The connector is where an n64 cart plugs in. Most likely to use the boot chip. There are 5 or so. Having 5 games total isn't so bad, plus maybe it can emulate them. the z64 did.
This is good news, if it works well and isn't abandoned and all.
Does it work with:
Conker's Bad Fur Day
Pokemon Stadium 2
Resident Evil 2
That one Ogre Battles game, I think.
There might be save issues with some games. And some will surely need to be hacked. But it will probably function like a v64jr, without the need for batteries.
Good news, keep it up. Any estimated release date?
