ok some of you have probably heard of a rhythm game called soundvoltex.
it's only released in the japanese arcade and it uses always-online DRM so the chances of seeing an arcade here are close to zero.
Some Japanese guy made a clone called "Kshootmania" but it's closed-off, windows only, has performance issues, it's written in some weird japanese-only programming language called HSP (hot soup processor) and worst of all, this guy was forced by konami to implement DRM into his latest release rendering these songs useless:
https://github.com/Schinizer/kshootmaniasdvx/releases (all sdvx songs ported to ksh format)
they can still be played with this old version of kshootmania but as we all know, this isn't a good long-term solution.

So I'm currently co-operating with some people who did a basic kshootmania clone in C++
it's opensource which means DRM is pointless as anyone can just rip it out again, unfortunately it's not mature enough to be a good replacement of kshootmania but we're working on it!
if you have any interest in this game, and know how to program give us a helping hand, otherwise stay tuned!
