I could add a sort of glow but the problem is, I'm not a very good artist so I wouldn't be able to make it look good. I usually rely on other people for graphics and I do the work that gets the graphics to display properly.
Well the tablet idea is for Genesis and I don't think that it would really work in another game because it displays a legend that pertains to Genesis' plot. However, the other stuff is just a lot of mini-features that could be ported to other ROMs so I don't see why not. Though I'd probably have to get Thrace's permission first. Even though I was the one that did the work, most of those projects were his ideas and I'm not sure if he would appreciate other people using them.
