R4 was out of stock in the past few weeks in Melbourne and I finally got it last week from acegamestore.com. They are selling 1GB and 2GB package in 80 and 100 aud. The whole packages comes with:
- R4 DS English Version
- 2.2GB MicroSD Card
- SD Reader
- Compact Disc Driver
- Protective Key chain
As you can see from the picture, the quality of R4 cartridge build was good. However, the quality of the USB SD Reader was poor, you can feel the light weight and made of cheap plastic. The driver CD comes with driver version 1.10, you should get the latest version 1.11 from R4 official site.
No additional software required, just copy and paste your desire file into the memory card and you are ready to go. Overall, this is a very impressive to go with if you own a DS.

Do you need to have your DS chiped to use a R4 card.
Thanks
