How can I bulk rename files by removing text after the first set of parentheses?

You can definitely do this in batch scripting if you're used to it. Just make sure to test your script with a few files before running it on all of them to prevent any mishaps!

Here's a PowerShell command that might do the trick! You would navigate to your folder and run this:
```powershell
Get-ChildItem *.rom -File | Rename-Item -NewName {($_.BaseName -replace '([^)]+)).*','$1') + $_.Extension}
``` This effectively renames your files by trimming the text after the first parentheses. Just remember to test it out first!

If you have a large number of files, consider using parallel processing to speed things up. Depending on how many files you're working with, it can make a difference!

If you're comfortable with regex, you can use it in PowerShell to target the strings. A simple script could replace everything after the first set of parentheses while keeping the extension. Just iterate through your files with a for loop and apply the changes.”

You might want to check out PowerToys' PowerRename feature, which can handle bulk renaming pretty well! Just set it up to match the parentheses and it could save you a lot of time.
