Except for 1 or 2 games (Gundam dualscreen 2players and Op. Ghost ringwidefor full screen are the only ones I have in mind right now) I try to avoid GameLoader as much as possible.
Mainly because I don't really have any visibility of what it's really doing and it was messing badly with DemulShooter a few years ago.
I usually manage to get exactly what I want with dgVoodo and/or DxWnd
As for Nomousy, it worked perfectly when I was using WIn7 but I have a lot of trouble with it since I updated to WIn10 on my gun config
Operation Ghost - I use the below Autohotkey to load it full screen without TP or GameLoader
SetTitleMatchMode, 2
DetectHiddenWindows, on
Sleep, 1000
Run, C:\Users\User1\LaunchBox\Emulator\demul light gun\DemulShooter_v8.5.7\DemulShooter.exe -target=ringwide -rom=og ; Pathway to demulshooter ignore it says Version 8.5.7 I cannot be bothered to change all my shortcuts it is newest version
Sleep, 1000
Run, C:\Users\User1\LaunchBox\Games\Sega RingWide\og\gs2.exe ; Pathway to Operation Ghost game.exe
; The next bit resizes the window to FULLSCREEN on my screen (1920x1080)
WinWait, ahk_class A
WinGetPos, WinPosX, WinPosY, WindowWidth, WindowHeight, A
WinSet, Style, -0xC40000, A
WinMove, A, , 0, -20, A_ScreenWidth, 1100
;Hide Windows Task Bar and Start Button. (Remove the following two lines if you don't want that behaviour)
WinHide ahk_class Shell_TrayWnd
WinHide Start ahk_class Button
; moves the system mouse cursor to the very corner to just make it tidy and blocks it from moving
MouseMove, 9999, 9999
BlockInput MouseMove
Sleep, 3000 ; needed on my machine to make nomousy then work
Run, C:\Users\User1\LaunchBox\No Mouse\nomousy.exe / hide ; pathway to nomousy
; below section upon pressing Escape turns off wiibar via a shortcut, closes Touchmote, closes game, runs nomousy again to turn mouse cursor back on, kills no mousey so it works again the next time, this is needed on my computer might not be on yours, allows mouse to move and repositions in centre of screen you will need to change the figures for your set up
$Esc::
{
Run, C:\Users\User1\LaunchBox\AutoHotkey\light gun\off - bar and touchmote.lnk ; most likely not needed for you
WinWaitClose, Touchmote ; most likely not needed for you
Send, !{F4}
Send, {Esc}
Run, C:\Users\User1\LaunchBox\No Mouse\nomousy.exe
Run, taskkill /IM "nomousy.exe" /F
BlockInput MouseMoveOff
MouseMove, 960, 540, 0
}
Exitapp
This might help some people - I run a bat file to start Wiibar and Touchmote before this AHK and the "Run, C:\Users\User1\LaunchBox\AutoHotkey\light gun\off - bar and touchmote.lnk" turns them off and then does the other bits. So it is going to need some butchering for it to works for others - it isn't going to work straight out the box.
Nomousy
For nomousy on Windows 10 I find if after you run it to hide and then run it to make it reappear if you then kill process as shown above it works the next time as well- there is no process to close so I don't know why it works but it does.
Cheers
