We just ordered a DDR mat that's supposed to actually let us play our old DDR games in the PS3. It came with instructions written in an interesting translation of English.
An excerpt from the warning section:
V, matters needing attention
1, do not be please in the high temperature, moist and under the multi-dust environment to use
2, Please not will dancemat to put the place which iwll expose to the sun in the solar storm.
3, guarded against uses the non-neutral solvent to clean this.
4, please do not have to make an effort to twist, pulls the electric cable line, in order to avoid the ties damage.
and my favorite:
5, the child, the old person and bodily illness carry on the game, avoids the period of revolution excessively being long.
