I wouldn't think that memory foam mattress topper would be a good choice in this case. It tends to compress quickly, especially in response to body heat, and once compressed it is going to offer less vibration resistance than other materials. The "cheap" kind of mattress pad tends to wear relatively quickly as well. Other types of higher density urethane foam might be appropriate, but the kind rated for sleeping on is unlikely to be useful. Have you considered using carpet pad instead? It's specifically designed to absorb impact in order to increase the life of carpet installed above it. I would think that would make it useful for your purposes. You need such a small amount of it, I'd think that a home improvement warehouse or carpet showroom/warehouse would sell you a remnant for next to nothing. With the cost being so low, you could probably get a few different types and test them all to see what works best for you.

See: https://remywiki.com/DanceDanceRevolution_credits While the English wikipedia page doesn't seem to list credits for the game, pages in other languages may (example: Spanish Wiki Page ). While I can't seem to confirm the full list as a single list elsewhere, RemyWiki does match to the wikipedia list on the elements where they overlap (thus supporting its accuracy), but offers a wider range of credits. Cross-referencing the individual names does provide further sources confirming their involvement with the projects (example: DDR designer Kanako Yonezawa on MobyGames), in the same roles listed by the remywiki page (though it should be noted that the secondary sources I found did not necessarily confirm association with the first game itself), so the list does seem to be correct. In regards to answering the specific question you presented, Yoshihiko Ota was the producer in charge of the project, Katsunori Okita and Kazuya Takahashi were the directors, and the following were designers on the project: Nobuo Tomita, Eiichi Yoshioka, Yukiko Mizoo, Yutaka Sakaue, Mitsuo Nagamoto, Tomohiro Ota, Kazushi Hasegawa, Takashi Inubushi, Akira Iizumi, Yoshiko Oiwa, Kanako Yonezawa. If you're looking for general development background, The Ringer has a decent article on how the first DDR came about.

This was going to be a followup comment, but I realized it's probably an answer. On step 18, your right foot is on the right arrow. On step 19, use your left foot to plant on the up arrow. On step 20, pivot on your left foot and use your right foot to plant on the left arrow. On step 21, pivot on your right foot and use your left foot to plant the down arrow. On step 22, pivot on your left foot and user your right foot to plant on the up arrow. You're almost neutral again, unfortunately, you must immediately reverse your spin across the down arrow. Hope this helps!

You're right, you should be pressing the panel at the exact moment that the arrow covers the arrow at the top. The game gives you a grade based on how well you timed the step. The grades are "Miss", "Boo", "Good", "Great" and "Perfect" (and an ever higher "Marvelous" rating in newer iterations). You want to aim for Great or better. The exact grades and timing windows vary a lot from version to version, and are usually wider on the console versions than they are in the arcade. The timing window for the best ratings (Perfect, Marvelous) is usually on the order of ~20-40ms (source: StepMania wiki), or about 2-4 frames. The key to hitting the arrows precisely is stepping to the beat of the song, as opposed to reacting to the arrows. If you're reacting to the note, you're already too late. If you look closely at the arrows at the top, they are blinking to the beat of the song. This will help you feel the rhythm, and on easier difficulties you'll almost always press a panel at the moment the arrow blinks. As the songs get more difficult, you'll have to step on half-beats, quarter-beats, and even more complex rhythms. It helps if you have some music experience, but the clonk of your footfalls should sound even, like a drum playing. Assuming the dance pad is in good condition, there should be no noticeable delay from when you hit the panel to the game's response. If you're playing on a home console, the included plastic mats are usually not particularly good and can break over time, causing unresponsiveness. If you're interested in jumping down the rabbit hole and getting into DDR, it might be worth investing in a better mat. The ones with the foam inserts are a good step up from the cheapo ones without being particularly expensive: DDR Foam Mats If you are playing at home, many modern TVs can introduce some delay. Make sure your TV is set to "Game" mode, if it's available. Also, the DDR console versions often have a "sync" setting in the options that you can use to fine tune the timing.

After doing some quick research I have determined that you should be able to do this. If your guitar is wired, try out this adapter. Someone on this thread has confirmed that it did in fact work for them using a PS2/PS3 Peak Starpex Guitar. If whatever reason the thread link breaks down, here's what was said: Hey y'all! I bought this puppy based on the reviews I mentioned above, and it works perfectly with my PS2/PS3 Peak Starpex guitar. This thing is awesome!!! (p.s. despite the timing of my post, this is not an april's fool crack) and here is an image of the product: Playstation 2 PS2 to Wii Controller Adapter (13.5CM-Cable)

That's a DE-15 connector, the same kind as used with VGA cables, but it's not a VGA connector. VGA cables only carry analogue video, they're not used to connect any sort of controller. Your dance pad has a proprietary connector that happens to have same shape as VGA connector, but serves a much difference purpose and isn't compatible. Any VGA to USB adapter you might find would essentially be a capture card. Connecting your dance pad to such a device would be as useful as connecting your pad to a computer monitor or video card. Unfortunately this means in order to connect this to your PC you'll probably need find the original adapter. Since it's a proprietary interface for an obscure and obsolete game controller finding a third party replacement isn't going to be easy. I found these two control boxes that might work as they both use 15-pin connectors, but neither lists any model of Red Octane pad as being compatible: Dance Dance Revolution Control Box for PS/PS2 Metal Dance Pads (15-pin male) Dance Dance Revolution 4-in-1 Control Box for PS2 / Xbox / PC/ Wii with Blue Buttons (15-pin male) You'll may also need to get a PlayStation controller to USB adapter, but these shouldn't be too hard to find. However, don't confuse a PlayStation 2 controller to USB adapter with a PS/2 to USB adapter. The former device is for connecting controllers that use Sony's proprietary interface to a PC, while the second device is for connecting keyboards and mice that use the legacy PS/2 interface.
