Game Boy GB Pro Plus 1000 In 1 Game Cartridge For Nintendo Gameboy - Transparent Clear, Includes Retrotech Printed Instructions

Works perfectly in the ModRetro Chromatic. Come preloaded but I was only interested in the cartridge itself. Zero problems it just works.

The flashable catridge comes loaded with more games than you can imagine, on a 4GB branded microSD. I got this to use in my Modretro Chromatic, but I have tested it in my original Gameboy Color as well. The Cartridge is a solid build, high-quality parts, including the microSD, which on my was Sandisk brand. The cartridge seats well and boots instantly. The menu interface is somewhat cumbersome, however this comes with a short manual. Once you get used to the nuances it isn't too bad. I like having so many games on a single cartridge, especially when traveling for work. On my Modretro Chromatic, the button on the cartridge only resets the game. I have to toggle the unit off and then on again to switch games. Only a slight inconvenience since I typically play the same game for a long period of time. This is definitely worth the price if you are looking for a way to expand your game library on your GB or GBC.

Worked for two days and then stopped working. Giving me the 0xC4 error. Checked the sd card which is a SanDisk 4gb card in my pc. Card read just fine. Seems to be the socket the sd card sits in is cheap and contacts quit working. Terrible for only a couple of days use. Save your money and buy something a little better. This is just another one of those cheap Chinese, make a million of them as cheap as possible, and sell tons of them to make a quick buck. Would love to see a review of someone who has had it for awhile and I would be surprised if it was still working.

The best part about it is the ease of use and the functionality of the cart itself, it essentially writes the data via each usage so it's replicating the game cart it feels like. I love it definitely fulfilled my purposes and it works with the FPGBC flawlessly. Can't go wrong a must have. Especially for the video game preservationists out there.

folders are unorganized it has the same games in different folders and half of the games don't work besides that its good not worth the price just get one off aliexpress

Great value

Roms load but I can’t get unit to save games.

It works on a ModRetro Chromatic (unlike the EZ Flash Jr.) which is really nice. The only problem is that the button on the cartridge that is supposed to take you back to the games menu just resets the current game instead. There’s no way to get back to the games menu without turning your Game Boy off and then back on again. Other than that, it works great.

Waited a few weeks for it and froze/stopped working after playing a couple of games.
