To use

1. Unpack and rename {Trails in the Sky 1st Chapter}/pac/steam/asset_common_model.pac.  Place the unpacked "asset" folder in the root {Trails in the Sky 1st Chapter}/ folder (same folder with sora_1st.exe in it).  The default location for Steam is {Steam}/steamapps/common/Trails in the Sky 1st Chapter.

2. Copy the contents the assets folder into your root {Trails in the Sky 1st Chapter}/ folder.

I own none of these assets, I just did the work in porting them.  This mod is free, and originally posted on loverslab.com.  -amorrow28
