Retroid Pocket Classic Retro Handheld Game Console, 3.92" OLED Touchscreen, Portable Android Gaming Handheld with 6+128GB, 5000mah Battery, Android 14, WiFi 5 Classic Games Console (Classic 6)

You can get it here on amazon. I mainly got the 6 button version because I love arcade games. If you aren't big on arcade/Sega saturn then get the 4 button version. Also check out Retro Game Corps for his in depth tutorial on the 6 button version

Not sure if you are still in the market but The official Retroid store on Amazon has atomic purple in stock right now. https://a.co/d/061D7nzV
