I too have a 23G. I too have had it for some time. And I too would love to know when I can expect a working product. I would love to say that this card was inexpensive, and that I can chock this up to a learning experience, but sadly it wasn't.
What I did is D/L the latest RAR file, uncompressed it, and moved all the files to a PQI mSD card. I then used my *working* R4 Revolution to boot the mSD, selected the r6boot-2.0070-selfburn_for R6.nds file, and when prompted, swapped the R4 for the R6 Gold and hit 'A'. After I saw Successful, I rebooted off the PQI card.
What I get is a blue screen on the bottom that says:
Language ID: 5
<3 Korean chars...not sure what they say>
I have the _boot.nds file on the card. Can we be told when we can expect a fix, or at least be given the option of an exchange for a new card that works, or even *gasp* a refund?
