Tinkering with items like the Teachy TV and such has been somewhat limited. Routines to edit the items use are feasible. But mainly for those with an understanding of ASM. Personally, I think though you could get around this by using some shortcuts if the item works like I think it does. Being a hacker with only a small skill in ASM I do not know how to locate the offsets to each routine and such but I think if you could work around the way these items work you could use them for your advantage.
