DJ_GLiTCH Tip: Auto-switch resolution per game (May 6, 2025)

Auto-switch resolution per game (Luigi’s Mansion example)

By: DJ_GLiTCH

Date: May 6, 2025

Affects: Windows • TeknoParrot

Source: link

This code will dynamically change your monitor resolution if you have issues with games not being fullscreen or scaling incorrectly.

The code is stored in Launchbox emulator settings, under "Running Script" for Teknoparrot.

You'll need QRes.exe to make this work too (download link below). No install required, just copy QRes.exe into a folder you'd like to save it in.

Change the directory path in the code to suit where you have saved QRes.exe

Note: 1: The resolution and refresh rates are tailored to my monitor (4k 240hz). If you have a different refresh rate you want to use across all resolutions, change /r:240 to be what you need (240 = 240hz, 120 = 120hz, 60 = 60hz, etc.). The resolution is self-explanatory, and is in the ChangeResolution(x,y) loop section.

Note 2: I've only populated Luigi's Mansion so far but will add more games later, and will try to make the original resolution and hz more smart (currently I hard code 4k 240hz).

Note 3: If you have any issues, try setting your display scaling to 100%.

#Persistent

; Function to change the resolution
ChangeResolution(width, height) {
    RunWait, "C:\xxx\QRes.exe" /x:%width% /y:%height% /c:32 /r:240,,Hide
}

; Run when Luigi's Mansion starts
Loop {
    Process, Wait, VACUUM.exe
    ChangeResolution(1920, 1080) ; Change to the desired new resolution for the game
    Process, WaitClose, VACUUM.exe
    ChangeResolution(3840, 2160) ; Restore the original resolution for the monitor
}

ChrisTucker Tip: Stabilize RS3 Reapers config drift (June 15, 2025)

Stabilize RS3 Reapers when MAMEHooker config drift happens

By: ChrisTucker

Date: June 15, 2025

Affects: RS3 Reapers • MAMEHooker • HOTR (untested)

Hello! @dea7hsmiles thank you so much! me and my wife love playing all these awesome games. I have some tips for peeps like me with RS3 reapers

Some tips for peeps with RS3's, who use only mame​hooker and who suffer from occasional "config drift" e.g. gun 1 recoils gun 2, gun 2 and gun 1 fire at the same time etc. This may work for HOTR if you run those scr​ipts instead but that's untested my end

If your guns start to get confused try this (assuming everything was working before on all systems and com ports set to correct port for each device):

1: Reboot PC 2: Go into launchbox/emulators/demulshooter and check that guns are in correct player e.g. gun1 registers as player 1 and gun 2 player 2 3: Config lightguns from gun software in tools folder, do each gun 4: Run "set emulator to mame​hooker scr​ipt" - as administrator 5: Run "config guns for RS3 reapers" scr​ipt - as administrator

Everything should now work if it did before
