It doesn't sound bad at all, but basically everything save for the main melody is redone, in part or in full.
My question is kinda useless now, though... I'm porting Legendary Illusion ~ Infinite Being, and I kinda just realized that my midi is an official remix from the ZUN himself... so it's technically just as legit as the one in Mystic Square.
I'm still trying to borrow from the original version though, since some parts are simpler and the midi has way too many tracks playing at once.
So yeah, sorry for asking a dumb question, I was just unsure if it was even worth it to keep working on the port. I'm not exactly satisfied with how it sounds so far, and I can see the struggles ahead to try and fit all these instruments onto 8 channels, so I didn't want to do all that and still risk rejection because it's basically nothing like the original.
Thanks for your replies regardless, I'll probably try to tackle this one again if I get better. I should be focusing on other things for my hack anyway.
