This requires setting the extended and command mode bits in the header, and writing our own flashing code.

The Viper design uses a stupid 4 wire install, which means it doesn't have DO and CS lines hooked up, so it is crucial that nothing touches EXI channel 0 until we're done with it. This means no SRAM, no SP1 and no card slot A.

This is most likely not happening until I get my hands on a Viper.

I have a ViperGC with the parallel flasher, would you be interested in borrowing it to work on this? I just ordered a picoboot to test it out and am willing to lend it to you.

Seems like I forgot to update the op. A Viper was already donated to me for development purposes, I just haven't had much time to work on it yet.
Thanks for the offer though!
