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:

An expansion to Sumo Brother's flames that
- only ends when ground ends
- has configurable spread speed and vanish speed
- there can be twice as many of as in vanilla (20 versus 10)
Just gotta add interactions and pack it with a Sumo Bro, and the fun may be had :)

Now truly accurate to #smbx, Toothy is now able to eat blocks! Just a little more testing before this one is out too 👀 #smw #romhacking

mirror temple b-side! really happy with how this turned out. the combo of yoshi and theo is really cool with all the item juggling, dismounts, and item spits/eats. might be the hardest level yet? looking forward to the RTA attempts and making the next level!

Alright, done that - while GPS custom block code will be entirely ignored, my cluster sprite now gives a framework to program custom behaviors on bullet contact.
Useful for on/off blocks, brick blocks and so on. The most basic examples will be included!

I got down to the point where I realised I simply can't make the cluster bullets interact with custom blocks, lol
As compensation, I added the option to make specified map16 tiles to shatter on contact with them
I wonder if there's a good way to add more common behaviors, like on/off blocks...

A quickie - a patch that allows spawning monty moles in their walking state by placing sprite 12 (originally unused). #smw #romhacking

Latest commission out of the oven - keys that trigger the destruction of a chain of blocks, based on a similar entity in Super Meat Boy.
Allows crossing chains, speeding up and slowing down the destruction and even blocks that turn into other blocks! #smw #romhacking

Just finished a writeup on my Patreon about my SMBX assets to SMW project. This one mostly talks about what I have done so far. In a follow-up post, I will talk about what I still want to do! Go give it a read if you're up for some ASM rambling.

With the Billy Gun from #smbx, you're invincible!
In my #smw version,
- bullets are cluster sprites, so up to 20 can be on screen, allowing for INSANE shooting rates (see reply)
- bullets still interact with the foreground, including blocks and slopes (as well as fireballs do, at least)

You wouldn't have guessed but the hardest part about making a resource is creating a sample level to show it off in video

It's Toothy! A little fellow straight from #smbx that slaughters all who encounter its maw. Features
- consecutive scoring which resets when it's dropped
- full carriable sprite behavior, like hitting blocks and staying in Yoshi's mouth

After some discussion on this topic, we were able to figure out how to make boo blocks actually stay still as they spawn. This way, their disguise ACTUALLY works - a bit crazy that we've been designing levels with them where this isn't the case for 25 years! #smw #romhacking

My entry "DINO POP!" for the 48hour SMW contest. The theme was to combine 2 levels from SMW. I combined Soda Lake and Chocolate Island 1. This was very fun to make and I'm happy with how it turned out!

- support custom code for specific sprites when hatching

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. :)
