Fabricio Breve 260e0a1903 Fix lightgun position calculation for vertical aim (#176) ...

* Added support for loading Master System BIOS files.

Master System BIOS files can now be used to boot games and play built-in titles.

* Fix lightgun position calculation for vertical aim

The Master System core exhibited a vertical aim deviation with the lightgun, even when properly calibrated.
The offset was zero at the top of the screen but increased progressively toward the bottom.

This commit corrects the lightgun position calculation logic, ensuring accurate aiming across the full vertical range of the screen.
