Are the scripts working for you with mpv 0.33+ ?

yes, but i don't want to maintain two different options folder.

I think this repo's maintainer is long unresponsive.

Anyway I could not get Blackbox.js or other scripts from this repo even with your patch to run on the newer mpv.
It's also too bad there is no Issues page around.

emm, I thought you were a maintainer, anyway, this is going to be off-topic.

Try add following script into your MPV_CONFIG_DIR/.init.js:

// deprecated directory
mp.module_paths.unshift("~~/scripts/modules.js");

Below to reproduce:

$ mpv --version
mpv 0.33.1-dirty Copyright © 2000-2020 mpv/MPlayer/mplayer2 projects
 built on UNKNOWN
FFmpeg library versions:
   libavutil       56.70.100
   libavcodec      58.134.100
   libavformat     58.76.100
   libswscale      5.9.100
   libavfilter     7.110.100

$ git clone https://github.com/VideoPlayerCode/mpv-tools /tmp/mpv-tools

$ cd /tmp/mpv-tools

$ cat <<EOF > .init.js
// deprecated directory
mp.module_paths.unshift("~~/scripts/modules.js");
EOF

$ cat <<EOF > input.conf
ctrl+b script-binding Blackbox
ctrl+f script-binding Blackbox_Favorites
EOF

$ ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 sample.mp4

$ mpv --config-dir=. sample.mp4
// press "ctrl+b" open Blackbox menu

That got it working for me again thanks! I didn't know ~/scripts/modules.js was deprecated. So what does the unshift do to that path ?
Meanwhile I've merged your commit to my fork. I also put there some small usability tweaks you are welcome to check.

Is it a problem to keep script and script-opts...
Will it give any problem??

And what is the updated fork that i can use??
Dev purposes...

First time trying to get MPV working with Colorbox.
mpv v0.34.1 built from Homebrew on Mac OS 11.6.8

Downloaded your commits for new folder name (script-opts), and following VideoPlayerCode Install-Notes instructions here for renaming Colorbox.js to main.js etc. results in broken functionality of video tools. Following errors in log:

Any ideas please? Thanks.
