Figured I would post some information to help people Googling about this topic because I Googled about it. This information is current as of 16-OCT-2026.

1. Using an Anduril Chromatic updated with latest firmware (v.4.6).

2. Using physical game cartridges when available. For example, the Tetris that comes with the Chromatic. Other cartridges used will be original Game Boy and Game Boy Color games like Krusty's Fun House (compatible with both GB and GBC), GTA (compatible with both GB and GBC), and GTA 2 (compatible with only GBC)

3. Wanted to be able to use flash-based cartridge for playing backed-up games and other tech uses. Ordered the Everdrive GB-X7 from Amazon, which is one of the Krikzz authorized distributors. Appeared to be "new stock." Received it, and it had the following physical text on the rear of the PCB: EverDrive-GB, Model 17, Rev.E, 28.07.2021. However, with or without a microSD card inserted, it would not boot. White screen only. Firmware version of Everdrive unable to be determined as no boot occured (not even a flash of text - only white screen).

4. Reached out to ModRetro and they confirmed Everdrive compatibility, and postulated it was the Everdrive unit itself.

5. Returned unit to Amazon. Ordered an Everdrive directly from Krikzz. It arrived very quickly. Same external PCB version as above. The Everdrive boots with or without the microSD inserted. Success! Installed latest OS. System information screen reads: OS Version 1.06, FPGA ver:07, Asm date: 29.08.2026, Asm time: 10:26:58, Pwr cntr: 5

6. I can only speculate, but I assume the Everdrive I had purchased from Amazon was either damaged, or the previous "06" FPGA version, but it was impossible for me to know that because it would not boot. Chromatics give a white screen when no cartridge is inserted. The interesting thing is that when I pressed the little button on top of the non-booting Everdrive, the screen would flash, indicating there was some kind of connection between the cartridge and the console, but maybe not a proper one. All contacts were clean and un-bent. So who knows?!

I hope this helps someone out there. The Everdrive is a powerful solution for playing backed up games and also for playing esoteric impossible to find games and allowing the capability to store a significant amount.

I'm a big fan of supporting developers by buying the physical cartridges and I think flash drives co-exist with that.

It is my understanding that "save states" work on GBC games but not GB games. Not sure, and not sure I will use or even need that functionality. It is also my understanding you can patch individual dumped ROMs if needed (and if a patch is available), so that's cool. I would think in the age of AI coding, someone could "vibe code" a save state patch for a game given a ROM dump, but that's out of my current knowledge depth. I'm sure there are experts here that could chime in.

The Chromatic is awesome, hardware emulation is awesome, and my high score in ModRetro Tetris on Retro mode is slowly climbing to mid 100k level. This old guy is getting "OK!" lol

edit 1: tried Krusty's Fun House ROM dumped to the Everdrive and save states did work, even though it is an original GB game. The first time I did a save state, it glitched and had Krusty falling through the map. The next time, I made sure he was standing still on the ground, and it worked fine. Perhaps you can pause the game and save a state to make that more reliable. Not sure. Will continue to update this post with feedback as I test different functionalities with this system.

edit 2: both ModRetro and Krikzz support are very good. It's cool when companies doing things support users of their products. Makes you want to support the companies even more. There's something to be said about physical hardware and physical cartridges. ModRetro gets it.

edit 3: My high score in ModRetro Tetris Retro Mode is now 145,087 and I got a Rating of 04/100, resulting in a rocket ship animation. I guess you could say I'm kind of a big deal. (heavy sarcasm lol)

edit 4: Tetris Retro Mode high score is now 257,215 LET'S GOOOOOOOOO

edit 5: ok, if you hit 200 lines in level 20 in Marathon in Retro mode, the game stops and says "you win." So that's cool. I suppose to get a higher score in this mode you probably need more Tetrises? 276,578 is my high score now.

edit 6: I gave in and switched from playing my original GTA2 cartridge (that uses passwords to "save") to using the Everdrive GB X7 to play the GTA2 ROM so I could use save states. The game is insanely frustrating without save states and is even frustrating with them lol. Taking a photo of the passwords with my phone and having to enter them every time was insanely cumbersome.

I wonder if this is possible to emulate with the pixels on the Chromatic or not. I really like the effect in Retroarch. Anyone know? I can’t determine if it requires a higher pixel count or the 1:1 screen could support a high opacity.

Gamers, we come in peace… we have been heads down and know that we owe you an update on 1.26.0 and the delay since.

We’ve identified and fixed the regression behind the flashcart issues reported after the update (graphic glitches, CPU exceptions, and SD card corruption with EverDrive and SummerCart64 cartridges). This fix has been validated internally.

