How to format sd card for Pandora box

[pm4698]

Hello there. Santa came earlier this year and he brought me a Pandora's box 9D. I unscrewed the box and saw a piece of hardware with a 16GB SD card in it which is almost full. I saw that there are a few 3d games but i would like to add games from more consoles like N64, PS1, PS2, PSP etc.

I bought a Samsung 256GB sd card hoping to replace the existing one, downloaded roms. What i did first was to copy/page contents of existing SD card to the new one but system was not responding at all. I saw format of default SD card was FAT-32 and my new SD card was exFAT with no option to format it as FAT-32 ( i supposed that format was the reason that was not recognized).

I also tried to use Raspberry PI Imager and try to create an image of RetroPie in my new SD Card but again it wasn't recognized.

Any ideas of how to format/set up my new SD Card to be able to use it with Pandora's box 9D hardware?

Thank you all in advance

If the original SD was fat32 you need to format the card fat32.

Using pi images will not work its not a pi...

Pandoras boxes are their own unique little hardwares they are not easy to mod.

The 9D is not supposed to be upgradeable like the 6 for instance.
