Well, it appears there's a second part after all, despite the battery cutting out. I posted part 1 back in January.
So what am I playing Zelda 2 with?
I'm using a Messiah wireless NES controller.
Remember Messiah? They put out the Generation NEX NES clone a few years back. It was a much-hyped, slick-looking system back in 2005, and promised built-in wireless, dual-mono audio output, and full compatibility with both NES and Famicom games and accessories.
And then it came out and turned out to be running the same damn crummy third-rate NES-on-a-chip as every other Chinese clone.
And so Messiah faded into obscurity.
Which is a pity, because despite the disappointing guts of the NEX, Messiah made some damn solid controllers. And while the NEX had a built-in wireless receiver, you can also use them on a legit NES with a dongle. (The gamepads, anyway; from what I understand the joystick doesn't work with a real NES. Don't know, never got one.)
The controller works well. It's solid and has a good weight to it; the buttons have a good response even if they're a little clicky.
The disc-shaped D-pad is a little weird but I haven't had any real trouble using it to play Zelda 2 -- I have a bitch of a time fighting Ironknuckles, but I don't think that's the controller's fault. I can see it being a problem on something that requires more four-direction precision, though.
It really is a pretty neat device and well worth the $50 Amazon's charging for a pair. (I got the Limited Edition set, which I see is now going for $175 used. I'm tempted to snatch up that $50 set and sell my limited set, but I do like the metal lunchbox.)
I'm kinda disappointed I never got the SNES set, because you can't get those anymore, but I'm seeing good reviews on the SuperRetro wireless SNES controllers. And they have good old-fashioned plus-sign D-pads, too, not discs.
Kind of a moot point, really; the state of SNES emulation and the now-standard design of its controller have meant I haven't hooked mine up in years.
