Man, if it was up to me, every sound bite I would have would be in a separate file in a sound directory. If someone wanted something different, the user could just swap it out. I believe this idea has been brought up before.
This would solve most of the issues.
I had a similar a long time ago with my IJ. Someone on these boards was able to take out the "I HATE YOU AND I HATE THE WATER" quote for me. I had little kids at the time and my wife was complaining about it. Someone literally made a new version of the ROM for me.
Now fast forward to today's pin w/PC's and SSD drives. It would be so simple to allow someone to just override sound bites.
Now the ethical side of me says this probably is a problem. On the other hand, some of these IP owners are over the top with their control of these age old assets.
Oh, IMO without the original licensed songs, TBL really will be taking step backwards. Sad.
My 2 cents....
