Should I format the sd card as NTFS or FAT32?
There is no NTFS support anywhere currently. Although it would be easier to add.

My microsd card is 255GB, is there any way to format it to FAT32? Doesn't FAT32 have a limit of 32GBs?

2TB maybe?
My 128GB SD is formatted as fat32 as far as I know.

I noticed that emgba doesn't work with GBA Video roms like Shrek on the GameCube, but it does work in Windows. I don't understand why though.

32 MiB ROMs aren't playable due to memory limitations, but 64 MiB ROMs like the Shrek movie should work (don't ask why).

if you think of a different scenario... Satoru Iwata designed 50 million NGC sold.
if that number had been reached...
how would NGC memory be expanded?
wouldn't a GBplayer support that?

It's interesting how the Nintendo Wii had a memory hidden in its megabit emproom...
the unknown is that
there is a hook in the function between mGBA {} GBI {} Cartridge slot = memory expansion...

It's been discussed before but elsewhere, there are RAM expansions in the form of GBA carts, Nintendo itself made one to get along Opera for DS, but it won't be as fast as memory expansion straight on the exp connector, still, it would have to cope with access to the GBPlayer, or the players would have to choose and plug the one they need each time they want one or the other.

Just look at what was done in terms of expansions for the TriForce cabinets. The Ram may have been considered sufficient for this console generation.

To get back on track, videos are read sequentially, so you don't have to store big chunks of memory, only a "minimum" for a FIFO stack. On the other side, games may access almost any adress in a rom, at any time, so you're supposed to be able to do that way faster than a peek on an SD card sector takes. Nonetheless, there existed some workarounds to use bigger size roms than cart's RAM, as there seems in the supercard's rom utility, but I fear it's only for DS's games that are not genuinely read the same way as the GBA ROMs.