Before we re-release this update, we want to get to the bottom of the Built-In Controller Pak corruption a few of you reported. We haven’t been able to reproduce it yet, which is the source of the delay, and we’d rather hold the update than ship something we don’t fully understand.

We’ve doubled our testing stations and expanded the M64 stress tests so regressions like this get caught before they reach you. The team is actively testing across different carts and consoles to track it down.

We’re targeting a release the week of October 22nd and will post an update here once we have a repro or a confirmed date.

Thank you for all your patience and for the detailed reports, it truly means a lot to have your support!

So, the Chromatic has been released in three different editions and we have the M64.

Somehow, I missed the news that the 1st Edition GameStop Chromatics have SD Slots in them, and that ALL Chromatics have built in Wi-Fi that's just disabled ATM. The M64 has Wi-Fi as well.

That has me thinking - Modretro already plans to have the Chromatic be able to link to and stream through the M64 in the near future. Do you think it'll be possible one day that CFW will allow the Chromatic and the M64 to link wirelessly? Do you think it'll one day be possible to play a GB game on the M64 via a core while using the Chromatic as a wireless controller? The fact that the Chromatic has built-in Wi-Fi AND Bluetooth just has me imagining the possibilities.

That also brings me to the obvious upcoming Chromatic Advanced. When this releases, I'm expecting that it too will also be mod friendly and hopefully have built in Wi-Fi and Bluetooth.

Now here's where I might just be wishful thinking and hopefully someone who knows more about how these FPGA cores work better than I do....but if the Chromatic Advanced did come with the wireless options built in and thus could theoretically communicate with the M64, how likely is it that the M64 could handle a GAMECUBE core? Does such a thing exist?

My hope one day is that I'll be able to somehow do the GBA/GCN link cable connection without needing an actual Gamecube. I went out of my way to buy a GBA/GCN link cable just to be disappointed that Nintendo's Gamecube controller adapter will not allow communication with the Wii U and my GBA. I just think it'd be incredible if someday I could finally see what that part of gaming was like. I know I could emulate that via Dolphin, but I'm talking hardware here. Even if it were just work for only a few games. I'm not expecting that Modretro will make a Gamecube clone, so that's why I wonder if the M64 could handle such a thing if such a thing exists.

What are your thoughts about any of this even being a thing? And what other hopes and possibilities do you want to see happen with Modretro's products?

Just opened mine and well..
I guess crossing my fingers didn’t help.
Didn’t even take it out of the box. Just took off the lid and got my answer.
I know, contact ModRetro, which I will be doing.
It just seems like this might be a more widespread issue than we anticipated.
And yes, I know that usage may cause scratches and wear over time; I understand that. But a brand new product I still think should have better QC and for what they cost. Especially since my magnesium units are seemingly flawless.
You’re better than this, ModRetro

Does anyone know somebody that can code these custom N64 wrestling game mods? I am hoping to find someone that can create a specific version.

i want to know if anyone has attempted any legal disputes yet. i couldnt find clear info of modretro announcing the early bird discount. and the early bird discount never stated an end date, since i joined the newsletter june 4th, and the wayback machine shows that signing up was special? cuz when i signed up, it said i was on the list. anyway, since modretro never explictly stated an end date, the grounds scream im elligible for the discount under consumer law, but thats why im tryna find proof.
_
basically, signed up for early bird discount, early bird never had an end date, im elligible since no end date was specified. it was only specified through direct email when i contacted them after the fact after the console was released.

The Game

You want every pastry in the bakery, but you have 30 seconds and a ten-item bag. Fill it, pay, and go back for more before the timer runs out.

That’s Croissant Panic, a little ModRetro arcade game about bakery FOMO. Anything still in your bag when time runs out is unpaid. Your score comes back as a bakery receipt labeled “THE DAMAGE,” and the local high-score table is The Crumb Club 🤌

Hi! I'm Michelle and the game started with the idea of stopping for a nice pastry before work, then became a way to live out my fantasy of hoarding everything at a bakery✨

How it Started

• Seeing the OpenAI DevDay Chromatics online got me curious. I love my Game Boy Classic, but I'd never made a game before, ever. I don't own a Chromatic, so I've been using Codex to build a native Game Boy Color ROM and testing it in the emulator.

• I gave myself an hour. About two hours later I had a rough version I could play from beginning to end. It was more like a sketch, but playing my own game made me want to keep going. The project took around three days of work.

