A glance at my liked tracks and you'll understand my unhealthy obsession over Bonetrousle.
I had to make another cover, this time using the SM64 soundfont.
It came out poopy but whatever, i suck at mixing lol.
Made in Musescore 3.

Bonetrousle 64

Made this a track to tell people i have a musescore account where i post mostly impossible piano covers of random stuff. If you care enough to check it out it would mean a lot to me, even if you don't like it :>

Nyeh Heh Heh/Bonetrousle + Trailer Version (Musescore 3 Recreation) [read description]

Nyeh Heh Heh arrangement based on the Bonetrousle arrangement i made some years ago, which i ALSO updated and retouched while making this. Expect me to post a slightly updated Bonetrousle (re)arrangement as well soon.

Made in Musescore 3 with SGM sf2.

UNDERTALE | 016 - Nyeh Heh Heh! (Arrangement)

And there we go.
I decided to take my 2 year old Bonetrousle cover, adding some instruments and other things overall. The structure is almost the same as the old one, but with modification, extensions,  and hopefully a better mix lmfao.
Made in Musescore 3 with the SGM sf2 and the chiptune sf2.
Shoutout to Roi (https://soundcloud.com/end-mii-106734392) who always appreciated my Bonetrousle covers, i'm glad i can share this weird obsession over a single Undertale track with someone without feeling weird about it lol

UNDERTALE | 024 - Bonetrousle (2023 Arrangement Rework)

I took a piano arrangement of sans i made a month ago and reworked it on Musescore 3 to make a full arrangement like i did with Nyeh Heh Heh and Bonetrousle.
I first wanted to just do a recreation of it but i got carried away.

UNDERTALE I 059 - Spider Dance (Arrangement)

So, the original project for my Bonetrousle arrangement actually had the trailer part towards the end, but i scrapped it. This is not really complete but i tried to polish it as much as i could.

[Bonus] UNDERTALE | Bonetrousle Trailer Version (Arrangement)

fun fact this was supposed to be out for halloween but music and art block struck me down so badly i basically stopped doing anything till now lol
 anyways this is a reacreation and an arrangement just like the sans cover i did.

Made in Musescore 3 with SGM and Earthbound soundfonts.

UNDERTALE | 038 - Spooktune (Recreation/Arrangement)

to justify the fact this is like the fifth time i cover this song, i wanted to test with the Proteus 2 and chiptune soundfonts more and trying to envision what a ''remastered'' Undertale soundtrack could sound like.
(Note: this isn't part of my personal Undertale Rearrangements project, therefore won't be put in the playlist)

Software used: Musescore 3

Had the wip to this sitting in my pc for months and decided to finish it. Wanted to make it in time for undertale 9th anniversary but oh well, happy (late) birthday to the game that changed my life lol

UNDERTALE | 036 - Dummy! (Arrangement)

This is my favourite Underfell take and it's a shame it hasn't been continued. I love the designs and the music is just so good, everything feels edgy but in a funny way and that keeps the sillyness of the canon undertale characters.

Ok so i have never played this game nor do i know this character very well, but GOD i love the music in Sparkle's trailer and i like the character too (i love clinically unwell women).

Super Mario 64 | Snow Mountain (Arrangement)

I have never finished this game or went that far honestly, the game music is still engraved in my mind tho. Maybe i should give it another go eventually.

The Legend of Zelda: Ocarina of Time - Song of Storms (Arrangement)

i deleted twitter

My friend violilith got me into Persona 3 very recently after she finished playing the remake.. i watched the 4 movies and now going through the ps2 ver of the game, and i'm digging it!! The music is SO good and i might do some other songs from it in the future.
For this arrangement, she helped me with the drums and the bassline in the second section of the song. While she doesn't make games covers, i strongly suggest to check her music anyways! www.youtube.com/@violilith

UNDERTALE | 024 - Bonetrousle (2025 Arrangement)

not my proudest cover and the mixing is prolly dogshit but i tried to approach a different style with this one since i've discovered how insanely hard hitting pokemon black and white drums are. also this is the first cover i made after finishing Persona 3 FES for the first time and i may or may not have cried like a bitch at the end lmao

DELTARUNE: Chapter 2 | NOW'S YOUR CHANCE TO BE A (Arrangement/Cover)

this took too much time and it's so poorly mixed it hurts but i just wanted to post it so badly. Tried to finish it before Chapter 3 and 4 released but i just ran in so many problems and the file kept having audio clips whenever i tried to export it. Hope it's still somewhat enjoyable lol
