F2A is simple. Jack real cart into slot, plug usb->gba cable into transfer port. Turn on GBA holding sel+start so it stays on the boot screen. Open up software, click on BACKUP CART. Then select the cart size with the radio button and hit OK. You'll get some crap going across your GBA screen with an image in the back (mine has Gundam (Wing) Deathscythe). It'll roll some numbers by up to the total it intends to for the copy size you request. When it's done, file is where you set it to be on your PC.

It's that simple, and I really can't explain it easier short of using images and I have none.
