FA 10:01 PM EclaireXL Bug #74: Mounted disks don't always load
It doesn't seem to be happening as much although I did run into some weirdness a couple of times that might be related so I'll keep an eye on it. Farb
FA 10:00 PM EclaireXL 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

FA 04:09 PM EclaireXL Feature #73: Implement ATX disk image support
Ok, done and checked into v09 branch. Farb

FA 11:08 PM EclaireXL 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
FA 11:07 PM EclaireXL 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

FA 06:00 PM EclaireXL Feature #73: Implement ATX disk image support
I just tried it with SDrive Max and Eclaire in XL/XE mode. It loaded and I got to the point that the plane was on the runway ready for take-off. Farb
FA 03:58 PM EclaireXL Feature #73: Implement ATX disk image support
I just tested Bandits with SDrive Max and Eclaire XL in 800 mode. It works fine. You need to wait until the full game attract mode starts (e.g. full gameplay is shown with attacking ships moving on the screen).. The game loads from disk ... Farb

Fantastic! :-D Farb

Here's further info about those two disks:

See specifically the "copy protection" row.

I believe phantom and duplicate sector are synonymous. Yes, multiple sectors with the same number on a track. Both Agent U.S.A. and Bruce Lee have them in the disks that I provided. Farb

I quickly confirmed that changing $F7 to $EF didn't break any of the images I ran the Scanalyzer test and it returns the expected status codes. So I will check that fix into the SDrive repository later today. Thanks for pointing it out! Farb
FA 07:19 AM EclaireXL Feature #73: Implement ATX disk image support
Hmm, good point. The status bits are active low which would make $F7=11110111 and $EF=11101111. Bit 4 represents record not found so this may very well be a bug in the current ATX code. I will need to test and confirm. Farb

As you have already surmised, the status byte returned from loadAtxSector contains the FDC status bits. Are you taking inversion into account correctly? See page 185 of the Altirra Hardware Reference manual: http://www.virtualdub.org/dow... Farb

FA 11:27 PM EclaireXL Feature #73: Implement ATX disk image support
Ok, I tested v3 and saw a few things:
1. Agent U.S.A. and Goonies successfully loaded. Woohoo!
2. Bandits successfully booted when started in 48K Atari 400/800 mode but it causes a reboot when its tries to load the first level in dem...

Glad it is making progress. I did wonder if bug 74 had something to do with what I was seeing. Are you using the status byte that comes back from loadAtxSector? Farb
FA 07:28 AM EclaireXL Feature #73: Implement ATX disk image support
I did some further testing and something definitely seems quite wrong. I can understand timing problems causing duplicate sector or timing-based protection checks to fail, but it seems like everything I try is having problems.
Here's ...

FA 10:16 PM EclaireXL Bug #74 (Closed): Mounted disks don't always load
I have been seeing some strange disk loading behavior for the past few builds. Intermittently, when I mount a disk and cold reset the computer, it behaves like no disk is present and goes to the memo pad/self test. I haven't been able to... Farb
FA 10:14 PM EclaireXL Feature #73: Implement ATX disk image support
I should add (in case it wasn't completely clear) that all those titles work with the current version of atx.c. Farb
FA 10:06 PM EclaireXL Feature #73: Implement ATX disk image support
I just tried atxv2 as well.
It sounds to me like the "slow" parts are too slow and the "speed-ups" are too fast. I know, very scientific :-P If I had to guess from the sounds, it seems like revs are constantly being blown which is why...

FA 05:11 PM EclaireXL Feature #73: Implement ATX disk image support
I am not aware of anything that exists like that today but think it is an excellent idea. I have reached out to some Atari folks that may be able to help in creating such an ATX :-) Farb

FA 09:30 PM EclaireXL Feature #73: Implement ATX disk image support
That is great news. I'm happy to test it out. How do I make an .rpd from the .jic and/or .sof? Farb

FA 09:58 PM EclaireXL Feature #73: Implement ATX disk image support
I'm not sure what DELAY_T2_MIN, DELAY_T5_MIN, etc. actually represent here so unfortunately I can't comment on that specifically. But I wanted to point out that one thing the SDrive Max's ATX code does not simulate (because a real serial... Farb
