I also put FF in my JM, and the results were lackluster. They are amazing speakers, but the JM PCM hardware just doesn't sound very good. I have pre-ordered a Pinsound unit, and I'm pretty sure this will make the game sound amazing. I'm also working on a remix/retheme of all JM's music, since the original music is lousy IMHO.

I am swapping the music out with more ambient/techno-ish music that just "fits" better. I have several samples gathered together, but still one or two need some work.

It's actually a fair amount of work, since you have to find and trim to the the "magic" 30s-2min of a song, or set something up to loop without being noticeable. I'd love to compose my own, but time just doesn't permit.

Additionally, I am redoing several of the callouts, since some of them are /terrible/, "if they go technical, go crude", ugh. I'm going to replace them (and all of the impersonations) with samples from the actual film.

Also trying to a add a little more fanfare. The extra ball callout for instance is so flat--it should be screaming from the rooftops that you got an extra ball, like MM, TOTAN, or CV.

Will definitely share with the community!

I'll make a post with a video similar to the one I did for my Tron music replacement:

You betcha.
