A handful of years back, JC Penney made a huge deal about stopping this practice in their stores, where everything is on “sale” all the time. Sales plummeted even though the actual product prices stayed the same. They immediately reversed course.
Hard to blame them. Human brains are weird.
RetroArch is super popular and available across many systems, with a bunch of open source frontends for it. I have it on a Raspberry Pi, a Mac, an OG Oculus Quest, playing everything from MAME to PSX.
