For those who don't know, in the .rar archive there is a file called itemtype.dat
You have to put this file in your Conquer 2.0\ini folder (If you used standard installation, it's C:\Program Files\Conquer 2.0\ini\ )
So what you want to do, is replace the original itemtype.dat with the 'better/edited' itemtype.dat
Also: If you don't know how to open/extract a .rar file... go to

, download WinRAR and install it, then when you right-click on a .rar/.zip file, you can click some Extract here... buttons or whatever you like.
Hope this helps
[edit]This itemtype.dat file doesn't support the bronze/silver/gold prizes or cups, so if you use this itemtype, you won't be able to see those items. [/edit]
