Firmware upgrades for the R4i SDHC remain a mystery at present, with the team giving away few details about whether the card would be compatible with a further Nintendo firmware upgrade at a later point. It is likely that the internal firmware of the R4i SDHC is not upgradable, with frequent software updates allowing for compatibility with the latest applications and games. The latest R4i SDHC software is incredibly stable, however, and the team have updated the software extremely frequently over the last year. It is also one of the cheapest Nintendo DSi compatible cards on the market, a main selling point for many.
The R4i SDHC card is a sturdy and reliable card, ideal for the first time user of a Nintendo DSi card. It is also backwards compatible with all older Nintendo handheld consoles (the DS, DS Lite and DSi as well as the DSi XL). If a consumer wants to buy R4i SDHC or similar cards, the multimedia functions they give a DS and DSi console would be of benefit to them.
