I've read how this "mod" make the game that much cooler. I've also read that unless you have a perfectly playing game it can cause a lot of issues and that it really doesn't change game play much. My JD is playing well but I always have some credit dot errors that don't seem to effect gameplay. Errors are left upper and lower flipper EOS errors and I get a trough error but the game still plays as it should. Would I be foolish to add this mod?
