Just out of curiosity, is there any good reason not to convert the steam version to the old game with the 7th Heaven converter? I just recently bought the steam version and converted it, and have been using Reunion's field models, battle models, translation, and menu mod while also adding the Waifu background upscales and Anxious Heart. I haven't had enough time to really play much of it yet, but since I just saved the video files from my Steam Version before the conversion to the old PC version I don't really see any benefit to keeping it as the Steam version.
I have been wanting to get the game to basically an "HD remaster" status so I could hook my laptop up to a tv, connect a console controller, and have my fiance play it so she might see why it is my personal favorite of the series.
