Lightgun games (Konami Justifier) and 16:9

[Former user]

Original [issue 174](https://code.google.com/p/genplus-gx/issues/detail?id=174) created by rafalapso on 2011-06-30T01:03:54.000Z:

What steps will reproduce the problem? 1.Put wii in 16:9 screen ratio 2. Load genesis plus GX 3. Load any game with Konami Justifier support (Lethal Enforcers 1 is a good example) 4. If the scaling option is in SCALED or Original (16:9) then the wiimote pointer and the ingame gun position will not match. If the scaling is in Original (4:3) the pointer and the gun will be in the same screen position

What is the expected output? What do you see instead? The screen scaling in 16:9 doesn't match with the wiimote pointer. Only does work in 4:3 scaling.

What version of the emulator are you using (official, SVN revision,...)? 1.5.0 official

Please provide any additional information below (Video settings, Console region,...)

This is caused by the fact I forgot to handle GX scaling & offset when calculating x/y position before rendering the pointer.

When original(4:3) aspect ratio, i.e without 16:9 correction, is selected, GX scaling is disabled so pointer is drawn at the correct position but I guess the same error occurs, no matter the chosen aspect ratio, if you modify the x\_offset and y\_offset screen value...
