A video concept I'd love to eventually do is showing off a bunch of cool tricks / optimizations you can do with the 6502's unofficial opcodes. One day.

NEW VIDEO! The Game Boy Advance e-Reader has had quite the decade so far, I got so much to tell you! ► 8 home brew games reviewed ► 2 developer interviews ► Tons of other discoveries from the community Really proud of this one, hope you like it ☠ youtu.be/0U9fVOmbmjc ☠

Another year of bringing 16-Player Faceball to the world! Thanks to Midwest Gaming Classic for having us and thank YOU to anyone who stopped by and played, or chatted with me, @zarithya.online, and @theunclebob.bsky.social. I’m so grateful to be able to do this kind of stuff with my friends!

This Midwest Gaming Classic was such a blast! It was so great to talk with so many fellow #NES #homebrew devs face-to-face! Too many to people to list, but you know who you are :) #NESdev #indiedev #gamedev #retrogaming

If you're at Midwest Gaming Classic in Milwaukee, Wisconsin. I'm showing off the nearly-finished build of CrossPaint! My homebrew art game for #NES! Come say hi and try it out! #NESdev #homebrew #indiedev #8bit #gamedev

We now have a trailer! I've had a pit in my stomach this past week just thinking of everything that needs to happen, but I'm also so excited to finally have this out to everyone. BioCreeps is an action arcade game for the NES coming very soon. #nes #nesdev #indiedev #biocreeps

It is time! Dizzy Sheep Disaster: EX is now available for purchase for your Nintendo E-Reader! Here's the store link: store.nes.science It contains 30 puzzles to test your reflexes and skills! I'm so excited to share this with the world! #indiedev #homebrew #gba

After a procreative hiatus we are happy to announce that the 6502 Collective is back! We are happy to welcome @supernatetendo.bsky.social and @bitethechili.com to the team, and new things are a-brewing in our labs. In the meantime the back catalog is restocked and ready to ship!

Oh, what could have been... A simple piece of sample art focused around CrossPaint's Tile Copy feature. Some long-time followers may recognize this from my old NESmaker days... #NES #NESdev #homebrew #ファミコン #indiedev #gamedev #8bit #2bpp

Have you ever seen an NES game render 200+ colors on screen? I'm SLOWLY working on the rest of CrossPaint's 16 sample images. This one shows all color emphasis combos + monochrome mode on sprites and BG. Color emphasis on every line is pretty cool :) #NESdev #NEShomebrew #gamedev #indiedev #8bit

In case there's any doubt (and for anyone who knows me, there shouldn't be)... this is my AI policy, specifically as it applies to youtubers, streamers, and other content creators: a🧵, but the tl;dr: *if you want to cover what I've worked on, and plan to use genAI, DON'T.*

Who did it better: - A Quick and Dirty NSF to SAP Conversion from 2026? - A Proper Raster Music Tracker Transcription from 2019? The answer might surprise you :3c Featuring music by @cuttercross.bsky.social once again!

I made an NES emulator called Family Size VM in December and January. To kick off a video series about it, I made a 4-minute explainer video about how an emulator can improve the player's experience. youtu.be/qaCEY67VosU #RetroGaming #Emulation #NESdev

Have you ever fought to make something fit in a PRG bank where it leaves you with literally 0 bytes free? Having a chunk of data overflow by only 5 bytes can motivate you to pull off the most desperate byte-optimizations to make it fit. #NESdev #NEShomebrew #gamedev #indiedev

I've begun working a bit for @brokestudio.bsky.social on a game concept using their 'rainbow' cart, allowing often rumoured/seldom seen mmc5-style 8x8 attributes & tilecount per scene; NES displayable. My process thoughts available on patreon, supporter tier & up. www.patreon.com/posts/148758...

This Christmas, I spent way too much money on upgrading my retro console capture setup... ...to S-Video. 3 Insurrection Industries' Nintendo S-Video cables & a bunch of thick-shielded Monoprice cable upgrades for my splitter box later, I can finally see what good S-Video is meant to look like :)

when i see your name on my screen my stomach flutters and my heart races you make me weak in the knees your memory ricochets through my faces i loved you i can't help it, in my reckoning i miss you come back soon, my rikka-nee

I made a video about off-screen stuff on the NES! www.youtube.com/watch?v=872v...

