Here is another video, though this time it is not a comparison, as I think a comparison would be hard to do, but here is the level 5 boss of Yoshi's Island, showing off the enhanced rotation allowed by the GSU-2.
https://youtu.be/9x4gCWUbB0MThis was my first time fighting this guy, and I suck at platformers in general, so don't razz me too hard, but hey, um, you get to see more of the rotation effect, haha.
Edit: Wow, just watched a video of someone beating this boss competently. Can't believe it didn't occur to me that I could pound the pegs while the raven was in motion instead of having to wait for him to stop.
Sort of reminds me of my first time playing Portal 2. I got to Wheatley and somehow was under the impression that he had completely surrounded himself with the bombproof shields in his third phase. So I thought I had to juggle a bomb with some portals and then pop a portal under him when he lowered his shields so the bomb would hit him, and I did in fact beat him that way. I felt like such a dummy when I watched a video of the boss fight afterwards and saw that he was completely unguarded from the rear the whole time, haha.
Edit #2:
I'm hoping for In-Game-Reset to be implemented for GSU-1/2. I don't like constantly using the power button on my system, I want to preserve it's functionality for as long as I possibly can.
Here is how I feel about this. Firmware v0.1.4 was released around the same time krikzz started selling these. Here is ikari's update on this firmware at the time:

Adjust Cx4 timing to be closer to the original (Mega Man now defeats the boss in attract mode in Mega Man X2; test this against some emulators for fun.
)
Well, I did try it against some emulators, and I was amazed. And as great as GSU support already is a little over a month in, I want the best for our beloved SD2SNES.

My feeling is that you can do things like in-game hooks and cheat codes through emulation (and emulation is absolutely ideal for things like savestates, though I sort of wonder now if the Super Nt could do proper, emulator-like savestates on an SD card---whoa!), but accuracy requires a much more expensive, powerful machine than your typical plug-and-play emulator-in-a-box. So it's for that kind of thing that FPGA solutions shine.
