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

09:37 PM Feature #73: Implement ATX disk image support

So this is what I ended up with as a patch to atx.c.
I'm updating gTrackInfo on every disk change or access to dif... foft

04:40 PM Feature #73: Implement ATX disk image support

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

09:47 PM Feature #73: Implement ATX disk image support

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

09:39 PM Feature #73: Implement ATX disk image support

Updated to the v9 code.

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

09:57 AM Bug #74: Mounted disks don't always load

I guess a disk revolution at 288rpm is 200ms, so it must be ok timing wise to do the ack first. foft

The time spent on iii is in pf_open, the fat file system open. I guess this must do some work.

Thanks. It loaded more on the 400/800 rom (but not that far) and stopped early on the XL/XE. I think I have the patch... foft

08:41 AM Feature #73: Implement ATX disk image support

Hmm, Bandits just worked with no change. Perhaps related to the other sector error issue. foft

I'll put it up as atxv4 shortly.
Tested the few you sent. They all seem to work, except Bandits still does not pla... foft
