The Joey Jr V2++ is the latest iteration of the easy to use game cart dumper / flasher by Benn Venn Electronics. 

V2++ is the fastest Joey Jr to date. 65% faster GBA dumping than V2CC, 35% faster GBC dumping. Flashing up to 35% faster.

Joey Jr needs no software or drivers. It works much like an external hard drive. You can drag your roms and save off, or on. You can play your cart directly in an emulator from the cart and saves will be automatically updated on the cart when you're done. Super easy to apply gameshark codes, high speed grinding, patching etc. Ideal for battery swaps, GB Camera image extractions, Save and ROM backups.

Cart compatibility:

All official GBA carts supported: ROM dumping, Reading and writing of all save types, EEPROM, SRAM, FRAM, Flash128k/Flash64k. 

All official GB & GBC carts supported: ROM dumping, Reading and writing of all save types SRAM, FRAM - Including GBA e-reader

GB camera image dumping is supported! All your images conveniently presented as bitmap files to your PC, tablet, phone etc.

Official Nintendo Power Cart multi rom support just added!

Unofficial cart Flashing: Third party carts are regularly sourced to check and add support where necessary. If you have an unsupported cart, head over to the BennVenn discord for support. If you provide all the details to Benn Venn they will try to ensure it's added to the next firmware update. 

Windows compatible - Mac compatibility not guaranteed but has been tested as working with older Mac from 2008 - It is generally expected that it will work with newer OS, you can ask in the discord for the latest information.

Transfer speeds:

GBA cart dumping 710kbytes per second - ~23 seconds for a 128mbit GBA cart (Pokemon for example).

GB/C cart dumping - ~330kbytes per second - 3 seconds to dump Pokemon Red, can boot in an emulator faster than on a real Gameboy.

GBA Bootleg Flashing speed up to 355kbytes per second - under 50 seconds to flash Pokemon Ruby (16mbytes) to your bootleg. 12minutes to reflash a 2048Mb GBA multi-cart

GB/C Bootleg Flashing speed - 90kbytes per second - 1mbyte ROM (Pokemon red) in 12seconds.

Finally being able to save years old important photos from the GB camera

I tried odering Game Boy dumping devices for a while now, but they were either not available, too expensive or my last try ended in getting messed with by the seller and the delivery service.

With this device, it finally worked out, and the device itself so far perfectly did what it's advertised for. I could easily dump the pictures from the Game Boy camera. Aside from saving photos from a deceased friend, I want to keep using this thing and having those pictures not trapped within this device.

I didn't do much else with it, but seems like you need to get used to the management of the pictures, since the device doesn't erase the photos from the camera, you still need to do this manually, and the device seems to keep previously copied photos in memory and show them to you, even though they are not there on the camera anymore. It's a little odd behaviour, but you can treat it as a backup.

So far, nothing for me to complain about, hopefully this thing will stay in working condition for many years to come.


Plug and play super easy with PC but I doesn't work with android nativity from what I can tell unfortunately still a great product especially for the price

Probably the best Gameboy dumper

This flasher is probably amongst the best for dumping GB/GBC/GBA games on the market. Super easy to set up, no faffing around with dodgy software, simply drag n drop like you would with any other USB drive. Very fast too! Excellent service provided by Zedlabz as well.

Perfect for Pokemon

This is a must have for backing up your gen 1, 2 and 3 Pokémon games! All you need to do is drag and drop your save file onto your computer to back it up. This is the same for putting the save file back onto the cart. Great for when you need to protect your save file from a dying battery. It arrived in a couple of days in really nice packaging. The protective housing on this model feels really high quality too. I'd recommend this store to anyone!

A genius piece of tech!

I purchased this a couple months ago along with Bennvenn's 8MB 128KB FRAM programmable Flash Cart MBC3 with RTC battery and with only a bit of working out and updating, I have the ability to play any gameboy game (Including fan made games!) on my original Gameboy color! This has the only real-time clock that actually works in my experience, great for Pokémon.
Can back those game saves up on my pc too.
Postage and service was Excellent!
