Launch the Multimedia Product Tool. The interface might be in Chinese, so you may need to use translation tools or follow a video guide to find the correct options. 4. Select the Firmware

Most X12 Plus units run on an Actions Semiconductor (ATJ) chip or a Rockchip variant. Firmware is rarely cross-compatible between these two. Top Custom Firmware Options 1. RetroFW (The Gold Standard)

While CFW drastically improves performance, the X12 Plus chip still has hardware limitations. For heavier PS1 games like Tekken 3 or Gran Turismo , open the emulator menu (usually by pressing Select + Start ) and turn on to maintain fluid audio and controls.
