Hi guys pleez tell me wat is MAGIC 4 and it is a clone of which chip

[PS2]

Thanks for replying
But r u sure its a clone of magic 3.1
Is it worth getting this chip for 40$ inclluding soldering
But when i asked a person that can this modchip be switched OFF to play online he said he didnot know
And in many sites i hav heard that they say its a clone of MAGIC 3.0
So please tell me wat r ur views about getting this chip
And r u sure its a clone of magic 3.1
Thank u
