Apparently this fell into a few spam boxes :( If anyone on the list got bitten by this reach out, I'll make sure you get a copy!

Get ready! Dizzy Sheep Disaster: EX launches for the Nintendo E-Reader TOMORROW at 12 noon US eastern time! Check here to get one of the first copies! (ps: those who signed up for the mailing list, make sure you’ve checked it recently!) #indiegame #gba #gamedev

Have you seen how e-reader cards are scanned? I made a quick video in case anyone isn't familiar or needs a refresher! #gba #gamedev #homebrew

Dizzy Sheep Disaster: EX was originally written for a week long game jam in 2017! The graphics and gameplay have since been overhauled, but all of the mechanics are still there 4 more days until game release! #gba #retrogame

Pixel Pup's title screen is getting there. No longer being placeholder content makes the game feel more real. Pixel Pup is an upcoming #picross game for the #GameBoyAdvance being made by myself and @objetdiscret.itch.io #screenshotsaturday #indiedev #gamedev #gba

Dizzy Sheep Disaster: EX was originally written for a week long game jam in 2017? It has seen many changes and improvements since then. 4 more days until game release! #gba #retrogame

Did you know? Dizzy Sheep Disaster: EX for the Nintendo E-Reader only has 16kb of program code space- that’s half of Super Mario Bros! The game has to store some of its level data as graphics just to fit! #gba #nesdev #homebrew

My goal is to get the next alpha of Pixel Pup out next week. The plan is for this to be the final alpha, as it will be the entire game minus bugs, some polish, and 2 player mode. Then, once 2 player mode is done, we'll release a beta, and from there the final release shouldn't be much longer.

Reminder we have ONE WEEK left until the launch of Dizzy Sheep Disaster: EX! The store link will be shared on April 14th at noon us/eastern. Follow me here to be among the first to get it! #gba #indiegame #homebrew

I had a function implemented wrong, and its wrongness just happened to hide a really nasty bug, and hide it for weeks! Ah software development, never a dull moment.

The first 50 packs of Dizzy Sheep Disaster: EX are ready to go! Just over one week to launch day! Follow me here to be one of the first to get your copy! #homebrew #gamedev

Today we launch the e-Reader e-Reader!

Dizzy Sheep Disaster is a new e-Reader game coming on the 14th! It was made by @sarahlynne.bsky.social, @mteegfx.com and @humanthomas.bsky.social #indiedev #gba #nes

Thank you @retrodotcards.com for this fantastic unboxing video!

I’ve been teasing it for a bit, but here’s the official word: Dizzy Sheep Disaster: Ex is going on sale on April 14th! I’ll have around 100 copies for sale through an online store to start. Stay tuned to get your copy of the game for your Nintendo e-reader and the web! #gamedev #homebrew

It’s coming!

Please watch and share my new pilot called Deathahedron! It took me a year to make it, it's made almost entirely with little models that I made and shot in my backyard. I had to make the costumes, hand animate the effects, it's a labor of love! V----CLICK HERE----V www.youtube.com/watch?v=-FNC...

Hmm, what’s this? 🤔

Pixel Pup, an upcoming picross game for the #GameBoyAdvance, will keep track of your hint number completions automatically. That will make puzzles with many 1's, like this one, less tedious and more fun. #ScreenshotSaturday #indiedev #gamedev

Did you know? The e-reader has a NES emulator on it, but due to GBA limitations you have to carefully design your art with duplicate lines to make it look crisp! Sprites are actually 6x8 instead of 8x8 More detail in this blog post: igwgames.com/blog/2025/06... #homebrew #nesdev

ps: Stay tuned! A release may be coming very soon!

Gateway2Drillbit covered my Series One cards in their 2025 ReviewMo video. Here they reviewed many games and had their 2025 year end awards. This video is an hour long yet I ended up watching the whole thing! So if you're looking for more game content, check em out www.youtube.com/watch?v=y1hz...

And the same function can be used to blend backgrounds too.

And what do you know, half transparent sprites on the e-Reader!

I was searching to see if anyone figured out a way to make the Tingle Tuner work in the Switch 2/NSO version of Wind Waker. Found this helpful article. "How to use the Tingle Tuner on Switch 2. The Tingle Tuner cannot be used on Switch 2." Uh... Thanks.

I’m starting to make final cards for Dizzy Sheep Disaster: EX! Part of the process has been printing and testing full sheets of cards. This is done by cutting them into numbered strips, then running them through the e-reader to test the dotcodes #retrogame #gamedev

I just had an idea for the next Terminator movie that's a dystopian future with AI terminating people from their jobs...

Here's some behind-the-scenes art from Pixel Pup, the #GBA #nonogram game that I'm making with @retrodotcards.com. 🧩🎮 This background has little caves and castles now, but at this point, it was just a mountain landscape. 😄 #PixelPup #PixelArt #IndieDev #GameDev #homebrew

Oh for sure. But I dunno, there's just something about weird things like this. It's fun and I can't really explain why.

And major props to @djtatsujin.bsky.social who brought a spare TV!

We figured out the monitor disaster and got people playing the game.

Finally cracked the code on getting individual GBA sprites to alpha blend. It seems like most gba dev sites gloss over this a bit. It wasn't until I finally found the magic paragraph I needed in gbatek that it clicked. I'm going to write a blog post on this so I don't forget.

You can try the first early release of Pixel Pup for your #gba here. Check the release notes on this page to see all the known problems. www.retrodotcards.com/pixel-pup/re... #screenshotsaturday #indiedev #nonograms

My cell phone plan is so old, it has minutes.

@objetdiscret.itch.io's Taiyaki Fabulous puzzle pack is really coming to life in Pixel Pup, a nonogram/picross game for the #GameBoyAdvance #screenshotsaturday #indiedev #gba #wip

Dizzy Sheep Disaster: EX is coming along! I think I’ve found a reasonable way to print the final cards! Just some minor alignment issues to solve now. If all goes well expect to see these at an upcoming retro gaming con!

Here is a little demo and some explanation/pondering on what happened with Pixel Pup on the e-reader. www.youtube.com/watch?v=QnrS...

I wrote a (long) blog post detailing how this pixel drawing works on the GBA www.mattgreer.dev/blog/gba-dev... #gamedev #indiedev #gba

Actually it should just be removed from TCRF straight up, it's not an unused card effect.

Thank you very much. The post has been deleted. I really appreciate your research. This information should probably also be added to TCRF for future reference.

It's not a very known fact but Super Mario Advance 4 does have a menu that you can freely access with Select where you can save your playthrough of a level, whether in the SMB3 levels or World-e.

Enabled simply by replaying a replay of a level with Luigi. Simply through normal means, no hacks. It was never intended to be used as a card effect, it just happens to share the same space as the rest of actual card effects.

Very interesting! So, how do you think the effect would have been activated, if you have any guesses at all? I would like to be as informative as possible in my follow-up.

I've just checked by recording a replay through the game (after playing a level in World-e as Luigi, press Select to save a replay and play them), and the same "effect" gets set. So it's unrelated to Cards, just happens to share the same variable as the rest of the card effects to be enabled or not.

Oh, this is new information to me; I was under the impression that it was nearly certain. Please let me know if you find anything that suggests it was not intended to be a card effect, and I will amend the post with that information! Thank you very much for looking into this!

Turns out I didn't have to, I just used the in-game replay system, and I was right. That "effect" gets set anytime you replay a demo with Luigi.

I need to make my own Luigi Demo Card to make sure
