These instructions should be easy enough. If you have trouble downloading winrar, just click the 32 bit English version. Download and run. Notice there are 3 parts to the game. Just double click any of them and extract. They will all extract together. After that, place the Audio folder inside the folder that you extracted. Make sure to place the folder where it it has a file with an extention .rgssd or something like that. It should run fine.
Also if you want the fonts to work, either copy paste them into your fonts folder in your system folder, or run the game as an admin if you use Vista.
