I am currently trying to use this project for dumping offsets, and it says this:

You can terminate a task with Ctrl+C.

Optional arguments:
-h, --help shows help message and exits

-i, --resolve-imports rebuild the import table from scratch
-w, --wait wait for the process to start
--ignore-sections a list of section names to skip [nargs: 0 or more] [default: {}]

Failed to open process. I am sure the filename is "Robloxplayerbeta.exe"

The process needs to be running before you can dump it.

[Ketnlas]

The process was running.

To dump the image, in the directory vulkan.exe resides in, run the following command:

.\vulkan.exe -p RobloxPlayerBeta.exe

The -p argument is case-sensitive.