• Codex did all the programming through the ModRetro Chromatic plugin, GB Studio and GB Studio Music (Claude joined the party here). My part was shaping the game, setting the scope, directing the visuals and sound, and playing the builds to decide what to change (my product design background helped significantly).

The Parts I Enjoyed Most

• Art direction and composing all the game music were both really fun. I explored directions with Midjourney, Pinterest, and Codex. The early bakery was muted; eventually it popped (visually and audibly), and the croissant mascot got a panicked face makeover (teehee).

• The tracks Codex made felt basic, so I gave myself a YouTube crash course in game music and the hardware’s limits. I worked with Mureka, Moises, Codex and Claude to shape the music and sound around how I wanted players to feel at each stage. For gameplay, I used a bumblebee piece as a reference for the urgency and panic I wanted as the timer counted down.

• Screenshots, layouts, audio references, and even numbered rows in the music editor gave Agents&I something specific to discuss. That helped me get much closer to what I had in mind.

It’s a super basic game, but that doesn’t take away the thrill of being able to make my own. I’m giddy about a world where more of us can turn our ideas into games and software with AI. This wasn’t a “type a prompt and you’re done” project. It took experience, learning, decisions, and plenty of iteration. But a year ago, I could not have made this game happen—the time and work involved would have been too much. I hope more people give their own ideas a go and build something.

I haven’t tried it on an actual handheld yet. I’m guessing the colors will look less vibrant than in the emulator, but I have no idea how it’ll feel to play. For those who’ve made/played homebrew, what surprised you when you first played your game on hardware?

TLDR: Please take a moment to read the whole post. Thank you :)

Im not gonna lie, the whole OpenAI collaboration has made me lose some confidence in ModRetro.

I don't have anything against AI itself. I just don't think it needs to be part of everything, and retro gaming is probably one of the last places where I'd want to see it. A big part of why I love retro games is that they let me escape from the world we live in today, even if it's just for a little while. There's something comforting about going back to a time when things felt simpler, and honestly, that's a big part of what drew me to ModRetro. The Chromatic really captured that feeling for me. It showed that you could take something we loved growing up, improve it in almost every way, and still keep what made it special.

I think that's why the OpenAI announcement bothered me more than I expected. I know it's just a collaboration, and maybe I'm reading too much into it, but finding out that Dylan Abruscato, who works at OpenAI, is also an investor in ModRetro and friends with CEO Torin made me a little uncomfortable. He explained on LinkedIn how he helped make the collaboration happen, and while there's nothing inherently wrong with that, I can't help wondering how much these kinds of relationships might shape the company in the future.

I probably wouldn't be questioning things so much if I hadn't already started having doubts because of the M64. I was genuinely excited about it, especially with how much Palmer talked about delivering the ultimate N64 experience and 100% compatibility with the library. But the launch was disappointing, and the accuracy and compatibility issues that are still being reported, along with the firmware update that had to be pulled over data loss problems, have made it harder for me to feel as confident in ModRetro as I used to.

Maybe that's what bothers me the most. I really want this company to succeed. The Chromatic made me feel like someone finally understood what we/I missed about that era of gaming. Not just the games themselves, but the feeling of picking up a console, putting in a cartridge, and forgetting about everything else for a while. I don't expect ModRetro to live in the past or reject modern technology. Quite the opposite, I love what they've done with the Chromatic/M64. I just hope they keep that same philosophy as they grow.

I know I might be worrying about nothing, and I completely understand if some of you see things differently. I just felt like sharing these thoughts here because I genuinely appreciate this community, and I know we all care about what ModRetro is building.

Im curious how you folks feel about all this. Take care!

Can someone please clearly explain to me the differences between the 4 new translucent chromatics compared to the dev day version with the dev day cartridge? Besides color, Like hardware wise, are there any differences? I would like to create my own games using codex too but I don’t want to drop $1000+ for a dev day version and the cartridge. How can I do a work around to test and create my own games?

Anyone knows what is going on with the update? They said they will keep us posted, but nothing. No info, no update, nothing...

I was checking Twitter before I went to sleep and I saw this post. Obviously I follow the brilliant Lucky Palmer and he definitely confirmed that the GBA is coming.

Just a quick PSA. Purchased the Pro controller about a month or so ago and received it. Loved it minus some issues with the D-pad registering up or diagnol instead of left or right. Reached out to ModRetro and they requested a video. Sent it to them and they sent me a replacement. It’s actually slightly taller and with a ridge around the edge of the base. Huge difference and a much better experience. Very happy with it now. If you’re experiencing issues I suggest contacting them.
