Farb, are you still running into this with the latest builds? foft

10:00 PM Feature #73: Implement ATX disk image support

Ok, I just checked in a couple more changes. Your patch file should get pretty small now :-D Farb

That's great, thanks. foft

04:09 PM Feature #73: Implement ATX disk image support

Ok, done and checked into v09 branch. Farb

01:44 PM Feature #73: Implement ATX disk image support

Could it be changed somehow like this? i.e. move the avr parts to another file and add byte swapping? foft

11:08 PM Feature #73: Implement ATX disk image support

Oh, and let me know if there are things I can do in the atx.h/c code to make it easier for you to consume :-) Farb

11:07 PM Feature #73: Implement ATX disk image support

I just updated to atxv5 and confirmed that 107 all passes and the few games I tested worked great. Fantastic work!! Farb

I put this up as atxv5.
So 107 all passes, but 107 track35 seems to have a lot of NOKs... foft

Added more structure to the command handling (common ack/nak etc) and looking much better. More to do though... foft
