[ INSTALLATION STEPS ] 1) Download the song packs you want from the ZiV DDR Legacy Simfile Collection (example, DDR 7th Mix -MAX2-.zip) 2) Extract the files to the "Songs" folder inside your Stepmania directory. Example: C:\Program Files\ITGmania\Songs\DDR 7th Mix -MAX2- 3) Once you have installed all the songs you want, I suggest you clear your cache. Go to your stepmania directory and delete the Cache folder. Example: C:\Program Files\ITGmania\Cache <---delete that folder 4) Start stepmania and let it re-cache all the songs. You should have all the updated "legacy-accurate" stepcharts in your collection. [ Optional Step - Installing RandomMovies ] 1) Download the MAX-EXTREME.zip file. 2) Extract the contents to the RandomMovies folder in Stepmania. Example: C:\Program Files\ITGmania\RandomMovies\MAX-EXTREME Try playing a song (like Breakdown or Cowgirl from DDR Max/Max2) and you should see background videos playing within 20 seconds of the song starting. [ Optional Step - Installing DDR Extreme BG Scripts MOD ] 1) Download the MOD-DDR Extreme BGScripts.zip file. 2) Copy the song file over the existing files within your Songs directory. You can do all at once, or individual songs. This will overwrite the original SM file with a new one which has the BG Scripts for DDR Extreme. 3) After doing this, you will need to clear your cache for the changes to take effect. Go to your stepmania directory and delete the Cache folder. Example: C:\Program Files\ITGmania\Cache <---delete that folder 4) Start stepmania and let it re-cache all the songs. Now you should see the DDR Extreme era BG videos when you play the songs included in the MOD pack.