It's always fun finding a random VRAM update bug that causes full-screen seizure-inducing disco flashes out of nowhere. 😬 [On that note, NEVER forget the terminator byte in your VRAM transfer buffer.] #NESdev #homebrew #gamedev #indiedev

Just so you know... Art directors, Art enjoyers, Art buyers and Artists talk with each other. Nobody wants AI slop, specially when there is real art out there as an alternative. You can totally get blacklisted, not only on the industry, but inside fandoms for defending AI precarization and theft.

I'll never forgive generative a.i Having to ask "is this real?" so often has really done a number on me I miss being able to trust art.

I've finally written enough music & SFX to warrant duplicating my sound driver + SFX data to a 2nd PRG bank, and now importing new audio is 3x more cumbersome. 🥲 #NESdev #NEShomebrew #indiedev

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

I made a series of NES accuracy tests and then ran them on all of Nintendo's official NES emulators. www.youtube.com/watch?v=oYjY...

It's now been a full year since I switched to using desktop Linux, and I'm happy to say I do not miss Windows in the slightest :D

My NES / PC game Perfect Diamond is now available on Steam: store.steampowered.com/app/3871170/... and itch: enjoyance.itch.io/perfect-diam... Comes with a ROM to play on NES emulator or flash cart!

My new NES game Perfect Diamond will be available on Steam and itch.io on August 8th! Comes with a ROM file to play on a real NES via flash cart! Physical NES cartridge release will come a bit later.

I've forgotten how much drawing art assets gives me such intense burnout :(

I find myself enjoying the process of *refining* graphics far more than actually plotting down a rough sketch of basic geometry. And I think the process of figuring out that messy first draft is the real reason why I'm so slow at drawing art assets.

One of the last things I have to work on for CrossPaint involves a LOT of artwork. Unfortunately, drawing is not my strongest suit. I can't say for sure when it'll all be finished, but I want to thank everyone who has followed this project for this long. ❤️ All of this is just a 1-man-crew. #NESdev

📢Big news from Homebrew Factory! You asked for it, and it’s finally here:
 Game Boy and Game Boy Color support is now live! Launch a pre-order campaign, or go straight to production. And we have a brand new Fulfillment by Homebrew Factory service. ➡️ creator.homebrew-factory.com

Oh hey, look what arrived in the mail today :D Thank you again! @brokestudio.bsky.social / @homebrew-factory.com ! #NES #homebrew #8bit #retrogaming

I'm getting pretty close to finishing my new NES puzzle game - Perfect Diamond! Will be available on physical cartridge as well as digital download. #nesdev #gamedev #indiedev

The creators of Myst series (@cyan.com) saved hundreds of video tapes from the making of their iconic adventure game franchose. We helped preserve them. Here's what we found.

The deed is done. 1-based indexing it is! I've also decided to fully scrap the X-SCROLL parameter, as it just caused confusion with the rest of the UI and was too complicated to use in an art workflow. The CHR Fill tool now also disables sprites and emphasis #NESdev #NES #homebrew #ファミコン #indiedev

UI / UX design question for CrossPaint: Should tools with multiple subtools to have their indices start at 0 or 1? Which makes more sense from a general user perspective? If I started indices at 1, it would exactly describe the pen size in pixels.🤔 #NESdev #NES #homebrew #ファミコン #gamedev #indiedev

#gbdk (and #bbstudio) is getting new NES tilemap layouts! By default we use 1-screen layout for simplicity - but this has scrolling artifacts. The NES can do better. 2kB VRAM allows H / V layout to limit artifacts. And cartridges can also provide VRAM for 4-screen layout to remove them completely

Aaaaaand we're live! Check out Mawthorne 2's campaign page and try the demo for yourself! #nes #nesdev #gamedev #kickstarter #indiegame www.kickstarter.com/projects/cra...

Just uploaded NEXXT 3.5 to itch. This quick recording showcases a few of the new features, incl. metatile rosters, cycling, & clonestamp eraser. Cycling through favourites, you won't need to move the mouse back & forth as much. Also works on regular tiles & palettes. frankengraphics.itch.io/nexxt

It turns out if I just preloaded the A X and Y registers before each set of 4 midframe palette writes, I could have cleanly hidden all visual errors within hBlank on both NTSC and PAL🤦‍♂️ [The 1st line of the bottom-left corner of the canvas does not count 🤫] #NESdev #NES #homebrew #ファミコン #gamedev
