McWill, I just want to throw this out there... okay.
Forgive me guys as I know it's an Atari forum, but..
McWill, do you have access to Sega Game Gear?
That one is in the same desperate need of this mod.
I can't imagine you wouldn't find sales on some forum if you crack that one.
If your taking orders I will see if I can pitch in for some.
I already made tests with the Sega Game Gear, but it's long time ago!
The solution is very close! I inform you, if any news.
