You are misinformed. For starters ASIC's are not reprogrammable, and secondly, none of these cards have ASIC's implemented. They use FPGA's.
I find it hard to believe that a clone card also wouldnt hook up the necessary JTAG signals to also do reprogramming. If GW has the necessary hooks, it's 99.9% likely that a clone does as well. They might have a different programing method though, and the best bet for people in this situation is to just wait for their maker to make an announcement. Since we know GW puts bricking code in the past stuff, I wouldnt want to be blindly trying to program that with my own hardware.
This topic was actually discussed thoroughly shortly after the first clone carts came out and Gateway first announced that the Gateway 2.0 Update would require people to update their FPGA.
A couple of community members traced where the FPGA's JTAG pins lead to on the corresponding PCBs for both the Gateway and the Clone Carts and even posted pictures to show exactly how one could trace where these pins terminated.
On the Gateway, they lead to contacts placed facing towards the front of the cart. These were clearly meant to connect to the contacts on the cart slot of the 3DS when the Gateway Red Cart was inserted into the console.
In contrast, clone carts had these JTAG pins lead to contacts facing the back of the cart. These would not come into contact with anything when the clone cart is inserted into a 3DS. The contacts could, however, could possibly have been designed to be accessible through a separate, unknown specialized device.
Since access to the JTAG pins is necessary to reprogram the FPGA, it was the general consensus that it would be impossible to apply an FPGA update on the clone carts through a regular 3DS. There was some heated debate on whether the Gateway FPGA could be updated through a 3DS or not, since the console did not seem to have been built for doing that kind of thing. While most people generally believed it was possible but would require some really creative method of updating the FPGA, a good number outright declared it was completely impossible to do this. There were various technical reasons sited which I will not go into here for the sake of brevity.
With the release of the Gateway 2.0 Omega Private Beta, it appears that they did in fact find a way to use the 3DS to update the FPGA.
The lack of any physical connection between the JTAG Pins on the FPGAs of the Clone Carts to the 3DS, seems to completely rule out any sort if FPGA update through the 3DS. It does not mean, however that there will be no way to update the FPGAs of these clone carts at all. Even back then there were a few who were predicting that the R4i Gold Deluxe Team would probably begin selling an update kit which you could use to update your clone carts either through usb interface, or perhaps through an adapter which would provide leads that hook put the JTAG pins to the cart slot contacts in the 3DS. Some even speculated that this may have been their plan all along in order to earn supplementary income. After all, why else would they bother terminating the JTAG pins at the back of the cart if not for this reason?
One should take note, however, that these discussions were held during a period in which both Gateway and the Clone Carts were actively releasing updates and news to the community.
The fact that R4i Gold Deluxe and the other clone carts never released an update to address the Bricking Issue which heavily affected their Flash Carts, and their long silence shortly after the Bricking Fiasco began, seems to indicate that any further updates for the clone carts is quite unlikely.
In this kind of environment I would be more than a little surprised if the Clone Carts came out with a copy of the Gateway 2.0 Omega Private Beta Update, even if did require the purchase of a new Adapter / Update Kit.
