Thats interesting. I personally am completely sick of the ruby music because I've played so many Rom hack. Im in love with jupiter version mainly because of the music =)
What i will probably do is leave some of the original music in the game and change some. That's IF i can figure out how. I havent tried yet, ill save that for the very end.
As far as progress goes i have 7 gyms completed. So this hack is getting fairly close to done. I also changed the tiles a bit to make it look different.
And finally, a special thanks once again to Mavy42. Mavy is going to make a couple of the gym leader sprites for me
