Patching extra functionality into <gamemd.exe>

[Marshall]

There is a PKT file in one of the mixes (I think it's langmd.mix, though I can't imagine why it should be language dependant).
RA2/YR can read a second PKT file that is loose in the RA2 folder.

If you have multiple loose PKT files however, your map list gets duplicate maps (I have only noticed having 2 of every map in the list).
This happens even if all 3 PKT files are completely different.

For this reason, the Assault maps do not include their own PKT file.
I'm not sure how useful it would be to be able to have multiple PKT files but I think I've heard people mention advantages.

Regarding your recent super weapon work, very impressive. However, I still think that it would really complete things to be able to have a non-IE-inducing sell unit superweapon (simply preventing it from selling tank bunkered units would be preferrable - though I'm not sure how simple that would be for you to implement).
