Here's how to install custom content in Real World Fly Fishing:
When you’re ready to start exploring the custom content for the game, this guide should help you get started. First it will help to understand how content files are organized in the game:
The folder where the game is installed contains several other folders including “outings”, “fish”, “food” and “sounds”. The outing folder contains one folder for every outing in the game. The fish folder contains one folder for each species of fish, and the food folder contains a folder for each type of prey that you could see when you check the hatch. The sounds folder doesn’t contain any other folders, but just contains sound files.
For example, the main folder contains a folder called “fish” which contains a folder called “RainbowTrout” which contains a number of files. New fish species need to be added as new folders in the “fish” folder, just as new outings need to be added as new folders in the “outings” folder. If files or folders aren’t arranged in this hierarchy, the game won’t find them.
When you download a custom outing it will usually be in a zip file. Open the zip file and see what it contains. If it contains a folder called “outings” (and possibly the “fish”, “food” and/or “sounds” folders) then the zip file contains everything you need to install the outing. Just “select all” in the zip file, then drag and drop the files into the main folder of the game on your hard drive. Windows will warn you that the folder already contains a folder called “outings” and ask if you want to continue. Continue and the files will be installed. You might be asked about merging other files in the process, but just agree each time. When it’s done installing the files, you can start the game and you’ll find the new outing ready to fish.
Some outing zip files contain only the new outing folder and not the fish, food or sound files the outing needs. This requires a bit more work to get the outings installed, but outing developers sometimes distribute their work this way to keep the new outing files smaller. You might just find a single folder in the zip file named after the new outing. For example, if you just see a folder called HuckleberryRiver, you’ll want to drag that folder and drop it into the outings folder on your hard drive. How most people handle these outings (that don’t come packaged with fish, food or sound files they need) is to simply download and install all available fish, food and sound files from the clubhouse. There are over 200 species of fish, but they’re available packaged into just a handful of zip files. You can download those files and move the folders from them into the fish folder. You can do the same for food and sound files. Once these are installed you can download any outings you want without having to track down other files they might require.
When you start the game, if there’s any custom content installed the game will scan your installation to make sure all the files needed for those outings are in place. If not, you’ll see a listing of any missing files. If that happens, make sure you’ve downloaded the fish, food and sound files, and that they’re arranged correctly (each fish species in a folder within “fish” and so on.)
