Firmware for Sunplus chipsets

[petesimon]

a guy in the this facebook community page http://www.facebook.com/241278666305379 said he needs a firmware for his generic camera that has chipset Sunplus SPC 1521A (HL 091). I found an A9 cam online that has the same (uh similar) chipset http://www.gearbest.com/action-cameras/pp_181894.html

Is any firmware available for these generic or fake eken / sjcam cameras (with Sunplus chips)?
