I love the 2-player Red/Blue setup for Arkanoid/Puchi Carat but I would definitely rather avoid dealing with 30-year-old arcade hardware and I'd 100% much rather just wire up existing solutions (TurboTwist, Ultimarc, GRS, etc.) for spinners and plunk down a similiar-designed third party repro knob.
Are there any online shops that sell such a knob? I'm basically talking about this style:
I wouldn't even mind if the inset is blank and I'd have to print/cut my own blue/red vinyl labels. Just asking in case there's already a solution for this need that I haven't personally been able to find online.
