Hacking How can I download ROMS on to this Flash Card?

[Radiobread]

So, I have this flash card. It already has some ROMS but I want to delete them and put pokemon games on.

I have installed the drivers on my Windows 7 computer, and the EZ Client (v3.25) is installed in the same folder. When I connect the cable up to my computer and turn my GBA on with Start+Select, EZ Client doesn't recognise the device. The battery works, I can tell as the clock on the bottom of the GBA screen works when I power it on. Any idea of how I can fix this and get the ROMS I want on the flash card?

EDIT: Changed to EZFA Client 1.03. I now get the Nintendo logo to appear on the GBA when I hit Start+Select on BIOS but the client still says "Waiting for GBA connection...". It came with drivers for 98, 2k and XP SP1. copied my 7 drivers and stuff but it didn't want to work.

See guide: http://gbatemp.net/threads/using-virtualbox-to-manage-legacy-gba-flashcarts.275407/

It is applicable to other gba flashcarts as well.

thanks for your help, I got it working eventually and Pokemon Emerald and LeafGreen are on there - both are compatible with saving and multiplayer. I actually got it as a Christmas present for my brother.
