Hello everyone! In a little more than a hour (8:00 PM PT / 11:00 PM ET), I will be showcasing a custom Boom Boom I made for a future hack of mine. It's not a long showcase, so be sure to catch it when it premieres! If not, well hope you enjoy the boss regardless. :)

The beauty that is birth... #smw #romhacking

HAPPY 40TH BIRTHDAY SUPER MARIO #smw #supermarioworld #romhacking LINK IN REPLIES

Umm... hi?

working on the visuals (Hoot sprites by the incredible @izzi8bit.bsky.social ) upon starting a run, there's a ~25% chance of him appearing, landing on the progress board at night; he won't leave during the day, instead sleeping through it he's only here to hang out, so he doesn't do anything else

Hi, I just set up a Patreon! The options to support me are there, but I also wanna use it to ramble about my ASM works. A post about the baby Reznors is already up - if you're into that, go check me out: www.patreon.com/c/koopsterth... And since this will be pinned: pk.muncher.se/commissions/

Preparing another release! 👀 #smw #romhacking #smbx

These dudes are adorable! Might actually make them a miniboss tbh. #romhacking #smw #mystuff

A concept from SMBX I've always liked. Line guides and solid sprites are two challenges for sure, but I've always wanted to make these happen in #smw! #romhacking

If you look closely, the Renzors' positions have a one frame delay related to the platform. It'll happen as well when Mario steps on it. If this issue bothers you and you've already grabbed the sprites, redownload - it was a little annoying but I just fixed those.

Ever wondered how Bowsette would look like if she behaved like Mario 3 Bowser but in Super Mario World? Well, so did I. Which is why I made this graphics pack. #myart #romhacking #supermario #bowsette

Since making the rotating blocks was pretty fun, I'm considering making something platform-related next. And colorful.

They're almost wrapped up for release! I was just figuring out a way to add a setting to easily turn them into actual bosses while still letting them be enemies. Setting a digit in the extra byte of any of the platforms should now enable level end trigger! #smw #romhacking

Baby Reznors! They should be bug-free now. It was easier to make dedicated platforms to them, also adding the ability to knock them from below. #smw #romhacking

Forgot to post about this but CroNo has been putting in a ton of work on an awesome beginner kaizo collab with a ton of great creators. Looking forward to people checking it out later this year! (sorry in advance for another wonky layer 2 level xD) www.youtube.com/watch?v=V05r...

It started as a simple walking enemy, but I decided to implement a platform association that's making me go nuts and is still very buggy. Still, here's a very polished and totally not bug-avoiding recording of a little guy that, who knows, might get released soon 👀 #smw #romhacking

Heya everyone! You might've seen some small teasers before, but, I've officially released the OST for my newest WIP hack on Youtube! There are also a lot more stuff over on the C3 thread, including new level showcases and new additions. Check it out: smwc.me/t/130552 www.youtube.com/playlist?lis...

Everyone keeps complaining about Fishin' Boo cause his flame teleports when he turns, so I stopped him from turning to make him easier. #smw #romhacking

I don’t think it’s rta viable anymore.

I don’t think it’s hard enough.

Love the way these guys groove #smw #romhacking

Was this level always like this? #smw #romhacking (Also I guess be careful with spinjumping on high bouncing enemies)

Believe it or not, I do stuff that's NOT music! For those who don't know, on SMWC's last Summer C3 event, I showed off a tiny demo of my new hack, "More Super Mario World". Since then, there has been some changes to the demo levels, and this is one of them! Now it has some new music and effects.

One of my favorite creations for sure, "Terraria" water, granted me a pretty nifty placement in the Mad ASM Scientist contest back then. "Terraria" because I thought draining mechanics would be way too hard :P #smw #romhacking

Big Boo but he mastered occult arts this time #smw #romhacking

Hi! I'd like to announce I'm kicking off ASM commissions. From simpler stuff, to bosses, to general assistance with your hack, I'm eager to help you out! For further details: pk.muncher.se/commissions/ My portfolio is on that page, but I try to keep this account posted on my stuff too 🙂

Touhou hours (hard) #smw #romhacking Actually made it on the first try during recording, talk about a gamer

Touhou hours (lite) #smw #romhacking

Third and last of the koopalings I've done so far, pipemaster Wendy. I've done a bit of balancing since I first designed her, but she is meant to be pretty difficult to deal with. Only 4 to go, I wonder what I can come up with! #smw #romhacking

Have you seen xMANGRAVYx's latest drop? If not, you should! Castlemania II is a short and sweet hack I was happy to contribute with coding-wise, in smaller and slightly bigger things. You'll see my work by the end of stage 2 when you meet Denise, a menacing fire-throwing fish! #smw #romhacking

Another bunbun 4 segment in the works :) I had originally designed a much longer segment, but I think this one will succeed as a simpler rendition that also uses the idea better! Just need to get stuff lined up at the end :)

After an intense bullet level, you'd think a goal post awaits you. But I made the hack, so... #smw #romhacking

That was Roy* :P Anyway, ~here's~ Morton, who puts on a tougher battle than his brother. Fun fact, those two are the same sprite with a different extra bit! #smw #romhacking

Apparently those guys are from some new Mario game. And for you kaizo people, Hoppycat gates when? #smw #romhacking

A non-mode 7 rendition of Morton I created a few years ago. Simple, but I think it's pretty fun My goal is to make my own spin at each of the bosses for my personal hack and eventually release them #smw

In the next days I'll [try to] bring my old stuff over to this account. My Twitter account had some fine engagement but I don't wanna go back there...

The fun's OVER #smw

I dunno if there's even a demand for this - probably not, considering it's been 25 years and this hasn't ever been done to my knowledge - but I made a little patch that lets you have a lot more turning blocks at once. Sorry zip fans #smw

Updated my custom OW paths patch to allow to make Mario go behind "foreground" tiles at will, which is useful for paths crossing bridges and such. While I've used this trick in the past, it was implemented in a deranged way, to which this is a much more user friendly alternative. smwc.me/s/38846

Slight progress on this also

A bit more touch ups not much else added from last time but i thought i should post it here either way #smw

I've been spending my time studying and learning more about pixel art, using it to Great Effect in my smw hack by redrawing the stuff I drew months ago from the ground up (foreground only atm)

youtu.be/zaCmaNIAVnA See you soon. (Premiering 1:13 PM PT today.) I am covering the title screen an intro in this preview. Collab with @evilguy0613.bsky.social, @wakanamizuho.bsky.social, @nopecontest.bsky.social and @koopster.bsky.social
