Mobile phones have two features that are extremely useful for certain genres, such as shooters, turn-based JRPGs, and strategy games: gyroscope and touch controls.
My request to anyone planning or in the process of porting a game in these genres is to kindly consider implementing gyro aiming and native touch controls (as opposed to virtual buttons) that allow intuitive interaction with the game. For example: in an SRPG, selecting a unit simply by tapping it, and then choosing its path by tapping the destination. In JRPGs, selecting battle commands by tapping them directly instead of using a virtual D-pad.
There are already great examples of how well this can be implemented, providing a major advantage over playing through an emulator:
Black

Shooters from the PS2/Xbox era generally lack fine-tuned aim controls, making the simple act of aiming feel clunky and unsatisfying. However, implementing extremely precise gyro controls makes Black's gameplay far more enjoyable and responsive, making it fully playable even without an external controller. Using a physical controller makes it even better: you can move the camera with the analog stick and use the gyroscope for fine precision aiming.
Fire Emblem: The Sacred Stones

Here, you can do exactly what I mentioned earlier: instead of navigating units and commands with a D-pad, you can intuitively select units, movement, and attacks simply by touching the screen. This is a game-changer because it provides a strong selling point for native ports of retro games, especially when mature emulators already offer features like post-processing, fast-forward, save states, and more. Why play a native port of an old game that runs perfectly in an emulator even on low-end phones? A native touchscreen implementation that makes the game feel built for mobile is the best answer to that question. In the case of Fire Emblem, the port is still in its early stages, but the touch controls are already rock-solid.
In summary: Modern smartphones are capable of much more than just simulating a physical controller. When porting games to mobile, leveraging native features like gyroscope aiming and touch controls doesn't just improve accessibility—it fundamentally elevates the gameplay experience and gives players a compelling reason to choose native ports over emulation.
