A new GameMT handheld called the MTX is reportedly landing in China around September 20, with AliExpress stock following by the end of the month. The claim attached to it is the interesting part. The MTX is said to emulate and play physical Game Boy Advance cartridges.

That is a genuinely rare feature. Almost nothing under $200 reads real carts. The devices that do it well are FPGA hardware like the Analogue Pocket and the ModRetro Chromatic, and they cost a lot more than a GameMT.

There is also a problem, and we are going to lead with it rather than bury it. GameMT announced a handheld with a GBA cartridge slot once already. The device shipped without one.

The Short Version

• Device: GameMT MTX
• Headline claim: plays physical GBA cartridges as well as emulating
• China launch: around September 20, 2026
• AliExpress: end of September 2026
• Chipset, screen, RAM, battery, storage, OS, price: none announced
• Sourcing: a single creator post, no spec sheet, no press release, no coverage anywhere else
• Our read: if the slot is real, it is almost certainly a cartridge reader feeding an emulator, not FPGA hardware

Where This Claim Comes From

We want to be straight about sourcing, because it changes how much weight this deserves.

The MTX surfaced on September 8 in one post from a retro handheld creator. It named the device, gave the two dates, stated the cartridge claim, and attached an eight second video. It did not include a spec sheet, a price, a chipset, or a link to a GameMT product page. The rest of the post was a block of AliExpress discount codes.

None of that makes the claim false. Small creators get early units and early information all the time, and the retro handheld scene runs on exactly this kind of tip. But one post with an affiliate block and no specs is a starting point, not a confirmation. As of today the MTX is not on GameMT's own store, and no outlet that normally covers this brand has written about it.

So treat the dates as a heads-up rather than a schedule.

GameMT Has Promised a Cartridge Slot Before

This is the part that decides how excited to get.

In November 2025, GameMT teased the E3 with a physical Game Boy Advance cartridge slot. It was covered at the time as the brand's first cartridge device, with reporting describing a glass front, a 1:1 display, and a slot that would play GB, GBC and GBA carts alongside emulation.

The device that actually shipped was the E3 Vigor. It arrived in 2026 with a MediaTek MT6592, a Mali-450 MP4, a 3.95 inch 720x720 screen, a 5,000 mAh battery and GameMT's own Android-based OS, at $59.99.

Reviews of the shipped E3 Vigor do not mention a cartridge slot. Neither does GameMT's current store listing for it.

So the honest summary is that GameMT floated a GBA cartridge slot, generated a round of coverage for it, and then released a handheld that appears not to have one. Now the same feature is attached to a new model, on a two week timeline, sourced to a single post.

We would love to be wrong about this. We are also not going to pretend the history is not there.

The Question Nobody Is Asking: How Would It Read the Cart?

Say the slot is real. There are two completely different ways to build it, and the difference matters far more than the slot's existence.

Option one is FPGA. Reconfigurable chips are wired to behave like the original Game Boy Advance hardware. The cartridge is not being read into a file, it is being played, the same way it was on real hardware. Mapper chips work. Save RAM writes back to the cart. The real-time clock in Pokémon Ruby and Sapphire keeps time correctly. This is what the Analogue Pocket, the ModRetro Chromatic and Game Bub do, and it is why they are expensive. Our FPGA versus emulation guide covers why this approach is harder.

Option two is a cartridge reader. The slot dumps the ROM off the cart into memory or onto storage, and an ordinary software emulator runs that file. It is dramatically cheaper. It is also what a budget ARM device running an Android derivative is realistically going to do.

Our read, stated as inference rather than fact: GameMT's entire lineup is budget ARM SoCs running Android skins. The company has never shipped FPGA hardware. Option two is the near certainty here.

That is not a criticism. A cart reader is a legitimately useful thing, and it means the physical cartridges on your shelf are the source of what you play. But it comes with real consequences worth knowing before you buy:

• Saves may not go back to the cart. Most reader implementations keep save data on the device instead of writing to the cartridge's battery-backed SRAM. Your progress lives on the handheld, not in the game.
• Real-time clock games can misbehave. Pokémon Ruby, Sapphire and Emerald use a clock inside the cartridge for berry growth and daily events. An emulator reading a dumped file usually has to fake that.
• GB and GBC support is a separate question. A GBA slot is physically capable of taking Game Boy and Game Boy Color carts, but the reader has to handle those pinouts and mappers too. GameMT's original E3 tease claimed all three. Nothing confirms it for the MTX.
• Link cable features are gone. Trading, multiplayer, and anything else that used the link port is not coming back through a cart reader.
• Dump time. Some readers take a few seconds to pull a cart in before the game starts. Others cache it. Nobody has told us which this is.

