Need Help w/ Game Setup - Files and Directories

[lifemax]

I have TTDX Windows files on my Hard drive. What is the correct setup - the relationship of TTDX files, the patch, openttd, etc. Do I just put it all in one big directory? Or do I load OpenTTD over the original TTDX files and choose overwrite on the duplicates? What's the differenec between "patch" and "openttd"? Thanks!

What is the correct setup

For TTDPatch, you extract it into your TTD directory, and you extract ttdpbase.grf or ttdpbasew.grf into a subdirectory thereof called "newgrf".

What's the differenec between "patch" and "openttd"?

About the same as the difference between Linux and Windows.
But usually we call them either "TTDPatch"/"OpenTTD" or "Patch"/"Open". Note capitalization. "patch" and "Patch" are not the same thing.
