So, I finally got heart gold too work; it works on the DSTT unofficial firmware 1.18. however, Black and White don't work on it, getting an errcode -5. I've tried replacing the ext info and sav lib files, but that doesn't work. It seems that the TTmenu.dat file is the problem. Is there any way to get Black/White working on DSTT unofficial firmware 1.18? Is there firmware later than this?
