Yes, for me is not a limit. I have a 2GB SD Card which i use with MSX Core.
I think the Core is very old and not updated, i would like to know if there is enough space to emulate a MegaFlashRomSCC cartridge, which can improve much the compatibility with roms, expecially Linear type ones.
For example I have difficult to load recent "Tina's Adventure Island" rom released as free for digital download:> link <
I think a big update should be much appreciated as MSX is a good machine to play with
