CubeODE sd card help!

[Cre8destr0y]

I just received my cube ODE. It came with a setup 64 GB full-size SD card preloaded with Swiss and works. I would like to increase the storage size to a 256 GB but I am having problems and hope someone can offer some has encountered this and may be able to offer a solution.

I purchased a Nintendo switch branded microSD card 256 GB -
SanDisk 256GB microSDXC Card, Licensed for Nintendo-Switch - SDSQXAO-256G-GNCZN

I set the card up according to the instructions that came in the printed booklet with the CubeODE. My only variation to the instructions included was I used the Mac disk utility as I was unable to use Rufus. The card was formatted in Fat32. When I launch the GameCube, it hangs and says an error please see manual for the GameCube.

- I also tried setting up a 128 GB Nintendo switch branded San disk micro SD card with adapter -
SanDisk 128GB microSDXC Card, Licensed for Nintendo-Switch - SDSQXAO-128G-GNCZN - Same thing happened.

- I also purchased a 128 GB full size SanDisk Extreme, pro sd UHS-I card sdxc - same situation.

I am loading all these cards, using the extender adapter.

Do I have a bad card and I need to return it, or am I doing something wrong?

As a long time Mac user, I wouldn't recommend formatting your SD cards with the Mac utility, especially the last ones as they tend to be overwhelminigly full of options where you can f...up the whole formatting if you don't know what you're doing. Maybe you have a Intel machine where you can run Windows, or borrow from a friend?

CubeODE is not really modern, are you sure it can support so big SD cards?
