Ah, the ones
here?
I wonder if the "+" in the filename is the issue. I'll reupload, and if that doesn't fix it (EDIT: it didn't), I'll check with bustin98 as to if +s are going to be a problem.
EDIT: That was a quick fix. They work now that I've removed the +s. I wonder if there's an easy way to hunt down any other maps with weird nonalphanumeric characters that might be troublesome. I'm annoyed that Windows Explorer can't search for "+", unless there's some trick to getting it to search for unusual characters.
Thanks for letting me know, jmo!
Also for showing that the registration for the forums works...
By the way, everyone should download this on the Wii U Virtual Console before the Wii U eShop gets taken down in less than a year. The Wii U Virtual Console version includes all those World e+ e-Reader stages! Sort of makes it the definitive version of Super Mario Bros. 3 (though those extra stages have elements from Super Mario Bros. 2 and Super Mario World)...