If you want a device where the cartridge genuinely runs as a cartridge, that is FPGA territory, and our best FPGA handhelds guide is the right page.

What GameMT Is Actually Good At

Worth some context, because the brand has a mixed reputation and it is not deserved evenly.

GameMT makes budget hardware with unusual ideas. The EX8 is the high point, a $140 Android handheld with a Helio G99, 6GB of RAM and a 4.88 inch 3:2 screen that punched above its price. The EX5 swapped a second analog stick for a physical performance dial, which is a genuinely strange decision that mostly worked. The E5 ModX has a display that detaches, turning the bottom half into a MagSafe Bluetooth controller for your phone.

The pattern is a company that takes swings. Some connect. The E3 Vigor did not, and reviews landed on it being overpriced for what it is.

A cartridge-reading handheld from a company with this track record is exactly the kind of thing that could be a $70 novelty that works fine, or a $70 novelty that does not. There is no way to know from a render.

How It Would Compare

The table makes the positioning clear. If the MTX is cheap and the reader works, it occupies a slot nobody else is in. It would be the only inexpensive way to put a real cartridge into a device and have something happen. That is a real product, even if it is not doing what the Analogue Pocket does.

Should You Wait, or Buy Something Now?

Buy the Analogue Pocket if you want your cartridges played properly. FPGA, accurate hardware behavior, saves that write back to the cart, and a screen that is still the best in the category. At $239 it costs several times what the MTX is likely to, and it is the only one of these you can be certain about.

Buy the GameMT EX8 if you want GameMT hardware that exists and is proven. It is the brand's best device, it emulates well for $140, and nothing about it is speculative. Our EX8 review has the detail.

Wait for the MTX if the idea of a cheap handheld that takes your physical GBA carts appeals and you are comfortable buying an unknown from AliExpress. Late September is close enough that waiting costs you very little.

Look elsewhere if you mainly want to play the GBA library and you do not care about the cartridges themselves. Almost any modern handheld emulates GBA perfectly, and you can back up your own carts to files with a dedicated dumper. Our cartridge backup guide covers how, and best flash carts covers playing those files on original hardware.

Our honest read: the feature is great and the sourcing is thin. A GBA cartridge slot on a budget handheld would be the most interesting thing GameMT has done. It is also the exact thing they announced last year and did not deliver. Watch for the AliExpress listing at the end of September, wait for someone to put a cartridge in one on video, and buy after that.

We will update this page when the MTX appears on a storefront or a spec sheet exists.

Frequently Asked Questions

What is the GameMT MTX?

It is an unannounced GameMT handheld reported to launch in China around September 20, 2026 and reach AliExpress by the end of that month. Its headline feature is a slot that plays physical Game Boy Advance cartridges alongside normal emulation. GameMT has not published specifications or a price.

Does the GameMT MTX really play GBA cartridges?

That is the claim, and it comes from a single creator post rather than GameMT. No specification sheet, storefront listing or press coverage confirms it as of September 9, 2026. GameMT teased a cartridge slot on the E3 in 2025 and the shipped E3 Vigor does not appear to have one, so the claim deserves caution.

Is the MTX an FPGA handheld like the Analogue Pocket?

Almost certainly not. GameMT builds budget ARM devices running Android-based software and has never shipped FPGA hardware. The realistic implementation is a cartridge reader that dumps the ROM and hands it to a software emulator, which is much cheaper and behaves differently from real hardware.

Would my cartridge saves still work?

Probably not the way you expect. Cart readers usually store save data on the handheld rather than writing back to the cartridge's internal save chip. That also means games with a real-time clock, like Pokémon Ruby, Sapphire and Emerald, may not track time correctly.

Can it play Game Boy and Game Boy Color cartridges too?

Unknown. A GBA slot physically accepts GB and GBC carts, but the reader has to support their pinouts and mappers. GameMT's original E3 tease claimed all three formats. Nothing has been said about the MTX specifically.

How much will the GameMT MTX cost?

No price has been announced. For reference, GameMT's current lineup runs from $59.99 for the E3 Vigor and E5 to $139.99 for the EX8, so the MTX would most likely fall inside that range.

When can I buy the GameMT MTX?

The reported timeline is a China launch around September 20, 2026 with AliExpress availability by the end of September. Neither date is confirmed by GameMT, and the company has missed feature promises on a previous device.

What should I buy instead if I want to play real cartridges?

The Analogue Pocket at $239 is the strongest option, using FPGA hardware to play GB, GBC and GBA cartridges accurately with saves written back to the cart. The ModRetro Chromatic at $199 covers GB and GBC only, with no Game Boy Advance support. Both cost considerably more than a GameMT handheld is likely to.
