Our game Micro Mages is on this! $1 per game is a steal. Many quality NES homebrews in this bundle! It should be a great way to get started and support the #NESdev scene ;) #N8ABundle

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

Bankswitching gone wrong #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...

Coming soon: Micro Mages MAKER! 🧙‍♀️🔨 Steam page: store.steampowered.com/app/3907760/... Wishlist if you'd like to support us and not miss the release <3 Thanks! #NES #NESdev

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

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

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...

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

New Triple Jump Kickstarter update #NESdev www.kickstarter.com/projects/mor...

Update 16: Bonus Game / Final Labels / Limited Edition Certificate / NES KS Shoutout · Triple Jump: A platformer multi-cartridge for the NES

Hi everyone,we received new prints for Triple Jump and have been working hard on the bonus game :)🏄‍♂️ Bonus GameWe made a ton of progress on it and the second round of beta-testing should start soon!...

kickstarter.com

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.

Broke Studio@brokestudio.bsky.social · last yr.

🚨 ANNOUNCEMENT We are thrilled to launch Homebrew Factory, our new platform that allows gamers to purchase homebrew games and helps creators bring their games to life! ➡️ Store: www.homebrew-factory.com ➡️ Factory: creator.homebrew-factory.com

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...

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

‪ - 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

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.

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

Just showing off 😇 #NESdev #TripleJump #NES #homebrew For more info on CHR ROM vs CHR RAM and how games use the two, check out this post: ko-fi.com/post/Bobl--W...

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.

Newest addition to Triple Jump's bonus game: Shops. We thought randomized items could add a lot of replay value, emphasizing different aspects of the gameplay and making each run unique. Balancing ensues. #NESdev
