GameBoy GameJack Duplicator - What? 

get another game jack and copy from game jack to game jack until the game corrupts

I actually own a Game Jack that I got back in the day when the Game Boy was still popular, so I can probably answer a few questions: - This copier was made by UFO and sold mostly in China, Hong Kong, and Taiwan. I don't know how rare the Japanese varient is, but I think the Chinese version is more common(?). I own several UFO products. - I can see your missing the software CD which is used for connecting your Game Jack via parallel port to your PC. You would need a streight-through parallel cable to use it. - The game cards go up to 64Mbits. I know, because I own several 64Mbit cards with built in rumble feature. - Not only can you copy larger games with a bigger card, but you can also use a ROM header/BIOS to load multiple games on a single card and access them via a menu system. You would need to connect the base unit to your PC in order to create a multi-game ROM image. - This isn't the only system that can duplicate game cartridges without a PC! I also own a Touch Boy copier from Hachi Shi Co, and it looks like a Game Genie, except the extra cartridge slot on the back is used for duplicating games directly with your Game Boy system. It has 32Mbits internally and can store a maximum of 4 games at a single time. So with this card, you don't even need a docking station.

ahh the Gamebomination Advance, the ideal testing console.

This would be useful when swapping out save batteries in older games, as a way of backup up your save file.

This is actually pretty fire. Imagining an alternate reality where blank GBA/GB cartridges were sold for "backups"

4:15 “look at that, it’s bloody robo cop innit?” 😭 🇬🇧

Im incredibly impressed with just the speed of it! it copies them like nothing

Interesting item, good find Elliot :-)

I had one of these and used it for homebrew development almost 20 years ago! I remember making a clone of Space Invaders called "Space Evaders". The port is actually a parallel port.

I believe it's megabits, not megabytes. 16 Megabytes would have been an absolutely massive amount of flash storage for the early-mid 90s. Even 4 megabytes was quite a lot of flash storage. I think the largest gameboy ROM sizes were around 8 megabits, which is one megabyte.

This is interesting, I actually own one of these that I got in a Japanese game lot years ago and never knew what it was for. I've tried to look up information and it was hard to find anything, so it's great to learn a bit more. I have the version with the 4MB card

These were advertised in the states in I believe it was EGM, but it was never released. Although another accessory that was advertised was released for a brief moment...Bleem!...which I still actually own my PC copy & the 4 they made for Dreamcast

I just repaired my first broken Gameboy that I bought from eBay! Thank you for all the help in your videos

7:01 when you’re waiting for the food in the microwave

As a kid, this thing would have been killer to copy games so I could easily do link cable play with buddies!

Gosh I love your channel Elliot! Such wonderful gaming stuff! I also love the banter you're developing! It's so good! You're becoming a younger Ashens it seems with the sarcasm and wit, and I mean that in the best possible way. All you need now is a brown sofa

"it's bloody Robocop, innit?" is the most British thing I have heard in years. Thank you for that. It made me happy all day.

The GB camera might "work" with a big enough cartridge. From the point of view of the GB, the cartridge is always just storage. Special cartridge will expose dynamic data at specific addresses. It is possible that the cartridge would show a static image of what the camera was seeing when copying the cartridge.

funny how i subbed to you channel long time ago, but only recenlty i binge on it. lol I love everything GB nostalgia related :P

That is a cool bit of kit mate, very cool video

Damn that would have been super useful when I was younger, my cousin would get all the good GB games before me.

This is the sort of stuff that makes me love this channel.

Thanks for the warning ur earlier video I've been waiting for it! Thanks keep up the great content I love it and I'm addicted to your videos and content!

Thanks for the content Elliot, keep up the good work!!

I admire you bro! Keep up the good work

Awesome. I like how they've even for vent holes in for the voltage regulator. The PC connections is mostly likely to the parallel port.

I have this package of stuff as well as the 16M cart with rumble. Super cool back when it came out - I actually held on to a PC with a parallel port for longer than I should have just because of this gadget.

I like the GameJack! :D I can't wait to have it someday! Also, Charlie sure killed it on their role!

2:17 Correction - Megabit (Mb) and not Megabyte (MB) as mentioned here.

