---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- Compatible with Game Boy and Game Boy Color cartridges, Game Boy Advance cartridge compatibility (beta version) via open source software (because it is an emulator, some games may not launch properly) 720p 4:3/16:9 aspect ratio switchable USB controller (cable length: 180cm) x 1, HD cable (cable length: 90cm), Type-c cable/AC adapter included (cable length: 180cm) Includes memory card slot for firmware updates Manual (English)
