I've managed to get a micro SD going with multiple partitions and games on each of the partitions. However, it doesn't look like the GW3DS supports anything more than a single partition in the partition tables (either that or I'm just doing something wrong).
I'm gonna contact the GW team and see if they can take a look into this
Heres a quick guide if anyone wants to take a look into it:
1. Download bootice from here
2. In the "Physical Disk" section find your SD in the "destination disk" section and click "parts manage".
3. In the new window, click "re-partitioning" and select USB-HDD mode (Multi-partitions).
4. Configure the settings to your liking and let it format.
5. The SD is now partitioned with multiple partitions.
6. Download USB Image Tool from here
7. Extract, etc.
8. In the top left, select "volume mode" and select the volume you want to image with a ROM
9. Click the "restore" button and change the search options to "all files" and find your rom.
10. Let it image
11. Done