I had something similar, and I loved it. I remember playing the Zelda games over a very long road trip with the family. One legitimate use that I used mine for was to keep more than one game on a cart with a little menu. I would dump all my games to my PC, and then I would load the games that I wanted to play onto it. It was handy for that since I only had to have one cartridge for my favorite games.

you can mod those flash carts, inside that 4 meg card on the board is a socketed flash chip pop it out and put a bigger chip in, even if yours is a soldered one putting a bigger chip on is well worth it. an older channel(retro game tech) actually built one, he bought a load of chips and put a window on the cart, so you could just change the chip to swap the game.

Good times, love your enthusiasm about all the oddities in the Gameboy world

This item is perfect for those who want to preserve their save states and not to worry about the internal battery of the cartridge! Great video!

Thanks Elliot. Great Video. Its a parallel port, you can get parallel to usb adapter if you can not find a computer with one built in. Those are kinda wonky sometimes though

It should say "Get JACKED!" on the box

I remember this thing. Even back when they were still selling it I wondered why anyone would buy it over the Bung GB Xchanger with Doctor GB Card flash cart... which is the system I bought. I still have it but I loaned the 64meg Doctor GB Card v2 to a friend and his dad smashed it with a hammer. D: Yeah, his parents were separated and he was leaving for the weekend to spend time with his father. I loaded it up with a bunch of games including Pokemon Crystal, which was still Japanese-only at the time. It blew his mind! He probably thought that weekend was his only chance to play Crystal so I'm guessing that his father couldn't tear him away from the Game Boy... so he smashed it. I recently found it in a pile of stuff and realized that it still works if you press down the flash ROM chip. I reflow this stuff all the time so expect a repair video soon. :) In the years since I got a Bung Multi Xchanger for the PSX and a Bung Doctor V64jr 512, which works with the Doctor GB Card as part of the "Multi Game Doctor³" (MGD³) series of backup hardware. It lets me use the PlayStation as a CD-ROM drive for the N64! I'm still not sure if I can load games from the GB Card to the V64jr through a PlayStation, but it has the connections to make that possible.

Really like your videos!

Nice, I don't use a gameboy much lately, but I definitely see the use for it. My 6-8 years self would had loved it.

LMAO "it's my save" *literal beginning* 😂😂 I love it

A modern version of the GameJack is the GB01 Game Boy Cartridge Reader. Though it lacks the 4MB flashcart, it supports GBA games as well as GB and GBC. Mine has been invaluable in backing up my Pokémon saves.

5:06 Tetris for Jeff

Man, I do miss the old RU-vid intro. Although I've got quite acustomed with this new one, the old one does spark me joy.

Your an amazing youtuber and my favorite Nintendo youtuber

That's actually a really powerful device. Imagine doing this on switch.

From what I remember, the Game Boy Camera ROM looks for a specific connection within the cartridge to detect the camera when it boots - if it can't find that, the ROM won't boot up. I saw somebody once manage to remove the camera from the GB Cam cart and bridge a connection to trick it into thinking the camera was still there, but that was the only way it would work!

6:19 The cartridges actually swapped places! :D

I really love your videos

Cool Video! You should call the gameboy you made "Gameboy Advance XL"

cool way of saying a rom dump lol i've dumped loads of my friend's games

I couldn't help but chuckle when you went to try and put tetris in on the bottom cause the gba sp screen on your doohickey triggered your muscle memory 😂

Translucent plastic is my favourite retro 90s look, I want this just for that, let alone the real use

I'd love to see another video where you would test other games, like fangames, counterfeit games, Pokemon Gold or Silver with their clock system (if it works, it would have been the best way to clone mons!), and of course your own Retro Future Fangame!

Always cool to see weird (unusual) stuff :D greetings from Poland

great video, I seriously wish I had one of these and a few carts growing up. My parents couldn't afford two of each game me and my brother got so it would've been nice to use this for a few of the games that we both used to play often. I would have no problem playing my zelda on that thing and giving my little bro the real cart to play with. No way I'm putting my pokemon on there tho lol.

Team Rocket's anime scheme to steal pokemons during trade must've gotten the idea from Gameboy Jack!

I love ur vids Elliot plz post regularly and review the Gamebox m3

"It's bloody robocop innit" love that 😂

"Go to your mates house, and make a copy of his BRAND NEW game" 🤣

You remind me of what I coulda been like with electrical engineering and stuff but then I dropped out and went to the oil rigs love you 1996

Wow, what a nifty thing! Wish I had one of these back in the day.

