How do I Save and Load My Pokemon Yellow, Crystal and Chaos Black Roms?

Question

How can I Save and Load my Pokemon Yellow, Crystal and Chaos Black Roms. Cause I can Save Yellow and Crystal But Chaos Black says Save Error, Change Extended memory pack or something... But when I save Yellow and Crystal and Yellow and Close My Visual Boy Advance it doesn't say continue it just says New Game and Options. Anyone got any ideas?

Ok.  Save in states by saving shift+f1,f2,f3 (etc.) and then loading it by pressing the respective f1,f2 or whatevver.

To save ingame, try options/emulator/flash 64k should make it save properly.
