Quick How to Use / Troubleshooting

For Windows

1. Download and Install Microsoft Visual C++ Redistributable Packages (x86 and x64) for Visual Studio 2015 – https://www.microsoft.com/en-us/download/details.aspx?id=53840

2. Extract the software zip file (found in Downloads) and plug in GBxCart RW. Windows will look for the CH340G driver. If the device isn’t automatically detected, you will need to open up Device manager, find the “USB 2.0 Serial” device and update the driver using the files in the Drivers folder.

3. Open up the GUI from Interface_ProgramsGBxCart_RW_vx.x_GUI_InterfaceGBxCart_RW_vx.x.exe. You can move this folder anywhere you like.

4. Unplug GBxCart RW (only if you have the v1.2 board and below)

5. Select the correct voltage for your cartridge using the switch (GB/GBC uses 5V while GBA uses 3.3V), insert your cartridge and then plug in GBxCart RW. If using the v1.3 board, it’s all software controlled, just select the mode correctly before opening the port.

4. Click the Connect button and the little USB icon should turn from grey to green.

5. You should now click “Read Cart Info” to read some basic information from the cartridge. You can now backup the ROM,  backup your save game to your PC and restore your save game to the cartridge.

For Linux/Mac

You may need to install this CH340G driver – https://github.com/adrianmihalko/ch340g-ch34g-ch34x-mac-os-x-driver

1. Extract the software zip file (found in Downloads) and plug in GBxCart RW.

2. Open a terminal window and change directory to the Console Interface (Interface_ProgramsGBxCart_RW_vx.x_Console_Interface).

3. You will need to compile the application by typing in “sudo make”.

4. You can then run the application by typing in “sudo ./gbxcart_rw_console_v1.20” for example.

If it has trouble connecting to the serial port, try running “ls /dev” and see if you can find a device similar to tty.chusbserial630.

If you find one similar, you will need to edit the rs232/rs232.c file, just replace one of the existing entries in the variable below: char *comports[RS232_PORTNR]={“/dev/ttyS0″,”/dev/ttyS1″,”/dev/ttyS2”,

And then re-compile.

Please send us a quick email about the port you find so we can provide an official update.

Troubleshooting

If no lights are showing when plugging in the device or the device isn’t being detected

  • Try using a different USB cable (preferably a non-phone type USB cable). This Startech cable is know to work.
  • Try using a non-USB 3.0 port if you are using one.
  • Try to unplug all other USB devices except your keyboard and mouse.
  • Uninstall the device from Device Manager and choose to delete the driver files as well, then try to re-install the drivers and ensure the device shows as CH340.

If it’s timing out when performing any of the functions:

  • Try using a different USB cable (preferably a non-phone type USB cable).
  • Check to see that you have no other software which monitors COM ports such as the Arduino IDE running in the background.
  • Try using the Console Interface

If you’ve tried all the above steps but are still experiencing issues, please contact us at support@insidegadgets.com

FAQ

My game isn’t detected properly
Sometimes you may have to move the cartridge a little to the left/right on the cartridge slot as it’s not a perfect fit. You should unplug GBxCart, move the cart and then plug GBxCart back in. If that doesn’t help, you should open the cartridge and clean the cartridge pins either with isopropyl alcohol or the pencil eraser method.

How do I know if my flash cart is re-writable?
You will need to open the cartridge up and check to see if the flash chip identification markings matches or is close to the ones listed on our product page or the manual.

Carts that were developed more than 20 years ago won’t work as most of them are EPROM based and require a specialised programmer that can supply 12V.

Carts developed 10-15+ years ago such as the GB Smart 32M, Bung, EMS, etc aren’t supported at this time but may be in the future. Unfortunately these cartridges are hard to find as well as the information on them and older flashers that support them aren’t open source. Some cartridges may require reverse engineering which can take hours so it’s not a priority for us.

Our product is open source, so if you know how to add support for these cartridges or any others, you can easily modify the console flasher interface to add the additional cart there.

My clone cart isn’t flashing properly
– You may have to clean the cartridge contacts or re-seat the cartridge.
– You should try reading the cart info to see if you receive a game title that you expect from the cart, if not, then sometimes wiggling the cartridge left or right a little bit can help.
– If the clone cart flash chip isn’t on the list, you could try selecting other flash chips to see if they work
– You can running the Flash ID programs to see if your cart returns a flash ID. You will see it read the ROM and if any of the next lines have different data then we we know the flash chip is responding.

