Hmm... couldn't get the config.ini file to change. I'd edit it, save, then boot openrct2, and there'd be no change. Check the config file, and it would have reverted to the original path.
Moved files over to the GOG install, and that seemed to work, but, of course, lost me access to them in the rct2 install, and openrct2. Then uninstalled my original rct2. Opened openrct2, it couldn't find the rct2 exe, and it asked me to direct it to the path. I directed it to the GOG install, and now everything seems to be working just fine.
So, seem to have gotten everything working now. Thanks for the help!
