Recently got my hands on the homebrew calendar from @scrobins.bsky.social and it’s so cool to see all the games in it! A certain sheep may also be featured! (Yes it’s an e-reader game, but there’s a NES game under the hood. It counts!)

It’s here! The 2026 NES Homebrew Calendar is out: featuring gorgeous cover art by @supernatetendo.bsky.social , 12 homebrew games, and fun homebrew holidays, this is what you want on your wall! Available in a U.S./Canada edition, and EU/rest of the World edition. www.etsy.com/shop/TheScro...

Finally building a better intro/instructions screen for Dizzy Sheep Disaster: Ex! It used to be dense text. That text now lives on the e-reader cards! Demo next week? #gamedev #homebrew

A new blog post that goes over how Pixel Pup's puzzle pack cards work. www.mattgreer.dev/blog/hacking...

Y'all, I know two hours is a big time commitment, but this panel I arranged and hosted last month is one of the most important things I've ever done for video game history. The launch of the NES is a crazier story than most people realize, and my guests were extremely generous with their memories.

The bees have a scarier cousin, be afraid of hornets! They see you, and they want your fuzzy blood. You have to move quickly to stay safe. Dizzy Sheep Disaster: EX is coming soon for your e-reader and phone! #gamedev #homebrew #screenshotsaturday

Be careful of the bees! Bees follow the huge magnets chasing our sheep in Dizzy Sheep Disaster: EX. Time your moves carefully to avoid being stung! Coming soon to your nintendo e-reader and phone! #gamedev #indiedev #homebrew

Will be at portland retro game expo all weekend! If you see me, say hi! I’ll also have the latest Dizzy Sheep prototype with me, if that’s your sorta thing

Surprise! I’ll be at Portland Retro Gaming Expo this weekend with the latest prototype build of Dizzy Sheep Disaster: Ex No booth but feel free to stop me if you see me around! #prge #prge2025 #retrogaming

Dizzy Sheep Disaster features a number of scary enemies that our magnetic sheep must avoid! Ticks are small, but will quickly end her journey. Be careful! #screenshotsaturday #gamedev

I’ve been working on packaging for Dizzy Sheep Disaster lately, here’s a prototype of the e-reader booster pack design! The label art is a mockup pending final design from @mteegfx.com, who I know is gonna make it look amazing! #screenshotsaturday #gamedev

I'm super stoked to finally reveal these card designs, y'all. Everything from the text, illustration, and layout are the culmination of something I've been wanting to do for a long, hot minute; and @sarahlynne.bsky.social's been a total blast to work with on it.

The amazing @mteegfx.com has been working on card designs for Dizzy Sheep Disaster: EX for the Nintendo E-Reader and I’m loving the results! We’re getting close to ready! #homebrew #gamedev

Not everyone has an e-reader, so I’ve been working on a web-based version of Dizzy Sheep Disaster you can play from a QR code or a link. It’s coming together well! #screenshotsaturday

Been quietly working on Dizzy Sheep Disaster lately. Here’s a winter stage showcasing the reverse direction button for #screenshotsaturday!

I put together a list of Awesome e-Reader Folks! bsky.app/profile/theu... If I'm missing someone, lemme know! @retrodotcards.com @sarahlynne.bsky.social @vaporwario.bsky.social @caitsith2.bsky.social @blisy.net @hitsave.org

I'm still hard at work on my e-reader game, with hopes to release it by the end of this year! Lately the focus has been the web-based emulator. I want to make sure people without an e-reader still get a really fun experience #homebrew #gamedev

I've been a bit quiet but I'm still hard at work on Dizzy Sheep Disaster: EX! I recently wrote up a guide on how to make an e-reader game from a NES game. Give it a look! igwgames.com/blog/2025/06... #nesdev #homebrew

New blog post, how I made Exo Attack for the #nintendo E-Reader #gamedev #indiedev mattgreer.dev/blog/making-...

The real deal! Here's the actual cards, just picked them up from the printer.

I just got the proof in from the printer. The cards look and scan great! The E-Snake cards came out way too dark though, so I will be tweaking those. It's so on!

Bit of a nerdier #screenshotsaturday, I've been bumping up against space limits for Dizzy Sheep Disaster for a while now, so I borrowed a trick from Super Mario Bros. I put most of my level data into extra graphics space, saving me over a kilobyte of space for code! #gamedev #homebrew

First "alpha" print run was a success! I've got a lot more testing to do, and a few minor tweaks to make here and there. e-Snake is not present due to challenges I am having printing it on my home printer. But no worries, it will be in the release. This silly idea is getting really real 😲

Easing back into work on Dizzy Sheep Disaster by finally animating the reverse direction button. Going to try to do the same with the end-of-level switch next! #gamedev #retrodev #screenshotsaturday

I'm finally home and (mostly) rested after Midwest Gaming Classic. It was a really wonderful time! I loved meeting and chatting with so many like-minded gamers. Thanks to everyone who stopped by to play Dizzy Sheep Disaster or say hi!

Dizzy Sheep Disaster is at #MidwestGamingClassic for a few more hours! I’ll pick a winner for the prototype giveaway around 1pm local time, so stop by before then to sign up!

As a heads up, my e-reader cards are not business cards! If you took card 4/4 while you were at my booth by mistake, please return it! Unfortunately I may no longer be able to give away a full/working set at the event.

Super excited for this to be exhibited. Making the art for it has been super fun, and @humanthomas.bsky.social's music brings *so* much life to it.

I’ll be set up all day in the VideoGameSage room at #MidwestGamingClassic! Come play Dizzy Sheep Disaster: Ex! Or play with Retro Puzzle Maker We’re in room 102D!

I’ll be flying out to #MidwestGamingClassic early tomorrow, and I’ll have prototype cards for my game in hand! I’m going to give away a set of prototype cards towards the end of the event, ask about it if you stop by!

I was finally able to make some tunes for a video game featuring SHEEP. AND it runs on an E-reader!

I was recently able to add music from @humanthomas.bsky.social to Dizzy Sheep Disaster, and it really brings the game to life! Come try it out at Midwest Gaming Classic later this week! #gamedev #indiedev

@mteegfx.com recently animated the main sheep sprite for Dizzy Sheep Disaster and I can't get over how much it adds to the game! ITS SO CUTE! #gamedev #indiedev

Fun news, I'll be at #MidwestGamingClassic in a few weeks! I'm bringing a prototype of Dizzy Sheep Disaster, my puzzle game for the E-Reader, to the Homebrew area I'll also have a setup for Retro Puzzle Maker, if you'd like to check that out!

I got to experience this with an early version of my e-reader game the other day, and this is SUCH a good feeling. I found some things to change, but I also found things I absolutely won't!

I'm trying to post about my projects here more often - I've been working on a new game for the Nintendo e-reader! It's a full rework of Dizzy Sheep Disaster, featuring graphics from the ever-talented @mteegfx.com! Here's some WIP screenshots #gamedev #indiedev

Slowly but surely, the cards are getting there.

It's been hard to make progress due to time and energy being leeched away by the actions of the new US administration, but I did put together a gameplay video of a recent build of Even Goblins Fall In Love. youtu.be/teEH0yzjShk #indienes #gamedev #homebrew #retrogame #nes #nesdev #indieretro

Another blog post about printing e-reader cards. This time mostly talking about how the test run on the digital press turned out (it turned out well!) www.mattgreer.dev/blog/printin...

Thank you to anyone who got a copy of Squishy the Turtle from me at magfest! Your energy and excitement was super encouraging! Stay tuned for a more full-fledged e-reader game coming from me in the future!
