I need help fixing an error I keep getting on my 'Game Boy Pro Max' Flash cart

Hello! I just got a package in the mail today from Retro game repair shop. It was my Game Boy flash cart. I've been trying to get it up and running for the past hour, but nothing is working. There are little to no tutorials online, and I have no clue what to do. I keep getting the error code "0XD2".

I believe that it's worth mentioning that this flash cart didn't come loaded with an SD card, and I'm using my own.


Here's where I bought the flash cart. https://retrogamerepairshop.com/pro...6&_sid=33d1df5ac&_ss=r&variant=43681957937324

Have you put the firmware on the SD card?

Idk beyond that, but you can ask in the GBA forum, these clone carts get discussed there too.

So sorry! I just saw this. My issue is resolved, but now I have a new problem. Whenever I try to load a ROM, I'm met with distorted 'Nintendo' text. It's only whenever I start to run a ROM, and I'm not sure how to fix this.
