Ok! Gotta polish these a little bit, but the general vibe for the Redrawn Graphics should be mostly done. #mystuff #smw #romhacking

In homage to dahnamics, who provided SMW Central with many bosses in the early years, including the (infamous) Giant Piranha... These bosses have aged, and the community is long overdue for some better public ones. So to contribute to that, I present the Neo Piranha Plant! 😁 #smw #romhacking

A second frame test. This should be everything I need as far as this guy's graphics go. On to the fun part 👀 #smw #romhacking

Ever wondered how the start of sprite coding goes? I always do the graphics routine first, as it's important to have something to look at. Then I write a frame test, which is a simple snippet that make it cycle through all of its possible visual states. No collision or moves yet. #smw #romhacking

After some deep discussion in the Central (smwc.me/t/132796), I cooked up a little patch that makes the ~controversial~ castle platforms look a little nicer. And it doesn't break the regular ones, either! I'll upload it tomorrow though since it's pretty late 😵 #smw #romhacking

Hey! I've been working on a dynamic sprites system to replace dsx for over a month now. That + private comms left me with no time to post anything here... But anyway, you should go check it out! Here: pk.muncher.se/dsu If you used dsx before, I'm sure you'll like the upgrade :) #smw #romhacking

Inspired by Iceguy's hammer sprite (smwc.me/s/3307), I'm working on a new version that - displays while held - generates a Yoshi earthquake instead of just killing what's directly under it - is not associated to a powerup and can be dropped Soon: buffed variation on extra bit 👀 #smw #romhacking

SPOOKY! A keyhole that only appears depending on a flag, such as the P-switch or ON/OFF. It also fixes the multiple keys bug optionally. This was asked for in the forum, and I couldn't find something like it, so I cooked it up this morning. #smw #romhacking

As my latest commission, a recreation of the classic Orbox recreation from Super Mario :P :P :P. Which is like, the hardest puzzle of all time This version also features angled tiles that instantly bounce the ball in a different direction. That won't get too complicated at all! #smw #romhacking

Wish I coulda been showing more here, but real life, commissions and also moderation have been keeping me busy and tired. But I'll say I'll try to release some (maybe all?) of my shown-but-yet-not-released content this C3, so stay tuned for that! (A hot decade passed since my last C3 thread oh man)

I'm unhappy with the Director's Cut update of Aeron's Golden Cookie Quest, that I released in 2024, because I rushed it to the C3 event, so here I'm working in a Special Edition. First, removed the minimalist status bar, which can get cut in CRT monitors and replaced it with a sprite status bar.

Whenever I get a goal post bar I try to rush summing up the star points before the game does... so I coded a mechanic that lets you do that and rewards you with a life if you get the sum right. Press L or R after any goal post to play! #smw #romhacking

Oh right! I drew the graphics for that boss! They're in essence Icegoom's SMB1 Redrawn Bowser, but bigger and christmas-themed Mario Kart Tour style (it's straight up Bowser's santa costume from that game). #myart #smw #romhacking #bowser #mariokarttour
Look at those smear frames man.

Working on skull rafts that - have configurable size - have configurable speed, including to the left - interact with walls - there can be multiple of independently: one raft won't activate every skull on screen - don't despawn too easily (working on this one) #smw #romhacking

A gimmick I created for one of Saela's latest drops, Karma, applied very graciously. Named by me "Corpse Stepping", it allows you to profane a set number of Mario's corpses for his own filthy platforming purposes. Go check Karma out! Download it here: smwc.me/s/41040 #smw #romhacking
