That's the same cart I have, and I've flashed it to 2.02. (Well, I had to try. I was playing around with the support software and the FreeWing software under W2K, trying to do a memory grab with the result that the cart would boot to a black screen. Fortunately the update program revived it.)
However, I'm sure you could find someone closer to do the job, but I don't know if it's worth the trouble. I haven't found any differences yet, they haven't even corrected the spelling of their company name on the splash screen!
