Someone just traded this thing into my store 5 minutes ago. I've never seen it before in my life. I searched around on google and found multiple links about a PS1 version...most mention that an N64 version was coming, but I couldn't find any info.
Here is a link I found for the PS1 glove:

Any info on rarity/price would be appreciated. Thanks.