While clone carts are supported, we can’t guarantee that clone carts will work, some may have slight differences in their assembly.

My GB/GBC clone flash cart won’t play some games
Some of these clone carts don’t support the MBC1 mapper properly, so some MBC1 games may work but others might not. You can manually patch the game to change it to be MBC5. Here is a listing of games and their MBC types: https://ladecadence.net/trastero/listado%20juegos%20gameboy.html

My GB/GBC clone flash cart won’t save
Please check if your cart has a battery installed. If not, you will need to install one.

My GBA clone flash cart won’t save
Please check if your cart has SRAM save type and that the game you are running also uses SRAM. If yes to both, the cart requires a battery to save. There may or may not be a place to install a battery.

If your game saves to an EEPROM or Flash then it won’t work on any of these carts unless you patch it to use SRAM, the GBATA program seems to work well for this as reported by some users. If the cart you have doesn’t have a spot for a battery, then you will need to patch that game to save back to the flash. Check what save type your game uses here.

Nowadays it appears that most GBA clone carts don’t have any place for a battery and they patch the games to save back into the main flash memory. In terms of finding a 32MB SRAM battery backed cart – we have good success with this GBA 32MB SRAM battery backed cart.

Which flash carts do you recommend?
For Gameboy carts – we would have to recommend our Gameboy flash carts firstly which are available at our shop.

In terms of clone carts, for the Gameboy, we have had good success with the Pokemon Crystal carts which usually contain a 2MB flash chip and battery backed SRAM.

For the Gameboy Advance – we now have 2 GBA carts available: a GBA 32MB, 1Mbit Flash Save, Flash cart (no RTC) which works with all the Pokemon games or a 512Kbit Flash Save cart for certain other games.

For clone carts we have had good success with this 32MB SRAM Battery backed cart but you need to note that not all games use SRAM for their saves, for example, Pokemon GBA games use a flash chip for saves.

If you are looking for Pokemon GBA clone cart which you wish to re-flash, there is none we can recommend at this time because most clone carts have the Pokemon game patched to save the save file back to the main flash chip where the game is stored. This means you would have to patch your games to do this too which as far as I know, is a manual process.

The EZ-Flash Omega might be a solution but it’s not as cheap as clone carts.

Manual

GBxCart RW Manual Rev43

Download

Windows users should download the GUI or Console Interface/Console Flasher while Linux/Mac users can only use the Console Interface/Console Flasher. These updates work for the Mini v1.0 board and v1.2/v1.3 boards.

Mac users – We recommend trying an App called CartBoy which works with GBxCart RW, so far it supports GB/GBC for reading ROMs, backing up saves and restoring saves. It is faster than the console interface software.

    Just received the product from South Korea! Took approx. half a month to reach here(Used tracked AirMail) Works fine on Win10, easy installing driver! Tested out reading ROM and importing/exporting save files with no problem. I can’t thank more for this amazing product, I can save all my GBA cartridges safely now. Easy to use, Affordable price, What’s more to say? Excellent product mates. Highly recommended.

    Works great!
    The transport to Switzerland took about 2 weeks and about 2 week to make my order ready. For the long way from Australia is that alright.
    Good service, pleasant email support.

  3. Justin (verified owner)

    I received mine about 3 weeks after ordering, and it works as promised. I had to fumble a bit with driver installs and finding a ‘good’ USB cable before the computer would recognize it. Thanks!

  4. Michael T (verified owner)

    Took a while for me to get it to work but that was my own “screw the documentation” attitude. After actually reading and seeing how to check what kind of bootleg cart I got I was able to put the game I made with GBStudio on an actual Gameboy cartridge.
    Which is an amazing feeling too, child me would be freakin’ amazed haha.
    Cheers heaps and keep up the great work.

