Thanks for the info. Sounds like a better alternative, but how do I transfer my custom rules.ini/spawn.xdp to a map though?
Another thing I noticed. There's no expand2.mix or expand3.mix that was used for adding the unit shps. I opened spawn1.mix and saw that the units are there. I extracted cc_mtnk.shp. For me and another player in cncnet to use a modified shp, we just have to have the same extracted custom shp in our directory?
Update: I found conquer.mix inside main.mix, I found the shps that match the names of those inside rules.ini. So those are the ones I need to modify (e.g., 1tnk.shp)? I can leave the shp in the directory and the other player in cncnet, then we can both play it in cncnet?
