Here is how to add your own sounds to StarTopia. The sound format is a Mucky Foot creation called TFA. To convert your WAV files to TFA format, for inclusion in your own missions or to replace the wonderful samples, you need the following:

• A 1.0.1 patched version of StarTopia
  
• The WAV files you want to use, converted so they are all 22Hz 16bit mono

First back up any sounds that you are replacing. Then to convert the WAV files place them in the folder they will be called from (e.g. StarTopia\data\Speech\English\lev01) and call them the appropriate name objective01.wav for example for a WAV that you want to replace objective01.TFA with (in this example it would be wise to rename the original to objective01backup.TFA or similar). Then copy the shortcut that you use to start StarTopia with and add

/tfa

to the end of the command line. Run that shortcut and play the mission you want the sample in and play through the mission to the point where the sample gets called. There will be a slight pause while it is converted to a TFA on the fly but then it will get played. The only other point is to remember to remove the WAV from the folder once you are done.

There you go, you have added a sample to the game. Now you can include samples in your own missions but remember that sounds can end up bloating the size of your mission zips.
