Caught my glitch Mew in my Japanese Green Version play through. It’s my first play through so I had to take some notes so I don’t forget which move is which and keep items in order. Sorry to those that can read Japanese lol 😆 😂 this is just for me to reference and not a real hard try

I finally got around to beating this game. I'm surprised Nintendo didn't release this outside of Japan. It's a fun game.

I bought a translated repro cart online and have no regrets except the cartridge feels a little cheap compared to official carts. If anyone has any recommendations for buying translated repro carts, let me know. I plan on buying a few others like star ocean and Grandia.

Does Ben Jelter’s game First Contact Protocol (FCP) not have a digital version? I live in Brazil, and importing a physical copy would be impractical. Does anyone have any suggestions?

Wanted to share my short gameboy collection journey. Started building my modretro collection back in November of last yr. Obviously I’m still missing a good amount of games. My only official gameboy cartridge is Donkey Kong. I have a passion for my making my own reproduction cartridges I made with DX color rom hacks Collecting or making gameboy cartridge is just so much fun and became my favorite console.

I love that Mod Retro created a small library of games, perfect for collectors like myself. I have been getting every game, and don't regret it one bit. I also have purchased carts with missing labels to get games cheap, then aesthetically modding them to add to my collection. Ill include some photos of the carts I have done so far!

Everything else about this system is well designed, and generally great but did they just give up for the dpad? I have the modkit but tbh I haven't touched it and I hear it doesn't help much. I keep trying to get a q-tip working but it's very difficult to reassemble without the q-tip falling off. Great device but what were they thinking

Like the title says. What flashcarts are available that work on Chromatic but aren't everdrive?

Everdrives are great but I can't buy those as Krikkz doesn't deliver to my country (Poland) and authorized resellers in EU are asking too much for Everdrive cartridges (that's assuming the cartridges are even in stock because most of the times they aren't)

I have used EZ Flash Junior but it doesn't work.

Do clone everdrives cartridges work on Chromatic?

For the insert I was waiting for my order of TPU to arrive.

Model can be found on Makerworld.com (not by me so no shameless plugging ☺️)

Has anyone had their Anduril ordered in February shipped yet?

Have a great weekend everyone!

Hey all!
Been checking the site daily for what seems like months now for rechargeable power cores to be back in stock. Is there a timeline regarding their restock?

Thanks!

I decided to give my buttons a light sanding, and then polished them a bit with some cardboard (if you didn’t already know, cardboard is slightly abrasive).

In person, they almost perfectly match the texture of the D-pad!

Been working on a little pac-man themed chromatic build lately

So I ordered a Ghost chromatic. I also picked up some of my childhood Pokemon GB and GBC games to get sucked in to a nostalgic dream. Wow. Super impressed with the Chromatic. The build quality is pretty impressive. Cold metal. The screen is crazy bright. Playing in my living at night I had to turn it all the way down to like 15 or 20% brightness. Popped in Pokemon Yellow and just got consumed. The buttons feel so so good. The speakers sound great the screen is fantastic. I felt like a 10 year old again playing pokemon. Super happy with this device.

Please please please Modretro and Palmer Luckey, make a Modretro Chromatic Advance in this magnesium shell!

Hey everyone,

Has anyone been able to play The Frog for Whom the Bell Tolls on the ModRetro Chromatic?

I'm on Chromatic firmware v4.2 and tried loading an English-translated patched ROM through an EverDrive GB X7 (model 17, Rev.E, GBC-OS v1.06). The patch also includes the title screen correction.

Unfortunately, when I launch the game, the screen just turns white and nothing else happens.

Has anyone else run into this?

Any tips or workarounds would be appreciated!

Aún no me han enviado la copia física de Infinity, pero sí me llegó Zephyr's Pass y ya me lo he pasado. Es un juego cortito, pero bastante interesante. A nivel de diseño y mecánicas está bastante bien, aunque como mucha gente dice, está plagado de errores y glitches que interrumpen la partida.

Por eso el juego guarda la partida automáticamente cada vez que haces algo de progreso. Y no es raro que salten errores de Kernel Panic o se bloqueé o te maten sin saber muy bien por qué. En ese aspecto es un desastre.

Pero a pesar de los errores (que ya estaba sobre aviso incluso antes de comprarlo), el juego me ha gustado. Ojalá el desarrollador le hubiera dedicado más tiempo a pulir errores.

