Interview With LaserActive Emulation Creator: Nemesis Sep 15, 2025

Show notes

Here's an interview with Roger, aka Nemesis - The developer who reverse engineered the Pioneer LaserActive and created the first emulator for it! It was a blast hearing Roger's whole 15-year journey into making this happen and I think any retro hardware (or Domesday) nerd like myself will love hearing it. We get a bit technical, but I think most people should be able to follow along. As always, these long-form conversation are available as a video above and on all podcast services - Just search your favorite app for "RetroRGB Nemesis".
