Own music can be implemented quite easily, customizing Simutrans to your liking. You only have to place MIDI files in the subfolder music, which is under the main Simutrans folder. After that, you also have to edit the file music.tab which is placed in the main Simutrans folder.
Although there are many translations existing, you might also wish to make your own, to customize Simutrans to your native tongue. This can be done by editing the texts in the subfolder texts. The .tab files in this folder are the initial point for translations. When started, Simutrans reads all the .tab files it finds. The names are usually two letters, which denote the language code, i.e. en.tab for english language. The texts are dually. The first line is the original text, and the line below the translation, that should be applied. There should also be a translated subfolder with the same name, as the file, i.e. for en.tab it is the subfolder with the name en. It contains the help texts in the HTML format (Hypertext markup language). It is the same format used on the internet for web pages.
