I'm not sure how often this happens. Enough that it's mentioned specifically in some of the tournament rules.
The first ball had 2, maybe 3 extra balls (guitar, mystery, guitar again). It was over a half hour.
I think the game is pretty bad ass as it sits, I doubt this happens that often. Rather than bother trying to code a new digit, wouldn't it be easier to make everything score less if you were to do it?
When most people think about an update to this game they are wanting better audio samples. And less Welcome to the Jungle. I have a feeling new audio samples infringes on copyright stuff.
I saw a newly designed sound board that would allow this but it would be an insane amount of work, if it worked. And the board was expensive. I considered tackling it myself, I have audio editing experience and all the gear. I could easily re record any of the filler music, voice calls would be the toughest part.
If I could hae a GnR with great sound and the ability to change out songs without too much work it may never leave.
