I was planning to update my Nintendo DSi system software, but I'm afraid because when I update it, I can't play my R4i SDHC anymore. 1.4.1 update is the current update at Nintendo DSi system software and my flash card is R4i SDHC with Blue Box. And I read in this blog: http://www.r4i-software.com/nintendo-dsi-1-4-1-firmware-blocks-some-flash-carts/ R4i SDHC is one of homebrew flash cards unblocked. Can I update it?
