Well, there's a popular community around it, the Lost Media Wiki (LMW), https://lostmediawiki.com/Home, they are known for having a lot of media which tends to discovered and people go on searches for it. If you're using reddit, there's /r/lostmedia or r/tipofmytongue which you can use to get started

Maybe you'll have some luck here? https://flashmuseum.org/

Or: https://flashpointarchive.org/ but maybe you've checked those. Hope you find it!!

omg are you talking about FlashFlashRevolution? I loved playing that back in the day

nooo it used to be on this website that made you install a really sketchy toolbar in order to play their games, I checked on flashpoint too and its not there (LOOOVE flashpoint btw!!)

this site had a bunch of other older arcade games like track and field and this flash version of frogger with oddly realistic looking graphics, I did find that version of frogger on flashpoint, though!

the front page of the site's been archived and they have a animated carousel thing showcasing the games they had/screencaps of the games, DDR is one of them! https://web.archive.org/web/20100420040630/http://retrogamer.iwon.com/home.jhtml

another page promoting the game and their super sketchy toolbar https://web.archive.org/web/20100414140256/http://retrogamer.iwon.com/dl/index.jhtml?theme=ddr

definitely go with reddit. theres always someone that knows exactly what youre looking for, r/lostmedia like the other person mentioned but also old web subreddits might be able to help. https://www.reddit.com/r/FlashGames/ has a bunch of game archives

im with the people saying reddit!! r/lostmedia is def your best bet. That, or the LMW forums.

Sometimes you have to double click the play button to play the music if you're just opening the webpage lol

Of course, thank you!! I'll link you back as well! :DDD

Im going to be doing 3D models for VrChat/Vtubing, and Digital illustration so stay tuned if you're interested in that kinda stuff :3
