R4 Video Games Memory Card，3DS Game Flashcard Adapter Support for NDS MD GB GBC FC PCE

Once you install whatever firmware you desire, it works like a charm. Everything you put on it runs perfectly.

I read other reviews that suggested this non-descript card is an ACE clone. I did a web search for the latest firmware, followed the instructions to format my SD card (which you will need to have one or get one separately), and it works without issue. A very cost effective solution and a good way to revive an old DS/DSI/DSI XL you might have laying around.

No issues found. Just downloaded the files, inserted then in the flashcart and everything worked.

Can confirm, Ace3ds firmware (or wood, both work) lets you run what you want to.

This card has worked great for me after putting in the work to set it up. Cant speak much to longetivity yet but so far this card has had no issues. Just know this isnt usable out of the box and requires some setup (all of which is easily found online).

It would be nice if it came with either instructions or at least the website url to get the kernel software for it but once you find it it works great.

The blank r4 cards worked best for me as I was able to customize each card specifically for each kid. They have enjoyed playing each of the different games Ive added. You just need to know where to get the software program a d the games to download and reddit is a good source for information. Im planning on buying more for the my other kids and myself.

It would have saved a lot of headache if they simply specified that you have to install Ace3DS+ for it to work; once I got that figured out though, it worked exactly like I wanted it to.

Not one of my DS systems could read this. It does not work please avoid ordering this. There are way better options.

Downloaded the ACE Wood firmware V1.62 .rar file onto the sd card and it worked, It crashed a bit at first, but now it works fine. Able to play nes and snes, as well as gb games with the emulators