    I received the GBxCart RW (v1.3) in 3 weeks to spain. Arrived perfectly, and works perfectly. It´s fantastic I use it with windows 7 and Works perfectly I can extract GBA and GBC Saves and I ca flash ROMs in a Chinese flashcard. Great product I am glad with this buy!!!! Maybe in the future i use it to flash MultiROM FlashCard

  7. Shawn S (verified owner)

    Arrived to my US Doorstep around 2 weeks after I purchased it. Took around 1-2 days to ship. Works perfectly fine for extracting GBA and GBC Pokemom Saves. Might decide to use this in the future to flash ROM Hacks to it. Great product and would be happy to buy again!

  8. Bruno (verified owner)

    Very impressed with this device. Does all it claims and it does it well. I have the USB-C version, it works very well with Windows 10.

    Recieved it in 2 and a half week, and I live in France. Arrived perfectly perfectly, and works perfectly.
    I’m a Windows 7 user, and I would like to say that the GBxCart RW didn’t got recognized at first with the first USB wire I’ve used. Device Manager would not see anything either. I’ve then tried another USB wire, same thing. My 3rd wire I’ve used, the light on the board turned on, but same as above, the computer would not recognize anything.
    Of course, I did followed the quick steps and installed what was needed (including the “.inf” drivers), but nothing. I’ve even updated my computer’s drivers, just in case. With this 3rd wire, I’ve tried repeating the steps on all the PCs on the house (including one Windows 10), but same as before, still that light, but not recognized AT ALL. I was starting to think there was something wrong, until I’ve tried ANOTHER USB cable that I have, and tadaaa, it finally WORKED !

    So if you struggle to make it work, just know that the key for that is the USB cord that you use, not all with work, and usually, the not so long ones have a higher chance of working with the GBxCart RW !

    I can now transfer my pokemon from the 3DS Virtual Console to my Gameboy Cartridge, and then view them in 3D in Pokemon Stadium. It is amazing !

    Pour les non anglophones, ce que je peux vous dire, c’est que je l’ai reçu en 2 semaines et demi après expédition. Il est arrivé dans une petite envellope protégé à bulles, et il fonctionne du tonnerre. Je peux copier mes sauvegardes de mes cartouches Gameboy, Gameboy Color et GBA sur mon PC, et peux même transférer ces mêmes sauvegardes sur la cartouche elle même, ce qui vous permet de ne plus perdre la save quand la batterie est HS.

    J’ai par contre eu du mal à le faire fonctionner au début, car il n’était simplement pas reconnu par l’ordinateur sous Windows 7, ni même sous Windows 10. Malgrès une mise à jour de mes pilotes, rien n’y a fait. Il n’apparaissais nul part après branchement en USB. Il se trouve que le cable USB que j’utilisais ne fonctionnais pas du tout sur le GBxCart RW. J’ai testé de multiples cables, sans succes. Un de ces cables à fait réagir l’apareil en allumant les diodes, mais rien de plus, toujours pas reconnu. J’ai même pris la peine d’installer les drivers “.inf” fournis dans le dossier d’installation, mais toujours rien. J’ai essayé un nouveau cable USB (Un 4ème cable différent), je l’ai branché, et surprise, tout est reconnu parfaitement.
    Le truc important si rien ne marche, c’est le type de cable USB. Les cables court d’après ma propre expérience ont donné plus de resultats que les longs. Maintenant, l’apareil marche du tonnerre, et je n’ai plus aucuns soucis 🙂

    To make it short … it’s cheap and works like a charm. If you’re looking for something to backup your saves … this is the one you’ll need !

    Received mine a few weeks ago. It works great.
    Already flashed a few home made flashcarts and have had no issues dumping roms and sav files.
    Why pay more for other products that will do the same, or maybe even less, than this nifty little reader?

  11. davis.s (verified owner)

    Excellent product. Well documented.

  12. Andreas T (verified owner)

    Very straightforward manual, and user-friendly command line application for OS X (ran it on 10.14.4.) Quick delivery, also.

    Thank you very much for your help, appreciated.

    it’s an amazing device for bring to life your home brew games! , simple to use , arrived in 5 weeks to Colombia. thank you Alex.

  14. Andrew (verified owner)

    I love mine. Plenty of saves backed up and restored, and ROMs read and written.
    I’ve had one very weird issue with a flash chip that wasn’t normally supported. Using the GUI wouldn’t flash it, but using the console flash tool worked, but I got quick, thoughtful responses over on their Twitter!

