Tutorial RPGM RPG Maker MV HDR Compatibility Fix

[ArcFlight]

Example of what you might see with Lust Doll Plus.

If you have an HDR monitor and have HDR enabled, you might notice some (all?) RPG Maker MV games look dim with whites looking grey.

RPGM MV, at the time of writing this, uses Chromium 65, from NW.js 0.29, to display the games. You can check this out in games with the console enabled by pressing F8 or F12 and entering process.versions into the console.

This version of Chromium is old (Jan 2018). And since Chromium 64 added HDR support, appears to be a bug in 65. HDR appears to have been fixed in Chromium somewhere between 65 and 86.

After some limited success Googling, I've discovered two ways to fix this.

Fixes:

1. Force sRGB rendering. (Easy)
2. Update NW.js. (Easy to Hard, may break the game you are updating, may also improve performance)
3. Disable HDR in Windows HD Colour settings every time you run an RPGM game. (Easy but stupid )

Option 1, Forcing sRGB:

1. Open the directory with the game executable in it.
   1. Mac users... rename Game.app to just Game so you can open it as a directory, then navigate to Contents/Resources/app.nw.
2. Open package.json (might just be named package).
3. Add the following line "chromium-args": "--force-color-profile=srgb".
   Your package file might be significantly different depending on the game. Just add it before the final curly brace }.
   Make sure the previous line has a comma! See the GIF below if confused.
4. Save.
5. Done. Launch the game. Enjoy.

Option 2, Update NW.js:
This option may boost game performance due to using a newer version of Chromium. It may also break the game.

1. Back up your game or prepare to re-download it in case you break it!
2. Open the directory with the game executable in it.
3. Download the appropriate version of NW.js from

   See the spoiler for a simpler choice of what to download.
   • Pick one starting with nwjs-sdk-v0.49.2 if you want to enable the console.
   • Pick one starting with nwjs-v0.49.2 if you don't want to enable the console and save some disk space.
   • On Windows, pick one ending -win-ia32.zip.
   • On Mac, pick one ending -osx-x64.zip.
   • On Linux, pick one ending -linux-x64.tar.gz.
4. Extract the contents of that zip (or tar.gz) overtop the game, replacing any files when asked.
5. Delete Game.exe, Linux and Mac users skip to step 7.
6. Rename nw.exe to Game.exe.
7. Done. Launch the game. Enjoy.

helped figure out what was to blame.

Thank you for this!!! I've literally lost some LP over this. Just got a new screen which is HDR compatible. Everything was looking good except for rpgmaker games. I did the first option. Annoying but rather that, than risk breaking anything

hero legend among man, thank you bro

Thanks a bunch! Ran into this issue today after getting my new OLED monitor and this was one of the first posts on Google for this issue.

Option 1 worked great!

 

[Schimoon2]

Option 2 worked on Genesis Order (1.05)
This is a huge step forward in image quality, thanks a lot

 

[Msai]

Thank you!! Option 1 Worked on RPG MV

I also chose the first option, it works very well on Windows 11!
Thank you!

I can't remember why it was that specific version. I think newer ones caused some kind of issue.

You could try newer versions, but obviously remember to back up or keep the original game download. If newer ones do work fine, I'll update the post.

Not sure why that might be. It could, for what ever reason, already be using a newer version. But then you wouldn't need to update it anyway.

You could try the SDK version. I highly doubt it would fix it, but if you opened the console, you might find out why the sound is not working.

You'd probably be better off sticking with just using option 1 to get HDR working.

Thanks. I check .49 and .105 and still nothing. Just turn off HDR in win setting and screen is Ok, not entirely dark, but for me its partial solution

Thank you so much for this guide! This stuipd bug bugged me for years..
I'm on Windows 11 and option 1 worked like a charm (so I didn't try the second one). The often mentioned option to turn off HDR globally isn't an option for me at all, since then I also would have to change the brightness of my monitor in its settings.

There is a way to rise resolution in rpgs games? maybe somewhere in nvjs files? Im looking in Treasure if Nadia files but cant find anything, and i have no more ideas...

It doesn't appear that there is any truly easy way to do that. Unless the game has a plugin (in which case you should see an option in the settings!), it can mess up the game, or at best make everything blurry. Pixel art suffers the worst from scaling too.

You might be able to use Windows Magnifier. It apparently has a mode that can remain static. You could also try this to forcibly resize it, but again, it might blur or make the UI all broken.

The best option would be to appeal to the developer to add a plugin or option for resolution.
