I tried replacing the English version of the brsar with the Japanese version, and it ends up messing up more than just the announcer's voice. So I guess that doesnt work. And I havent been able to find any BRSAR re-packers, only unpackers. But if there is one, then it may be easier to replace...
I feel like school, back when I was actually in school, was more entertaining though, because of how much I get to interact with people, hang out with friends, and other stuff like that. All I get to talk to at work is my boring coworkers lol