I could totally use one of these, specifically for backing up saves

Was waiting for this from ur 2nd channel

you should try to overwrite an official cart

Translucent doesn't even mean invisible… it means semi-transparent.

I can see that being developed for rental services, not sure what data the parallel port puts out but maybe it could have been used for data logging and tracking rentals into database

If anyone is interested in a modern version of this check out the "GBxCart RW". It lets you backup and write ROMs to GB thru GBA. :) (saves and GB Camera pics too!) You will have to source a writable cartridge tho. I just use crappy reproduction carts of pokemon lol.

An OG version of the GBXCart. Nice!

This is awesome! Also, that's a parallel port.

Imagine using this for Pokemon. This would have been great to have for any multiplayer games that you only had one of.

I remember wanting one of these so bad back in the day. Those parallel ports haunt me though, I can never get anything to work with them these days🤣

funny enough some guy called Elliot Coll just uploaded a video a few hours ago saying he brought one of these!

Woah! So cool! I wish I had one!!

I have to say, you have reignited the flame inside of me to collect gameboys, accessories or even other old retro items. I started wayyyyyy before I found the channel, and as someone who was born just before the GBAs release.. I missed out on a lot of old tech. I started collecting bits n bobs when I was given my uncles Gameboy Pocket (which strangely enough, we found the battery cover in a completely different house. I eventually stopped trying to collect games and consoles after finding out how much I was spending per product... Amazon really wasn't the smartest of options. When I first found your channel I got into the mood to retry collecting consoles, games etc. After advertising Sendico (about a million times ;P) I had to check it out for myself and its wonderful. I've just ordered 6 or 7 products about an hour ago and I'm already hyped for it. Thanks for you content and everything you have done! Keep it up! (Apologies for the really long comment :D)

Brilliant video. It's it me or is your on air sign bulb gone on the R?

This would be perfect if you could store multiple games on that cartridge. You could just copy loads of games from friends or lent from a library/Blockbuster.

This is an amazing find.

I have a such one, but with 64M "Rumble" flash cart. It was bought many years ago in China.

Hi Elliot! Awesome device! Maybe if you publish some high quality pictures of the cartridge board, we are able to reverse engineer the cartridge pcb and make our own...

If you want blank flash carts they’re near impossible to find but most of the “reproduction” aka pirated games are just flash carts preloaded with a modified rom. Modified to save save data to flash instead of a battery held RAM

I always wanted one of these!

4:15 Look at that, its bloody robocop, innit?

you cannot use gb camera on a flashcart because it makes a checksum for the camera first, but you probably can backup your sram from the gb camera if you have any other playable rom that uses SRAM on the Flashcart and then with the PC port you can transfer your gb camera photos.

Just so you know, I have a 68 in 1 and it doesn't run on an agb or ags, you can press some buttons and it'll start a game, but most of the graphics don't load. Try putting it onto a dmg/mgb/cgb.

Pretty cool actually, nice video too

u was king in the 90es with this xd

Thank you Kanye, very cool

Man i haven't seen one of these in ages lol. I remember when pretty much everyone back in the day had to use some variant of those carts for lsdj before the popular options we have now.

I would have loved that device back in the day! Very cool device!

EZ-Flash Jr is the better buy because I just got one and love it. great video as always.

That would be awesome to have back in the day!

2:00 That's a DB-25 Parallel Port, these used to be pretty common in the 90s for all sorts of peripherals.

look on amazon for a USB to Parallel cable, thats what that port is. A modern PC might see this as a flash cart. Or you would have to find software for it. Also the cable can be used with another accessory you showcased recently but I have a bad memory and forgot what it was

I have a similar product for gameboy advance. If you search for "wise box" and "wise card" for gameboy advance you might find one or two floating around.

These are awesome for collectors who don't want to take out their expensive cartridges

i dont know if you're into old computer games but it would be a great idea to grab a pentium 3 system or something off ebay that has all the old ports for connecting weird accessories like this as well as enjoying some old dos/windows games if you want. Could probably find something for $200 or less

4:07 You can't just pull that guy out of nowhere and not expect everyone who's watching to die from sudden shock.

GB GAMEJACK: *exists* NINTENDO: hey that's illegal

Loved seeing this. It would be a cool item to have. I wonder if the 16mb cart would hold an gbc rom.

Damn it, now I need one of these as well.
