~Aloha Bonovox400, i'm glad you got it to work...I'd say use all dvd-r (verbatim, sony, memorix to name a few) which work well with wii. In addition, load between 2x-4x when using the Imgburn all all your items. I've seen at times where people had to burn at 1x to get certain games to work. Remeber, you have to make sure that the game is in the same region otherwise it can brick your wii when you upload. Since you have a wasabi zero it should be: region free enabled, enable import update blocker, disabled domestic update blocker. Just double check your settings as a precaution.
Regarding Madworld and Smash brothers those games were at higher wii versions so certain people had to add ios (not the modded ppl). Modded people just need to update their wii with either the orginal or higher lvl games to get the ios in their wii to play the games. Once again you have to have the correct
region games to upgrade or you can brick your wii. Some people use regionfrii software to change the region of their game like from pal to ntsc but I wouldn't advise on it unless you do alot of research. But if i'm not mistaken if you open up the iso in the regionfrii template it will show the present region of the iso that you burnt or copied.
The wiimotes currently wiimotes are made from a US company Analog Devices STMicroelectronics because their wiis are not as sensitive as other makers. Maybe you just got a really sensitive one. Anyway, they are looking into having motion sensing chips to attach to the wii to have a better response from it. So, answer your question no change in sensitivity in the current wiimotes. You can try re-syncing them both:
Try these steps:
Turn the Wii console power OFF by pressing the POWER Button on the front of the console. Unplug the power cord from the wall outlet for a few seconds. After a few seconds have elapsed, plug the cord back into the wall outlet.
Turn the power of the Wii console ON. When you see the Health and Safety screen, open the small flap on the front of the Wii console to find a red button labeled "SYNC." Press and hold the SYNC Button down for 15 seconds. This will clear all the syncs on the Wii, allowing you to get a clean start to begin the process described below.
After holding the SYNC Button on the Wii console down for at least 15 seconds, you can now "re-sync" your Wii Remotes:
With the first Wii Remote you wish to sync, remove the battery cover on the back of the Wii Remote to find a small red button just below the batteries.
Press and release the small red button just below the batteries on the Wii Remote; the blue lights on the front of the Wii Remote will blink.
Quickly press and release the red SYNC button on the inside of the white flap on the front of the Wii console (picture).
When the Player LED blinking stops and stays lit, the syncing is complete. The LED that is illuminated indicates the player number (1 through 4).
This sync procedure (steps "a" through "d" above) must be followed for each additional Wii Remote added to the system.

Hope this will help if any,
