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)

What else is cool about this?
- Automatic detection of pole height
- Configurable tape speed
- Calculation of score based on relative height of the bar. I wonder if a frame perfect hit at the top scores a 1-up? πŸ‘€

Welp, overhauling my SMW Kris sprites from like 2 years back with my current skillset, just wanted to share the progress so far - left ones are the newer/updated ones (WIP, expect updates!)

Just dropped two goal march-themed patches:

- Pictured, a fix for the time to score tallying on level end yielding glitchy score values if the time is between 400-999: smwc.me/s/41475
- The bonus stars sum game I showed off before: smwc.me/s/41476

Enjoy! #smw #romhacking

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!

The way I played a part in designing the preliminary sketches for the Bowser Throne Room πŸŽ„!! I love seeing sketches come to life in its full glory ✨✨

TDW / StrikeForcer, thank you for commissioning me!

Drew some running animations for my playable Mario gang yesterday, heavily inspired by Mario Wonder.

Giving the frames a bounce touch was honestly kind of fun.

Look at those smear frames man.

Look at those smear frames man.

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).

HNY! I've been away for the holidays, but just before Christmas I was able to deliver this nifty boss for StrikeForcer's @romhackraces.com level: Winter Bowser!

Featuring two phases, including riding a sled with multiple attacks!

Finished animating my Yoshi's House equivalent for my SMW hack. I'm a bit shocked I was able to economize so much of this thing given the limitations I was working with...

After some trials and errors I finally managed to add a short intro for the world bosses I'll be using in my SMW hack.

Bowser Jr. was quite literally the guinea pig for this.

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)

SPOILER WARNING! Final boss created for the other one of Saela's latest drops, Replica, where Mario sets off in an adventure to face his biggest enemy...

If you think I've been a little too quiet with bosses recently, well, I just gotta be 🫒

SMBX project a little bit on hold. I've been having other cool ideas left and right that I wanna do. At least I've done a few of the cooler ones by now :P
