Hi! That could definitely be done, though it's not something I'll be taking on myself :p
The reason I picked Gameboy as my target platform was 1) the ease of use of Gameboy Studio, and 2) it's the console I have the most nostalgia for :). At it's core, Higurashi is mostly text, and you could probably make a Commodore PET port if you put in the time.
I'm happy you responded and it opens up the possibility of this happening. I replayed this port a lot, and it felt very natural. I was just thinking about Higurashi and it reminded me of you.
If the port to, I don't know, Mega Drive ever happens, there's a tool called SGDK by Stephane-D, where ports have been and are being created without thinking about it. I hope this will eventually become something. Big hug, and sorry for the question.
