Same as Rudy, I couldn't resist in the end.
IT'S ARRIVED !
I had to try it out on a couple games, tonight. Clearly, the stick on this thing is much more sensitive. Trying to pinpoint a distant target with the pistol in Jet Force Gemini wasn't easy at first. But the added sensitivity turned out a major ally on other games, like Pilotwings 64, where the accuracy is crucial. I must also say that it felt super comfortable playing Sin & Punishment
. Banjo-Kazooie also felt super comfortable to play.
However... I couldn't get my transfer pak to work with it on Pokémon Stadium 2 :/. That being said, I wouldn't want to play a D-Pad exclusive title like Pokémon Stadium with anyway, given the position and size of the D-Pad.
My unofficial controller pak had some troubles too. I could load my save files on Mystical Ninja, but not save for some reason... I couldn't tell if it comes from my specific controller (like a malfunction), the model itself being built to not recognize some controller paks not manufactured by Nintendo, the specific model of controller pak I use which has memory bank selector switches on it, causing the incompatibility with the new circuitry, or something else entirely.
My rumble pak works flawlessly though. All in all, I don't regret my purchase anyway.
