R4 SDHC

Hi, could you please tell me where I could get the latest firmware for the R4 SDHC card? Ive looked but when Ive downloaded it, it hasnt worked on my R4.
Also, if poss could you please let me know if Sonic Classic Collection and Sonic Sega Allstars Racing works on the R4 SDHC and if so, how could I get it working.Many thanks and much appreciated! :)

The best place to go to is your flashcarts website. It is usually on the flashcart or on the box/paper that came with it.Otherwise, go to www.linfoxdomain.com/ds and find your card, and download the latest firmware for it.

Return that card immediately and get a Acekard2i or CyclosDS because R4 SDHC are terrible. I know because I own one.
