I recently got back into playing Pop n on my Ransai. As the songs got harder, the more my Ransai would scoot on me on the stand.
When I had played before on the PS2 I had never gotten really good at it so the easy songs wouldnt have the Ransai scooting around nearly as much.
Recently I've been decent enough to play up to level 23 at the scooting has gotten to where it seriously effected the game play. I tried blankets and a number of other things before I finally came across this.
It's called Shelf Liner and I was able to pick it up at my local Dollar Tree. The best parts are it only costs 2 dollars (you need to buy 2 shelf liners) and the shelf liner happens to be the exact width of the ransai controller. Simply unscrew all the back screws on your ransai controller, screw in one side's farthest screws into the shelf liner, stretch it across your ransai, screw in the other sides farthest screws, then screw in all the rest of the screws. Cut off the excess and your ready to go!
The other sheet simply drape over your stand if you use one. Both shelf liners grip onto each other. I would have to purposefully knock over my ransai now for it to move!! The mod also works great for on tables if you use it. Your ransai will hardly budge anymore! Plus it comes in many colors!
Also, I havent tried this on a DASC, but I assume that it would probably work the same.
Let me know if anyone tries this out!
