I did some digging around and compiled a working GPSP. Yes this works on 1.67 without any saving issues. You can even transfer your old saves. I loaded up my Pokemon save and it works great.
Be sure to read the README if you don't know how to prepare homebrew for use with vHBL. i worked quite a bit on putting this together, I'd appreciate a thank you here and there I take no credit for the actual content!
