Years ago I started working on an English guide for Sparkling Feather, as a part of my PC-FX English guide series. Unfortunately, I ultimately abandoned that series of videos. However, I kept all the resources on hand and opted to repurpose them for a blog post on the PC-FX Fan Club. While it may not be a complete guide, I hope it helps you get the most of our Sparkling Feather.
Check it out on the PC-FX Fan Club.
