I’m pretty sure make mkv doesn’t do this so this might be off topic however is there a way to change or remove region coding to region 1 or region free .iso/backup ? With or without software even outside mkv?
I found some links online but wasn’t sure how trustworthy since they all require downloads
Region change
Re: Region change
On BluRays region lock is purely software related. So if you use e.g. VLC and set VLC to the specified region, your BluRay should play.
