  1. This is amazing. If you could make this work with iOS or Android then you would be on to a real winner. Id love to play Tetris online at the beach!

  2. If any company make this kind of console ill buy it no doubt

  3. When you say works with 'Android': do you mean that it will work on any android phone using a USB OTG adapter. This would be awesome to just plug into my phone than have to sit next to my computer

  4. Im really surprised why this hasn't blown up over the internet. Ive bought 2. look forward to testing it out

  5. This is incredible. Does the link cable adapter work with GBA games, or only GB games using a GBA link cable? Provided someone wrote the proper code for it, it would be cool to see it work with the GBA Pokemon games.

    Also, another interesting possibility is writing an AI to play GB Tetris against you. There are so many possibilities when a custom server is involved.

  6. This amount of work and love to engeneering, is just amazing. Keep it on!

  7. How did you do the reverse engineering? i want to see if its possible with pokemon games but idk how to even start dissecting it.

  8. It also be nice if you make it so everyone can join even if they don't have a game boy 🙂

  9. People are doing THIS and standard emulators STILL can't get standard link cable functionality down.

    At least on a pi, you could bind the link cable pins to GPIO for a standalone or even DIY adapter

  10. Imagine being the dev of the original game boy tetris game and seeing people play it online lol

  11. where you got the USB for this ? i wanna play tetris on multiplayer on my gb

  12. I wonder how hard it would be to get it working on emulators… DS/DSi/3DS too.

  13. Wow this is amazing, I literally just searched gameboy link and never in my 1993 kid mind could've imagined something like this!!

  14. I have an exam tomorrow and I am watching Tetris online

  15. Wow that is insane. It's crazy what people dream up.

  16. Bist du Albaner? 🤔

    Was soll das eigentlich mit dem Englischen ? 🤔

  17. @4:35 you mention that this adapter can even work on android phones. Now I want to ask does that mean it will work with a game boy emulator on android?

  18. Can this be upgraded with PC/Android emulators support too?

  19. but wait….this will mean…you could actually make a gamecube lan adapter, and make the same game server things to play melee online? or mario kart double dash with 2 different persons from different countries on one kart, something that never was possible and still not today in the newer versions?


  20. Is the junk sent to all other players in the game or to just one of them? In Tetris 99, you can choose who to target with junk and if there was a way to implement that, it would make large scale games much more playable

  21. Man, I wonder if it's possible to play faceball with this, could you imagine 16 player FFA on the gameboy

  22. Tool-Time - Basteln mit Holz und Strom says:

    Didn't found any answer about this: Is it also possible to connect gameboy emulator to real gameboy … and also didn't found solutions for connectiong 2 emulators over network. Best wishes

  23. If you ever THINK about doing the same thing but on Pokemon games, remember to put safety protocols! The game has some vulnerabilities that allow the attacker to brick the victim's save

  24. Red einfach Deutsch alter, dieser akzent ist sooooooo schlimm.

  25. As the biggest GB Tetris fan in the known universe, I love this

  26. Woran erkennt man einen deutschen der englische Videos macht?
    Unten rechts steht einfach Werbung

  27. This only has 150k views it should have over 150mil as it's a million dollar idea!

  28. make it so people without a usb to gb link adapter can play through pc