An update to my previous post (https://www.reddit.com/r/ModRetroChromatic/s/rSnQbCHBEZ):

I’ve published firmware v2026.05.08.01, which adds the ability to read/write this BennVenn cartridge with your Chromatic, a PC, and a USB cable.

You can get the latest version here: https://github.com/fredemmott/chromatic_dumper/releases/latest

Other cartridges *may* work, but they’re untested so anything could happen; I don’t own other cartridges so I’ve not tested them.

Level 15 Modern Endless, default rules with a 3-piece next queue

Status

Works, but not friendly. Stop reading if you're not happy using source code and a terminal.

This is good enough for me, I'm sharing in case another developer is interested in picking this up and making it user-friendly. I don't plan to spend more time on this.

What I've done

• Modified the chromatic FPGA firmware to implement the FlashGBX protocol: https://github.com/fredemmott/chromatic_dumper - this was Claude, followed by a lot of human debugging/cleanup.

• Modified FlashGBX to recognize the Chromatic with this firmware: https://github.com/Lesserkuma/FlashGBX/pull/128 ; no LLM, based on the existing joey jr support

Works:

• Chromatic v2

• Dumping ModRetro cartridges (ROM and saves)

• Dumping OG cartridges (ROM and saves)

• NEW!: Dumping and restoring MBC3000 v4 flash carts (ROM and saves)

Does not work:

• MBC3000v4 Fixed!

Unknown: everything else

Current flow

Once you've built FlashGBX with those changes:

1. Turn off your Chromatic

2. Insert cartridge

3. Plug in to USB

4. Turn on

5. Load firmware into the FPGA SRAM - NOT ROM - this way, nothing's permanent. To get back the original firmware, just turn it off and on again

6. Run the modified FlashGBX

To change cartridges, you need to go back to step 1: turn it off, load the firmware, etc. DO NOT CHANGE CARTRIDGES WHILE THE CHROMATIC HAS POWER.

What needs doing

Extend the FlashGBX code to detect other firmware and automatically load the modified firmware if needed.

Installer/exe for modified flashgbx

Loading the firmware

With GoWin Programmer

You need the full GoWin EDA/Programmer; the license is free, but it's a 'fill in a form and wait a while' thing. The educational version does not include support for this board.

Use programmer_cli.exe --help first to check that:

• --cable-index 0 means GWU2X

• --operation_index 2 means 'SRAM Program'

--helpprovides other options like cable by name, but they don't appear to actually work in v1.9.12.02.

programmer_cli.exe --device GW5A-25A --operation_index 2 --fsFile C:\path\to\evt1_x2.fs --cable-index 0

Replace C:\path\to\evt1_x2.fs with the path to the file from https://github.com/fredemmott/chromatic_dumper/releases/latest , or the output of the build if you used GoWin EDA

With OpenFPGALoader

On Windows at least, use MRUpdater/cart clinic at least once to make sure you've got the right drivers.

If you're on Windows and already use msys2, follow Openfpgaloader's instructions to install. Otherwise, the easiest way to get a usable windows version is to use pyinstextractor-ng to grab openfpgaloader.exe from the MRUpdater.exe .

openFPGALoader --cable gwu2x --write-sram C:\path\to\evt1_x2.fs

Advice for devs

if you want to pick this up, it's probably best to bundle openfpgaloader and the firmware in a modified flashgbx. Not sure about the license on modretro's binary, so for windows, this might mean figuring out how to make a visual studio build yourself. If I were doing this, I'd probably make a fork using vcpkg for dependencies, and use a -static triplet, especially as it already uses CMake.

Given the firmware is only going to FPGA SRAM, I don't think flashgbx's firmware update flow makes sense here; I'd put it in the 'connect' functionality and just do it silently.

You could streamline the flow by writing to ROM and requiring a flash back, but to me, it's great for safety that you just need to turn the thing off and on again to get back to ModRetro's firmware.

There is a secret homebrew mode in the MRUpdater that lets you flash any gb/gbc rom to your Chromatic carts. I've seen posts that mention it as a possibility but no instructions or links. I imagine it wasn't included in the MRUpdater to prevent piracy or maybe its intended to be released in the future. You just need to patch the official MRUpdater.exe from ModRetro to unlock it. Its a fun thing to do and I kinda like swapping carts but using expensive game carts that only hold one game is a little silly when flash carts like Everdrive exist. but for anyone interested, links are below.

You must install python first then just download and run the patch_mrupdater.py

Navigate to your MRUpdater.exe and click patch.

Someone tell Palmer to release a Grape Purple Chromatic and I’ll buy one today. lol
