It had been a very long time since I played my Wii. I got my Wii-U on launch day and haven't played any Wii game since. So I figured I'd get the Wii controller and figure out how the Wii-U works with Wii games. I wanted to play with my uDraw. Found it, it was in the garage. Found all 9 games for it as well (it was with the Wii, which was in the pantry.) I decided to change the batteries, so I undid the Wii's battery cover. One of the batteries had corroded. White stuff oozing out of it. So I took the batteries out, wiped away the white stuff that was on the battery plug in hole, went to get batteries. Doh. I only had one AA battery left. The Wiimote uses 2. So I'll have to wait until I go to the store again and get a few AA batteries so I can test the Wii on the Wii-U. I played New Super Mario Bros. U again. I got to level 8 before I said "this is too hard." I've decided to give up playing it. I had to have the game beat two levels for me after I died a whole bunch of times. I wish they hadn't have made it so f---ing hard!
