We upgraded the X28 firmware on June 11th. The content of this upgrade includes: repairing L2 R2 to run normally on Minecraft, adding Dolphin, Daijishō, deleting PlusSnes9, updating AetherSX2, and configuring the emulator.
If you need, you can download the firmware to upgrade your X28. Note that before the upgrade, please try to understand how to operate the steps to avoid the console from being unable to start during the upgrade process.
