Added some compression into the mix et voila! Banks $03 and $05 look way less cramped now, that SHOULD be enough space to carry us through the rest of development :) #NESdev

hey that's what I said when starting this project

Morphcat Games @morphcat.bsky.social · 19/03/2026

We haven't posted in a while. Triple Jump is very technical and less visual currently. But here's how the 512KB MMC1 Triple Jump ROM allocates its space. The circled areas are small islands of unused space that we're hoping to tap into. They add up to a whopping 2KB! #NESdev

Turns out Saber Surfers is lacking challenge in the early game so we're reworking the game to favor groups of bullets and geometric patterns. #NESdev More in our latest Triple Jump Kickstarter update: www.kickstarter.com/projects/mor...

It's been 40 years since the NES was released in North America. And a whopping 50 years for the CPU which powered it: the MOS 6502. It launched at $25 in 1975, orders of magnitude cheaper than its competitors and became of the most successful microprocessors of all time. #NESdev

Grunt work, but gotta get these things right. 🤖 Decoupling some moves from their states, making sure they work together gracefully. E.g. the drill (vertical dash) + cocoon (deflects bullets back at the boss) #NESdev

Morphcat Games @morphcat.bsky.social · 24/08/2025

Not right now, I don't think. But sounds like Homebrew Factory/Broke Studio are working on a solution, so hopefully it won't stay like this for too long.

When you finally catch a longstanding bug on an emulator recording. #NESdev 😭 Player is teleported to bottom screen edge and dies instantly when trying to use a gadget with up+B. It happens VERY rarely. Thanks, @betoux.bsky.social !

An ending screen that didn't make it into the game 👽 #NESdev

Morphcat Games @morphcat.bsky.social · 03/07/2025

Oops, missed this one. Is it too late to reply? That's definitely a tough choice when in the midst of development. My half serious take: Always favor speed. Development speed. So everything can fall apart and you'll get to the inevitable rewrite more quickly 😅

Morphcat Games @morphcat.bsky.social · 27/06/2025

Finally getting to do some optimizations :) Improved the engine to handle twice as many objects without slowdown. #NESdev That's gonna come in handy for 4-player mode, which is especially taxing on the CPU...

Morphcat Games @morphcat.bsky.social · 11/06/2025

We added another curse haunting the bottom screen edge in Triple Jump's bonus game. #NESdev He just wants to play. 🦈

Morphcat Games @morphcat.bsky.social · 09/04/2025

Sounds cool, but we're super busy currently. Let's talk about it later this year once our schedule is clear again :)

Morphcat Games @morphcat.bsky.social · 29/03/2025

I've just added the 100th sound effect to this project. #NESdev 20 items, 7 curses. 45k lines of code. 🫠 (Micro Mages was 22k) Sorry for the scope creep delays, I think this has turned into a fine game, now on to more QoL additions and balancing... :) -Julius

Great news for all retro console homebrewers! Broke Studio has been responsible for putting our NES games on physical cartridge. #NESdev Now they're making cartridge production available to ANYONE.

Morphcat Games @morphcat.bsky.social · 26/02/2025

Hello! both cartridge and ROM will be made available

Sorry, but the flicker looks completely wrong :-) The GIF elves strike again

Morphcat Games @morphcat.bsky.social · 26/02/2025

New game relies on a short tutorial, but we're trying to make it as interactive and visual as possible. #NESdev Little surfer animation was done with the help of a lua script that recorded the sprites of a real player doing the move. Seemed like the quickest way given the circumstances.

New Kickstarter update for our NES multi-cartridge Triple Jump! Some print material arrived :) #NESdev www.kickstarter.com/projects/mor...

Morphcat Games @morphcat.bsky.social · 21/12/2024

omg and why don't bosses have the same behavior? being able to bump off of them might make them seem beefier. and the player is actually getting to do something in order to inflict damage? 😱

2100

Morphcat Games @morphcat.bsky.social · 21/12/2024

The result. We wanted the player to not accidentally pop a bubble while they're busy reading. So now, simply touching bubbles isn't enough. You need to use one of your moves. #NESdev

Morphcat Games @morphcat.bsky.social · 21/12/2024

‪ - bubble bump wiggle, unless boost, then bubble slash pop - lighter bubble pop sfx - HUD transition: click, wiggle These TODOs are getting out of hand. #NESdev

Aw, thank you for the kind words!

Faking chromatic aberration on the NES with a combination of screen shake and palette cycling on the sprites. #NESdev #TripleJump Shaders won't be a thing for another 20 years or so.

And maybe didn't give enough info: The reason this works is the NES graphics chip has hardware support to flip sprites vertically and horizontally. I.e., it is FAST. You could rotate sprites programmatically by 90° using CHR RAM, but it would be very very slow.

1110

Morphcat Games @morphcat.bsky.social · 19/11/2024

Looks like we got confused with the flipping directions here: frame 3: 1st sprite flipped vertically frame 4: 2nd sprite flipped horizontally

Morphcat Games @morphcat.bsky.social · 19/11/2024

Did you know that two sprites are enough to create rotating objects on the NES? #NESdev #MicroMages

Experimenting with new items that expand the player's move set. #NESdev #NES #gamedev #TripleJump This particular helicopter one seemed more useful on the drawing board than it turned out to be. But, but, but... it's too much fun to pass up! Might need some tweaking to find its niche.
