I'm trying to get a good (if not best) music plug in for my psp, currently using MP3Player Plugin v2.2 but its got some problems. It won't work when I try to use it while playing ps1 games or sega games (I'm aware of those only) Second, the music freezes on and off when i do certain things while playing online like switch weapons (only happens when i do it the first time)

I'm aware that this isn't the latest version but its the only version i could find. If anyone could provide me a link to the latest version or a much better music plugin then i'd be very thankful.

As for game category plugins, I checked on bubbletune's website and he only has released v1.3 out. So what are these other versions I've seen like 1.5 for example, is it made by the same bubbletune's or some other person?
