i know how to get it to work, first you need the rlz decompresser then completely decompress the system_plugin_bg, make sure its split into three parts, then take the tga wave studio, and replace your files with the ones in the data folder, then when you goto create a wave, it will compile it to be 3.51 because the split files that vulpix (tga studio creator) were from a 2.50 system_plugin_bg.

and for the opening_plugin, its about the same, if you understood what i just said, then you should know how to get the opening_plugin to work.
