cheap and nasty ebay flash cart identification

[GBAtemp]

hey so i got one of those cheap cheap flash carts from china, it's white and has like.. a bit of the chip on the outside (what's the word for anti water proofing lmfao)? and no matter what firmware i throw at it (with an empty sd card it says "no find scfw.sc file!" which i've narrowed down to dstwo or something? no matter what fw i put in tho, dsone or otherwise, it just shows me a white screen. are these the kind of things to be bitchy about sd formats?
