Quick example of the CLUB MED manip. Hold Select+A+B on the p1 controller while holding Start+A on p2 controller. You have to be holding all of those as the game boots up and during the entire player select screen through puzzle selection. It works with just A on the p2 controller but the window for getting it seems to be way bigger with Start+A.
Timing can vary a lot and there are a handful of puzzles you can get (MOISHE DAYAN is another common one) but Club Med seems to be the most common with this setup.
This is easier if you tape the controllers together or put the p2 controller on the floor and step on it strategically to hold Start+A. You do you.
Wheel RNG is wild.
Fun video of finding this manip (granted this is after weeks of experimenting with p1 and p2 inputs in emulator in 3 different NES Wheel games)
