I'd love to do that at some point, but I'm not sure if I'd be able to do it this side of the next 5 years. Just because I'm still very much an amateur in game development, but specifically programming. If I can't even get a normal turn-based, separate-screen battle system to run without much frustration, I'm pretty sure I won't be able to do an on-map system very well, at least, not without help.
@alpha123 - In your screenshot the font is super blurry; if that's one of my old conversion let me know so I can replace it in my common files package.
