A genuinely cool new device recently appeared on the market: ChisLink. It brings a fresh approach to Game Boy Advance flash cartridges. ChisLink connects to a computer over Wi-Fi, letting you write games directly to the device's memory card from a browser. Then you can reflash ChisFlash on the fly, right from the console, with no cables and no PC connection.
I recently spoke with an EZ-Flash developer and got a few interesting updates worth sharing.
1. The OMEGA line is being discontinued
Because of chip shortages, the EZ-Flash team has decided to end production of the OMEGA-series cartridges. Their place in the lineup is now taken by the EZ-Flash Air. The currently active models are therefore the EZ-Flash Air and EZ-Flash Definitive Edition.
2. Why the Air has no save states
I specifically asked why the EZ-Flash Air does not include instant saves, or save states. The developers explained that because of the device's architecture — in particular, the lack of RAM — implementing the feature would introduce noticeable delays.
In simple terms, saving or loading a state would take several seconds even in the best case, making save states unpleasant to use. The team therefore decided to leave the feature out of the EZ-Flash Air entirely.
3. New products
The team is not currently working on any completely new devices. The main focus is improving and optimizing the EZ-Flash Air. Once that work is complete, however, they may return to the EZ-Flash Junior and EZ-Flash Parallel.
So EZ-Flash Air is becoming the main option for anyone looking for an affordable and reliable GBA flash cartridge, while the OMEGA heads into retirement.
A large package of flash cartridges from China arrived recently. Huge thanks to our honorary Chinese friend Ruslan for helping out!
1. Two complete EZ-Flash 1 sets.
One of them, in the white box, is the very first EZ-Flash sold before Borden sold his company to the EZ-Team. The other, in the black box, is the redesign released afterward.
Update: Borden sold EZ-Flash immediately after the black-box version was released. So both box designs were actually his work.
2. A mountain of Chinese flash cartridges with assorted cables.
Nothing especially exciting, but still a decent addition to the collection.
3. Two SuperCards.
I mainly bought them because of the purple CF version. I already had one, but it was dead. Guess what? This one does not work either :) The search continues.
4. A PassWe 3 with a very worn cover.
I bought it purely because it is rare — these things are almost impossible to find.
5. ChisFlash — a new rewritable flash cartridge with a reader.
At first glance, it looks like a more affordable version of the EZ-Flash Definitive Edition.
The new cartridge has a larger NOR capacity (960 Mbit), but no RAM at all. That means games can no longer be launched directly — they have to be written to NOR first, which is not exactly a fast process.
Rumor has it that EZ-Flash is having trouble sourcing chips, which has temporarily halted production of the Definitive Edition.
On July 1, 2025, the Mig-Switch team released firmware update Mig-Switch 1.2.1.
What's new in version 1.2.1:
Behavior more closely matching that of an original game card;
Improved support for the first hardware revision (Mig-Switch V1);
Expanded compatibility with trimmed ROM files.
The developers gave special thanks to TotalJustice for helping improve the firmware.
To make the device behave as closely as possible to an original cartridge, the team carried out detailed comparisons between Mig-Switch and genuine game cards using a dedicated test rig across a variety of scenarios. The result: no behavioral differences were found. According to the developers, Mig-Switch with firmware 1.2.1 is now practically indistinguishable from a genuine game card.
A major wave of bans has started over the use of Mig-Switch on Nintendo Switch 2. It turns out Nintendo has significantly expanded the telemetry collected by the console. For example, it analyzes access speeds to memory sectors. This data can be used to determine whether a game is running from an original cartridge or a flash cartridge.
This information comes from hexkyz, a well-known reverse engineer and security researcher specializing in Nintendo consoles. His analyses are frequently a reliable source of information about how Nintendo systems work internally and how their security operates.
Lately, various “experts” have been posting videos supposedly showing Switch 2 games running or being dumped, hoping to generate hype or even make some money.
Don't fall for it: most of this material is completely fake.
The latest example is a video by someone called deadkernel, supposedly demonstrating a custom firmware called BlueNX-launcher v0.8.1-alpha.
📹 The video was filmed on an original Switch 1, not a Switch 2.
❌ It uses firmware HOS 18.1.0, which does not exist on Switch 2.
🔢 The serial number does not match the Switch 2 format, which starts with HAE1003XXXXXX.
🧠 It shows 4 GB of RAM, while Switch 2 has 12 GB.
🌀 BlueNX-launcher v0.8.1-alpha is vaporware: software that is claimed to exist but that nobody has actually seen or can use.
📌 Bottom line
Be skeptical of “leaks” on social media and shady websites.
🎮 At the moment, there is no real CFW for Switch 2.
The developers of Mig-Switch (also known as Mig-Flash) have released patch version 1.2, which for the first time allows games from the original Nintendo Switch to run on the new Switch 2.
“My Switch 2 test has been banned, after using the mig switch with perfectly legal dumps of my own cartridges, so it would seem that Nintendo can detect something.”
He also added that similar reports have started appearing on Reddit:
Then again, knowing how greedy the developers are, it is entirely possible that instead of a firmware update they will release a “new” cartridge specifically for Switch 2 — just to make us buy it all over again.
