad file over the zdoom exe file. Beyond that, you could also create a shortcut to the ZDoom executible and write in the command line "-file wadname"
