I made an updated version (although pretty similar still) and uploaded it to soundcloud in case anyone is interested.

i like how its isnt just black knife in a different soundfont.. you made an effort to make it sound like it comes from earthbound. i think you did a good job. :)

•Susie took mortal damage!
•Ralsei took mortal damage!
•Kris kneeled in silence.

Oh my god, the knight looks so much like an actual late game enemy in earthbound

I like how it starts with a fake-out intro with the Otherworldly Foe
and so far the Knight does seem to be one
Great job on this remix, actually capturing the essence of Earthbound's weird style!

I also love how it just sounds so rushy with the tempo changes, representing the panic you'd have on this fight

0:38 wow this started off goofy and got really intense, kinda like Pokey means business!

by roughly 1:09 the song goes from this weird, uncanny, distorted version of the Knight's theme to finally finding it's footing,  like the Knight it'self needed to adapt to the new system and way things are.

*The Roaring Knight tried PSI Starstorm Ω...
*PSI Starstorm Ω dealt major damage to Kris.
*The Shadow mantle made PSI Starstorm Ω disappear!
*667 HP of mortal damage to Ralsei!
*Kris kneeled in silence...
*Ralsei got hurt and collapsed...

The Knight's first attack is literally Starstorm α, and the final attack is literally Starstorm Ω.
You can't convince me to think otherwise.

you couldn't comprehend the true form of the roaring knight's attack!

this isnt my fault i swear

•Kris coughed
•Kris caught a cold!

As far as adaptations of Black Knife to the styles of other games goes- this is on par with that Sonic Adventure 2 cover.
This isn't just a "remix" or a "soundfont cover" thing- you didn't just slap a different soundfont's notes onto a midi. This sounds like it BELONGS in Earthbound. This sounds exactly how I would imagine if there was an optional fakeout boss you're SUPPOSED to lose against. Something that you're nearly guaranteed to lose to, probably multiple times, but is by no means impossible, and not through luck, but through proper planning.

You don't beat the knight by panicking. You defeat the knight through sound strategy and focus. Even as those numbers tick down, you HAVE to stay focused, and the sheer overwhelming pressure of at least one of your HP boxes going red EVERY turn may be intimidating, but you CAN do this.

0:37 What the beat sounds like in the morning
1:10 what it sounded like at 11pm

Edit: It's a joke lads, art is art

IT’S NOT JUST THE SOUNDFONT THAT MAKES IT SOUND LIKE A GENERIC SNES COVER THIS DOES EARTHBOUND COVERS JUSTICE

1:32 Insane justice done to my favorite part of Black Knife, thank you

i love how the song becomes softer at the end... it's like how dess is still somewhere in there

i love the absolute cacophony at 1:58, it really sells the feeling of intense pressure you get from fighting the knight

Let's be real, running into an enemy like this in Earthbound would be freaking terrifying.
