I got the Yellow RGB20S and I'm so excited and thrilled to have it! I'm disabled and have Agoraphobia, which makes leaving my apartment difficult. I figure this will help distract me from my anxiety/panic when I have to take the city bus places. Idk if this is standard for this device, cos I ordered from a third party, but mine came with ArkOS installed and has 20,000 games on it from 20 different emulators, from NES to PSP. And I saw a video on YouTube of someone putting Stardew Valley on it through Port Master, which has me super excited!😍 im actually pleasantly surprised at the quality of this device as well, considering its just another cheap Chinese emulator game system. While its obviously not a high end handheld, it does feel like a quality build, and has about as much heft to it as a Gameboy Color. My only question is that it has two USB-C ports on the bottom of it. Which one is the charging port? The one labeled DC, or the one labeled OTG? And does the indicator light color change from red once it's fully charged?
