Do not press the power button to force a shutdown. This will cause data loss and system damage, resulting in the inability to boot. Please be sure to press START on the main interface, find Exit, and then select Shut Down.2. The battery display is not very accurate due to voltage issues. The red light lights up when charging and goes out automatically when fully charged.3. Unable to start after turning on/When the yellow light is on: If the machine cannot be started and the yellow light is on, you can press the power button for 10 seconds to force shutdown. After the yellow light goes out, recharge and turn on again later. The main reason is insufficient voltage, which can be solved by charging, but the possibility of damage to the system card cannot be ruled out.4. Game crash/stuck problem: If the game crashes or freezes, you can try to switch the game emulator core. In the game directory interface, move to the game directory where the problem occurs, press SELECT, find Edit Game Elements, and find Simulation device, change other emulators, find the core, change other cores, save, and try to enter the game again. If it still doesn't work, you can continue to switch and try.5. Because there are many games, some games may not be playable due to different eras and different emulator operation methods.6. When there are only 5 games in all: RGB20S is divided into two card slots: 16G system card and game card. The system card does not come with games. When the game ROMS is set to the system card, only 5 games will be displayed. At this time, we turn on the computer. Finally, find the OPTIONS simulator, click on the ADVANCED file after entering, and after entering, move to the bottom STWCH TO SD2 FOR ROMS to switch to 2 cards, which is the game card.Specification:: PowkiddyModel: RGB20SOS: Open source linuxDisplay: 3.5-inch 640*480p IPS screenCPU: RK3326 Quad-core, 1.5GHzRAM: DDR3 1GBWiFi: External WiFi, 2.4G/5GTF Card Slot 1: System card, support 16GB-256GB, 16GB system card includedTF Card Slot 2: Game card, support 16GB-256GB, 64GB game card included (or 128GB game card included optional)Speaker: 2WEarphone Jack: Standard 3.5mmBattery: 3500mAh lithium batteryPlaytime: about 8 hoursCharging Time: about 2 hoursCharging Power: 5V 2APower Consumption: 2W/hColor: Orange, White, Black, Blue, Purple (Optional)Item Size: Approx. 12.0*8.3*2.1cm/4.72*3.26*0.82inItem Weight: 170g/5.99ozPackage Size: 13.4*12.0*4.6cm/5.27*4.72*1.81inPackage Weight: 277g/9.77ozPackage List:1 * Game Console1 * Type-C Charging Cable2 * DIY Tiger Sticker1 * User Manual (English/Chinese)Package List:1 * Game Console1 * Type-C Charging Cable2 * DIY Tiger Sticker1 * User Manual (English/Chinese)
