If all methods failed, please consider use tools like systemd or “Session and Startup” to force running command fcitx after startup.

EmuDeck has a list of supported emulators.
Many games can be downloaded for emulators, and played on various platforms.
Arch Wiki contains a section around gamepad.
Keyboard can handle all gamepad functions, no mouse required.

I do not want to buy a physical console like Xbox Series S along with a strange HID to gamepad adaptor. It will not accelerate the development of cybergod.