  15. Marine (verified owner)

    A lovely little piece! It safely arrived in 13 days (Wisconsin, USA) and worked right out of the envelope. Its software is straightforward and simple, installation is super easy. It can be a little bit finicky with games that have sustained a bit of wear and tear, but it does its job very well.

  16. Rebecca (verified owner)

    Just received my GBxCart RW v1.3 from AU to UK with no issues.
    Really easy to use, simple user friendly interface to back up all your GB/GBA games + saves and RW carts.
    Absolutely love it – highly recommended.

  17. William (verified owner)

    I bought this to use with my Gameboy Camera. It’s really great — works well and shipped quickly. I think some Mac-specific instructions in the manual would be a great addition but the product itself is awesome.

  18. Simone

    Awesome.

    Ordered more than one year ago and still working. Useful for making backups and for playing your savestates on emulators.

  19. jamesy94 (verified owner)

    Excellent product. This is the cheapest GB/GBC/GBA cartridge reader I could find and it works perfectly for backing up ROMs and save games from cartridges and writing save games to cartridges.

  20. Luc

    Excellent product and support from insidegadgets.
    My computer was not recognizing the gbxcart-rw on Windows 10 or Linux so I reached out to insidegadgets. They responded within a day with some troubleshooting suggestions; turns out the micro-USB cable I was using was not working properly. I then copied my save games and Game Boy Camera photos seamlessly.

  21. Dave (verified owner)

    Would highly recommend this product. Worked brilliantly for extracting my old Pokemon GBA saves. It also shipped fast which was great.
    Cheers.

  22. Santiago

    Awesome product and support! It works perfectly. And just took 9 days from Australia to Madrid.

    Arrived faster than expected, took about a week to get to Michigan in the US. It was easy to setup and works exactly as expected.

  25. Owen (verified owner)

    This is a great easy to use card reader and works flawlessly on GBA and GB/GC , I bought this as I found a box full of old carts in a cupboard and have been successful in extracting the rom’s and saves from them and preserving the rom’s for my collection

  26. Hector

    great product, i bought my gbxcart from Chile and work really fine with my pokemon games, i extract the save data from virtual console version and inject in a gb cart AND WORKS, now i play pokemon stadium 2 with in my n64 console with my pokemons from virtual console save… its really cool

  27. JaeSeokK

    Very good product and seller. Perfect A/S.

  28. Brian G

    Best GBA save backup tool for the price. I got tired of buying flashcards to export my Pokemon Emerald save, glad I found this instead! I would recommend using a PS3 controller charging adapter to connect the GBX cart with your computer, because I tried a couple of other cheap USBs that did not work with the device.

  29. David D

    I bought this in February and it arrived about a week later here in the United States. The device requires a USB A-Male to Micro B Cable that was not included, however the one I bought off of Amazon worked just fine. I plugged the cable about halfway into the device because it still reads the data fine and it’s difficult to remove if I plug it all the way in. It dumped my game saves and ROMs perfectly! Its price and functionality easily competes with the other devices on the market. I would recommend this device if you are unwilling to spend $50-$70 on the various other devices for about the same functionality.

  30. F-Cee

    Just got my GBxCart RW here in France – really good product. Works as expected.Thanks for that product!

  31. Mitch S.

    Tested and reads/writes perfectly with GB/GBC/GBA games. Not gonna find a better device on market at this price point.

  32. Graham M

    GBxCart RW arrived safe and well in less than 8 business days to the UK. Very reasonably-priced product and postage & packaging is inexpensive.

    Amazingly the battery-backed saves for all my old Gameboy Carts from 1993-1994 were still intact and now I’ve got them backed up for good. It was nice to find these reminders of my youth!

    Thanks again Alex, for your wonderful product, great software and clear instructions.

  33. Vincenzo

    Bought GBxCart RW from Italy. Arrived in 3 weeks, everything perfect. Works like a charm!

  34. G.

    I have had the product delivered to Austria. Everything worked really well! Great product!

  35. Robert

    I received the GBxCart RW (v1.1) in 8 or 9 business days(Ohio, USA). I must say, I’m blown away by the ease of use and quality of the product. The board is is really nice and the software is very nice and easy to use. I was able to backup my save games easily and backup the ROMs. Very much recommend.
