I have 3 flash cards. One is 2G F2A ULTRA and the other two are EZ Flash Popular Style. I also have a cable that is Flash2Advance High Speed Linker. It has 25 pin connector on one end and on the other side it has connector that connects to GBA SP. I don't know if I have everything or am I missing anything? How do I backup/copy roms to these cards. Thanks in advance for your time.
