I already have a portable Duo. I call it MagicEngine and I run it on my
laptop. I have a usb gamepad hooked up to it and I can enjoy my Duo games
wherever I go and there is no need to destroy a perfectly functional Duo.
Sure, some people may say that MagicEngine doesn't give you that authentic
feel but isn't that the whole point of so called emulators? Aren't they
here to preserve the game systems? I only have one Duo and with
MagicEngine, I also have an Express/Duo hybrid. I'm not saying that this is
right for everyone so if you want to continue on your journey, then by all
means do so but every single unsuccessful attempt you make, that's one more
Duo that someone can't enjoy. That's my 2 cents.
