Summary 06042: golgo13, g13knd: Gun aiming is broken
Description Gun aiming doesn't work. The game crosshair moves erratically as you move the MAME crosshair with your input device (tried with mouse and with keyboard separately). Therefore, with a broken input, the game is unplayable.
Steps To Reproduce You can see the game crosshair in the stage select screen, or in the gun calibration screen.
To access it, press F2 after the boot to enter service mode, then use the P1 up/down controls and P1 button 3 to enter the gun initialize menu.
Additional Information The first actual playable regression version is 0.154, since 0.153 is affected by 05501.
Regression Version 0.153

Confirmed, SDLMAME64 on Linux/x64 0.165

It's actually worse than just the calibration. The guns are completely and totally off in the game once you attempt to calibrate them, or even if you use an existing, calibrated NVRAM; in its current state the game is completely unplayable as no targets can be hit.

You're right. I thought gun calibration was necessary, but in MAME 0.152 and previous, the gun works fine even without entering service mode. So I've updated the report accordingly. Sorry for the inconvenience.

This bug seems to be fixed in the 0.185 version.

Just retested. Actually, both games are working well since 0.177. So this can be marked as resolved.

Not sure who (and which commit) fixed them, though.
